Detailed Description
The invention is further elucidated below in connection with the accompanying drawings.
Referring to fig. 1, an embodiment of the present invention is a fan-down type evaporation humidifier, which includes an outer case 1, and as shown in fig. 2, a water storage tank 2 is provided in the interior of the outer case 1, an evaporator 11 is installed in the water storage tank 2, and when water is stored in the interior of the water storage tank 2, a lower portion of the evaporator 11 is in contact with water. More importantly, a fan 3 is installed below the evaporator 11, and the air inlet end of the fan 3 is communicated with the air inlet 4 at the lower part of the outer casing 1. And a water tank 5 is also arranged on the side surface of the outer shell 1, the water tank 5 is attached to the outer shell 1 for design, and the water tank 5 is communicated with the water storage tank 2 through a water inlet pipeline. An air outlet 6 is arranged above the outer casing 1, and the air outlet 6 is communicated with the air outlet end of the fan 3, so that the evaporator 11 is arranged between the air outlet 6 and the air outlet end of the fan 3. When the fan 3 rotates, air enters from the air inlet 4 and is discharged from the air outlet 6 after passing through the evaporator 11, and in the process, positive pressure is formed in the outer shell by the fan 3, and moisture on the evaporator 11 is blown out from the air outlet 6, so that the indoor humidification function is achieved. At the same time, since the sound wave is also affected by the air flow, the noise generated by the operation of the motor 10 of the fan 3 enters the evaporator 11 together with the air flow, and the noise wave is absorbed and isolated by the evaporator.
Based on the above embodiment, it is preferable that the outer contour of the outer case 1 is designed in a cylindrical shape for securing the aesthetic appearance of the evaporator design, and the fan 3 is required to be in power connection with the motor 10, and it is preferable that the motor 10 is installed in the outer case 1 and placed above the fan 3 for saving space, as shown in fig. 2. The power module is further designed in the outer casing 1, and the motor 10 is led out of a power line through the power module so as to be convenient for accessing an external power supply.
In this embodiment, the fan 3 is installed at the lower portion of the evaporator 11, and the air inlet 4 is additionally provided at the lower portion of the outer housing 1, as mentioned above, the noise generated by the motor of the fan 3 during the operation process is blocked and absorbed by the evaporator 11, so as to effectively reduce the noise generated during the operation of the humidifier, thereby increasing the rotational speed of the fan 3 to promote the humidification amount per unit time, further reducing the volume of the humidifier by designing the water tank 5 at the side surface of the outer housing 1, and improving the overall aesthetic property of the humidifier in combination with the underlying air inlet.
In a more preferred embodiment of the present invention for solving the technical problem, as shown in fig. 2, the water tank 5 may be directly designed into a ring-shaped structure and then surrounds the outer casing 1, or the inner wall of the ring-shaped water tank 5 may be directly used as the outer casing 1, so that the overall volume of the humidifier may be further reduced on the basis of ensuring the volume of the water tank 5. On the other hand, in order to avoid overflow caused by excessive water in the water storage tank 2, a mechanical valve can be additionally arranged on a water inlet pipeline between the water storage tank 2 and the water tank 5, and the mechanical valve can use the principle of a floating valve, when the water storage tank 2 has rated water, the water inlet channel is closed, and when the water in the water storage tank 2 is insufficient, the water inlet channel is opened, so that the water in the water storage tank 2 is always kept constant, and the humidification amount is kept constant and is not influenced by the liquid level in the water tank 5.
Further, in order to facilitate water addition, an annular water guiding groove 12 may be added at the upper portion of the outer casing 1, the annular water guiding groove 12 is communicated with the water tank 5 through the water adding port 7, then the cambered surface cover 8 is installed at the upper portion of the outer casing 1, the edge of the cambered surface cover 8 extends to the position right above the annular water guiding groove 12, and the gap air outlet 6 between the edge of the cambered surface cover 8 and the outer casing 1 is used as the air outlet 6.
