A water supply port 8 is further installed so that it communicates with the evaporation water tank 2 through the water supply port 8 and the water stored in the water tank 6 flows into the evaporation water tank 2 and is absorbed by the evaporator 3 . do. And an air outlet 7 should be further installed at the upper portion of the case 1, the air outlet 7 communicating with the air outlet end of the fan 4, and the evaporator 3 is a direct air outlet 7 It is installed in the air flow passage 11 between the air outlet end of the fan 4 and the air flow passage 11 is located between the inner wall of the case 1 and the outer wall of the water tank 6 , that is, the two An annular airflow passage is formed between the inner and outer walls of the That is, an airflow is generated by the rotation of the fan 4, and before the airflow is discharged from the air outlet 7, it first passes through the evaporator 3, and the moisture in the evaporator 3 is evaporated into water molecules, and the air outlet 7 ), thereby reaching the purpose of moistening the air. In order to ensure the compact structure of the humidifier and not to affect the air inlet at the bottom of the case (1), the motor of the fan (4) is installed in the case (1) and installed above the fan (4) , the motor 13 is power-connected to the fan blade. As can be seen from the above description, in the structure of the humidifier in this embodiment, the evaporator 3 is installed in the evaporation water tank 2 and is installed between the fan 4 and the water tank 6 .

In order to further reduce the inner space of the case 1, the evaporation water tank 2 is installed in the form of an annular groove as described above, and on this foundation, a prominent part is installed in the middle of the evaporation water tank 2, and the prominent part A cavity is formed inside the evaporator, and by installing the motor 13 in the cavity, the space between the cylindrical evaporator 3 and the evaporating water tank 2 can be effectively used.

Preferably, the water tank 6, the evaporator 3, the evaporation water tank 2 and the fan 4 are sequentially installed in the case 1 along the longitudinal direction as shown in FIG. 2, and the water tank (6), the central axis of the evaporator 3, the evaporating water tank 2, and the fan 4 overlap each other to make the overall volume of the humidifier smaller, thereby having a large-capacity water tank with the smallest volume. structure can be made more compact.

In this embodiment, the fan 4 is installed in the lower part of the evaporator 3 , the air inlet 5 is expanded in the lower part of the case 1 , and the fan 4 is generated while the motor 13 is running. The noise is blocked and absorbed by the evaporator 3, which effectively reduces the noise when the humidifier is running. Therefore, it is possible to increase the amount of humidification within a unit time by increasing the rotation speed of the fan. Then, the air flow passage 11 is installed between the outer wall of the water tank 6 and the case 1, and the evaporator 3 is enclosed in the lower part of the water tank 6, so that the vertical air flow passage 11 is formed. By forming the airflow passage 11 to reduce the obstruction to airflow, further reduce the volume of the humidifier, make the structure of the humidifier more compact, and combine with the air inlet 5 below to improve the aesthetics of the entire humidifier. can be improved

2, in one preferred embodiment of the technical means for solving the problems of the present invention, in order to optimize the structure of the airflow passage 11 and provide sufficient space for the evaporator 3 , the water tank 6 is directly designed to have a T-shaped cross-section, and as shown in FIG. 2 , the outline of the upper edge of the water tank 6 is the evaporator 3 forming the lower part of the water tank 6 . It is made larger than the edge contour of the lower part of the water tank 6 so as to be installed to surround it. When installed to surround the lower part of the evaporator 3 is matched with the lower part of the water tank 6, the lower part of the evaporator 3 is submerged in the evaporating water tank (2). Based on the above structure, preferably, the cross section of the water tank 6 is designed in a circular structure, and the shape of the evaporator 3 is designed in a cylindrical shape to save space, and the evaporator 3 is ) to surround the lower part, so that the horizontal contour area of the upper part of the evaporator 3 is larger than the horizontal contour area of the lower part of the evaporator 3, the evaporator 3 is made by overlapping the fiber layer, and the evaporator 3 ) The overlap density of the lower part is larger than the overlap density of the upper part of the evaporator 3, and through the structure in which the upper part of the evaporator 3 is loose and the lower part is dense, the volume of the unfolded part of the upper part is larger than the volume of the relatively dense part of the lower part do. For this reason, water in the evaporation tank 2 permeates smoothly into the evaporator 3 from bottom to top, and during the process of water in the evaporation tank entering the evaporator 3 from bottom to top by capillary action, most impurities in the water By filtering by the dense portion of the lower portion of the evaporator 3, the purity of the water entering the upper portion of the evaporator 3 is improved, and impurities in the water are prevented from entering the air together with the evaporation of the air stream. And through the structure in which the upper part of the evaporator 3 is loose and the lower part is dense, the airflow passage 11 is fully installed in the upper part of the evaporator 3, so that the airflow necessarily passes through the evaporator 3, and the evaporator ( At the same time as the moisture in 3) is evaporated, the moist evaporator 3 adsorbs and cleans the air passing through the airflow passage 11, that is, it is possible to adsorb fine dust in the air through the evaporator 3 . In the same way as described above, by installing a primary filtration net at the air inlet 5 of the case 1 and filtering relatively large particles in the air through the primary filtration net, it can respond to the adsorption action of the evaporator 3 .

