Description

Technical Field

[0001] The present invention relates to an air improvement appliance, and more specifically, mainly relates to a fan-mounted air purification and evaporation humidification integrated machine. Background Art

[0002] As people's requirements for air quality continue to increase, a variety of small appliances for improving air quality have appeared on the market, such as air purifiers, air humidifiers, etc., but these small appliances can basically only complete air filtration and humidification, with single functions, and are not economical for ordinary families. And among the humidifiers on the market, the evaporative humidifier with better humidification effect uses a fan to generate airflow. When the airflow passes through the evaporator, the water molecules attached to the evaporator evaporate and are discharged together with the airflow, so that the indoor air remains moist. Since the fan needs to be driven by a motor and is installed above the humidifier housing, the rotation of the fan creates negative pressure in the housing to generate airflow, but the operation of the motor will also generate noise, which puts higher requirements on the sealing of the humidifier housing. At the same time, the fan speed is limited due to noise considerations, which in turn limits the maximum humidification capacity of the humidifier. Humidifiers of this type of structure are mostly water tank-mounted, and the airflow enters from the side of the housing and is discharged from the top. Such a structure not only cannot control the overall volume of the humidifier product, but also affects the aesthetics of its design. Therefore, it is necessary to further study and improve evaporative humidifiers of this type of structure. Summary of the invention

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

DETAILED DESCRIPTION

[0023] The present invention will be further described below in conjunction with the accompanying drawings.

[0024] refer to Figure 1 As shown, one embodiment of the present invention is a fan-mounted air purification and evaporation humidification integrated machine, the humidifier comprises an outer shell 1, combined with Figure 2As shown, a water storage tank 2 is provided inside the outer shell 1, and the water storage tank 2 is preferably designed to be annular or disc-shaped, so that an evaporator 11 can be placed in the water storage tank 2. When water is stored in the water storage tank 2, the lower part of the evaporator 11 is in contact with the water. The function of the evaporator 11 is to adsorb the water in the water storage tank 2 onto the evaporator 11 through the capillary principle, and then evaporate under the action of the air flow; a fan 3 is also required to be installed below the evaporator 11, and the air inlet end of the fan 3 is connected to the air inlet 4 at the lower part of the outer shell 1; more importantly, an air filter element 12 is also required to be installed in the aforementioned outer shell 1, The function of the air filter 12 is to first filter the air entering from the air inlet 4 and then entering the evaporator 11. The air filter 12 is installed between the air inlet end of the fan 4 and the air inlet 4 of the outer shell 1, and the air inlet end of the fan 3 is connected to the inside of the air filter 12, and the air inlet 4 of the outer shell 1 is connected to the outside of the air filter 12; the remaining parts can be sealed to ensure that after the air enters from the air inlet, it enters the inside of the air filter 12 from the outside, thereby completing the filtration; the air filter 12 can directly use the HEPA filter commonly used in air purifiers on the market.

[0025] In addition, based on the above structure, a water tank 5 can be installed on the side of the outer shell 1. The water tank 5 is designed to be attached to the outer shell 1. The water tank 5 is connected to the water tank 2 through a water inlet pipe, so that the water stored in the water tank 5 can flow into the water tank 2 and be absorbed by the evaporator 11. An air outlet 6 is provided on the top of the outer shell 1. The air outlet 6 is connected to the air outlet end of the fan 3, so that the evaporator 11 is placed between the air outlet 6 and the air outlet end of the fan 3. Therefore, when the fan 3 rotates, the gas enters from the air inlet 4, first passes through the air filter 12, and then passes through the evaporator 11 and is discharged from the air outlet 6. In this process, the fan 3 rotates inside the outer shell to blow the moisture on the evaporator 11 out of the air outlet 6, thereby playing the role of indoor humidification and air filtering and purification; at the same time, since the sound wave is also affected by the air flow, the noise generated by the operation of the fan 3 motor 10 will enter the evaporator 11 along with the air flow, and the noise wave will be absorbed and isolated by the evaporator.

[0026] Based on the above embodiment, preferably, in order to ensure the aesthetic design of the evaporator, the outer contour of the outer shell 1 can be designed as a cylinder. At the same time, the fan 3 needs to be connected to the motor 10. In order to save space, it is best to install the motor 10 in the outer shell 1 and place it above the fan 3. Figure 2 As shown; a power module is also designed inside the outer shell 1, and the power line of the above-mentioned motor 10 is led out through the power module to facilitate access to an external power source.

[0027] In this embodiment, by integrating the air purification unit and the humidification unit into the same outer shell 1, and using the same fan 3 as the airflow power unit, air purification and humidification can be completed at one time, the utilization rate of the fan is improved, and the use and purchase of the machine are more economical; and by installing the fan 3 between the evaporator 11 and the air filter 12, and adding an air inlet 4 at the lower part of the outer shell 1, as mentioned above, the noise generated by the fan 3 motor during operation can be blocked and absorbed by the evaporator 11 and the air filter 12, thereby effectively reducing the noise during the operation of the humidifier, so the humidification amount per unit time can be increased by increasing the rotation speed of the fan 3, and by designing the water tank 5 on the side of the outer shell 1, the size of the machine can be further reduced, and the overall aesthetics of the all-in-one machine can also be improved in combination with the lower air inlet.