Similar to the above structure, a water filling port 7 can be directly added on the water tank 5, then a cambered surface cover body 8 is installed on the upper part of the outer shell body 1, the edge of the cambered surface cover body 8 extends to the position right above the water filling port 7, and the preferable structure of the water filling port 7 is an annular opening structure which is suitable for the structure of the annular water tank 5. In this embodiment, the gap between the edge of the arc cover 8 and the outer casing 1 may be used as the air outlet 6.
So, through above-mentioned two kinds of structural design, when water tank 6 needs to add water, directly pour water to cambered surface lid 8, through the cambered surface structure on the lid, the water of adding can directly flow into water tank 5 through the lid edge, and the air current is discharged by aforementioned gas outlet 6 after the evaporimeter 11 simultaneously. Therefore, in the structure described in this embodiment, both water addition and air discharge are achieved through the gap between the edge of the arc cover 8 and the outer casing 1, but it should be noted that this does not mean that the air flow channel and the water flow channel in the humidifier are the same, but only the air flow channel and the outlet of the water flow channel are the same.
On the other hand, based on the above-described structural design, the evaporator 11 may be configured in a cylindrical shape, and an annular air flow passage 9 is formed between the evaporator 11 and the outer housing 1, and the air flow passage 9 communicates with the air outlet 6, so that the air flow generated by the fan 3 enters the evaporator 11 through the air flow passage 9 and is discharged through the air outlet 6. Preferably, the evaporator 11 adopted in this embodiment may directly adopt a cylindrical fiber filter element in the current mainstream air purifier, the fiber filter element may enable water in the water storage tank 2 to permeate from the lower part to the upper part through capillary phenomenon, evaporation is performed under the effect of positive pressure airflow, and the fiber filter element also has better isolation and absorption effects on noise waves, so that in the use of the humidifier, the fiber filter element may be replaced periodically as a consumable.
In another embodiment of the present invention for solving the technical problem, the inventor further improves the humidifier with the above structure to further increase the humidification amount of the humidifier. The inventor found through experiments that when water or air is heated, the humidification amount per unit time can be significantly improved, so based on the aforesaid experimental results, the inventor installs a heater below the aforesaid outer casing 1, the heater is placed between the air inlet 4 and the air inlet end of the fan 3, the heater can also be connected to the aforesaid power module, so as to facilitate the on-off of the controller circuit. When the fan 3 rotates to generate negative pressure air which enters the humidifier from the air inlet 4, the air passes through the heater firstly, and is contacted with the evaporator 11 after being heated under the action of the heater. The heater can be realized by resistance heating, electromagnetic coil heating or the like, and can be selected according to different requirements.
In actual use, as shown in fig. 1 to 4, according to the preferred embodiment of the present invention, when the power is turned on, the fan 3 starts to rotate, and outside air enters the air flow passage 9 from the bottom of the outer case 1, enters the inside of the air flow passage 9 from the outside of the cartridge evaporator 11, and is then discharged from the air outlet 6 at the upper portion of the outer case 1, thereby forming an air flow inside the outer case 1. In the process, a mechanical valve on a water inlet pipeline is opened to enable water in the water tank 5 to flow into the water storage tank 2, when the liquid level of the water storage tank 2 reaches a rated line, the mechanical valve is closed, at the moment, the lower part of the filter element evaporator 11 is soaked in water in the water storage tank 2, water gradually permeates upwards through capillary phenomenon, and under the action of the air flow, the water on the filter element evaporator 11 is evaporated and is continuously discharged along with the air outlet 6. When water needs to be added, water is directly sprayed on the cambered surface cover body 8, and the water enters the water tank from the water adding port 7 at the upper part of the water tank 5 along with the cambered surface structure of the cambered surface cover body 8, so that water is convenient to add, and any part of the humidifier does not need to be detached.