At the same time, by making the evaporator 3 a variable diameter structure with a large upper part and a small lower part, the position occupied when the lower part of the evaporator 3 is put in the evaporation water tank 2 is reduced, and the width of the evaporation water tank 2 is reduced. The airflow passages on both sides of the water tank 2 can be widened, and the space utilization rate inside the case 1 can be increased. And, using the evaporator with a variable diameter structure, the smaller one with a higher density at the bottom has a dense overlap, and the larger one with a lower density at the top is loose. It can be effectively absorbed when passing through the evaporator, realizing a silent state, and the diameter variable evaporator with dense bottom and loose top can enhance the vortex and mass transfer effect of the airflow, and the liquid water in the evaporator can more easily convert water molecules As a result of using the variable diameter evaporator, the evaporation amount of the humidifier was increased from 283 ml/h to 435 ml/h according to the applicant's test on the mechanical specimen in the laboratory. At the same time, as described above, the small overlapping layer at the bottom of the evaporator blocks more impurities in the water, so that the impurities are not evaporated together with the liquid water.

Corresponding to the position of the mouth (8), the water inlet (8) is provided with a sealable rubber stopper, and the valve (9) ensures that a sufficient amount is always maintained in the evaporation water tank (2), and the valve (9) is The floating valve principle can be used, and when a predetermined amount of water is already filled in the evaporation tank 2, the float floats. At this time, the rubber stopper blocks the water supply port 8, and when the water in the evaporation tank 2 is insufficient , the float goes down and the other end of the valve 9 pushes up the rubber stopper of the water inlet to open the water inlet 8, so that the water in the evaporation water tank 2 is always kept constant, and the humidification amount is kept constant, It is not affected by the water level in the water tank (6).

Preferably, in order to conveniently put water in, a lid 10 may be further installed on the top of the case 1 , and the water tank 6 is installed just below the lid 10 , and the lid 10 . Water can be poured into the water tank 6 by opening the door or through a hole drilled on the lid 10 , and in this embodiment, the air outlet 7 is installed outside the edge of the lid 10 .

In addition, in order to suppress bacteria in the water inside the humidifier, in the preferred structure of the above embodiment, an ultraviolet sterilization lamp is installed inside the evaporation water tank 2 . 7, in this embodiment, the inventor further installs a water heating device 12 in the lower portion of the heavy water repellent tank 2 in order to increase the humidification efficiency of the humidifier, and the water heating device 12 The heating part of the evaporator heats the water in the evaporation tank through a heat transfer method to increase the amount of water evaporated in the evaporator 3 in contact with the bottom of the evaporation tank 2 . According to the experimental data of the inventor, when the temperature of the evaporator 3 increases, the evaporation amount is significantly increased, and according to the normal test standard, when the indoor humidity is 30% ± 5% in a temperature environment of 23 ± 5 ° C, the evaporation amount It was 400 ml/h, and when the temperature in the evaporator 3 was 35°C, the evaporation amount was 600 ml/h, and when the water temperature was 38°C, the evaporation amount was 900 ml/h. Therefore, by controlling the power and heating time of the water heating device 12, the water temperature in the evaporator 2 is always maintained in the range of 30 to 39° C., and the amount of humidification can be increased.

And, through experiments, the inventor found that raising the temperature of water not only helps to increase the amount of humidification, but also that the amount of humidification can be increased even if the entry temperature of air is increased. Based on this technical purpose, the air inlet (5) is installed on the bottom of the case (1), an air heating device (14) is installed on the bottom of the case (1), and an air heating device (14) is installed between the air inlet (5) and the fan (4), That is, when the fan 4 rotates, after the external airflow enters the air inlet 5, it contacts the air heating device 14 first, raises the temperature, and then the airflow passage 11 and the evaporator 3 By contacting with , the amount of humidification can be increased. The water heating device 12 and the air heating device 14 can heat water and airflow by an electric resistance or electromagnetic coil heating method, which will not be described in detail here.

As shown in FIG. 4 , during practical use of the above preferred embodiment of the present invention, when the fan 3 starts to rotate, the outside air flows through the airflow passage 11 through the bottom air inlet 5 of the case 1 . ), it comes into contact with the evaporator 3 in the airflow passage 11 , and then is discharged through the air outlet 7 at the top of the case 1 , thereby forming an airflow inside the case 1 . During this process, the airflow enters from the bottom of the case 1 and is discharged upward, and flows from the bottom to the top according to the direction perpendicular to the horizontal plane. Then, the water supply port 8 is opened through the valve 9 in the evaporation tank 2 so that the water in the water tank 6 flows into the evaporation tank 2, and the water level in the evaporation tank 2 is defined. When reached, the valve 9 closes the water supply port 8 through the float valve principle, and at this time, the lower part of the evaporator 3 is submerged in the water in the evaporation water tank 2, and the moisture gradually seeps into the fiber layer by capillary action. For example, by the action of the air flow, the moisture in the evaporator 3 is evaporated and continuously discharged to the air outlet 7 . By the continuous rotation of the fan 3, the process proceeds continuously, thus increasing the humidity in the surrounding air. When water injection is operated, if water is poured directly on the lid 10 , the water flows into the water tank through the hole on the lid 10 , and water can be poured into the water tank 6 by opening the lid 10 . have.