[0028] Based on the above embodiments, it is preferred that Figure 2 As shown, the air filter 12 is placed directly below the fan 3, and the fan 3 is placed between the evaporator 11 and the air filter 12 to reduce the wind resistance in the outer shell 1, thereby reducing noise and keeping the internal structure of the all-in-one compact. In order to facilitate the replacement of the air filter 15, a hole can be opened on the side of the outer shell 1 and a filter removal door 16 can be installed. Based on the above ideas, the air outlet 6, fan 3, evaporator 11 and air filter 12 can be installed in the outer shell 1 in an overlapping manner on the same straight line perpendicular to the horizontal plane to ensure that the air flow channel can connect the four at the shortest distance, which can not only improve the efficiency of humidification and air filtration, but also further reduce the noise of the all-in-one operation.

[0029] Refer to Figure 2 As shown, in a more preferred embodiment of the present invention for solving the technical problem, the water tank 5 can be directly designed as an annular structure and then surrounded by the outer shell 1, or it can be understood that the inner wall of the annular water tank 5 is directly used as the outer shell 1. Such a design method can further reduce the overall volume of the humidifier 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 tank 2, a mechanical valve 13 can be added to the water inlet pipe between the water tank 2 and the water tank 5. The mechanical valve 13 can utilize the principle of a float valve. When the water tank 2 already has the rated water volume, the water inlet channel is closed. When the water volume in the water tank 2 is insufficient, the water inlet channel is opened, so that the water volume in the water tank 2 is always kept constant, thereby keeping the humidification amount constant and not being affected by the liquid level in the water tank 5.

[0030] Combination Figure 3As shown, further, in order to facilitate the addition of water, an annular water guide groove 12 can be added to the upper part of the above-mentioned outer shell 1, and the annular water guide groove 12 can be connected with the water tank 5 through the water filling port 7, and then the curved cover body 8 is installed on the upper part of the outer shell 1, and the edge of the aforementioned curved cover body 8 is extended to directly above the annular water guide groove 12, and the gap air outlet 6 between the edge of the curved cover body 8 and the outer shell 1 is used as the aforementioned air outlet 6.

[0031] Similar to the above structure, a water inlet 7 can be directly provided on the water tank 5, and then a curved cover 8 can be installed on the upper part of the outer shell 1. The edge of the curved cover 8 extends to directly above the aforementioned water inlet 7. The preferred structure of the aforementioned water inlet 7 is an annular opening structure adapted to the structure of the annular water tank 5. In the present embodiment, the gap between the edge of the aforementioned curved cover 8 and the outer shell 1 can be used as the aforementioned air outlet 6.

[0032] Thus, through the above two structural designs, when the water tank 6 needs to be filled with water, water is directly poured into the arc-surface cover 8. Through the arc-surface structure on the cover, the added water can directly flow into the water tank 5 through the edge of the cover, and the airflow passes through the evaporator 11 and is discharged from the aforementioned air outlet 6. 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-surface cover 8 and the outer shell 1, but it is worth noting that this does not mean that the airflow channel and the water flow channel in the humidifier are the same channel, and it should only be understood that the outlets of the aforementioned airflow channel and the water flow channel are the same.

[0033] On the other hand, based on the above-mentioned structural design, the evaporator 11 can be designed to be cylindrical, and an annular airflow channel 9 is formed between the evaporator 11 and the outer shell 1, and the airflow channel 9 is connected to the air outlet 6, so that the airflow generated by the fan 3 enters the evaporator 11 through the airflow channel 9 and is then discharged from the air outlet 6; preferably, the evaporator 11 used in this embodiment can directly adopt the cylindrical fiber filter element in the current mainstream air purifier, and the fiber filter element can make the water in the water storage tank 2 penetrate from the bottom to the top through capillary phenomenon, and evaporate under the action of positive pressure airflow, and the fiber filter element also has better isolation and absorption effect on noise waves, so during the use of the humidifier, the fiber filter element can be replaced regularly as a consumable.

[0034] In another more preferred embodiment of the present invention for solving the technical problem, in order to inhibit bacteria in the water in the humidifier, as the preferred structure of the above embodiment, an ultraviolet sterilization lamp can be installed inside the water storage tank 2. At the same time, in order to further improve the humidification capacity of the humidifier, the inventor found through experiments that when the water in the water storage tank is heated, the humidification capacity per unit time can be significantly improved. According to the test standards in the national standards GBGB / T 23332-2018 and GB 21551.2-2010, in an environment with a temperature of 23±5℃, the indoor humidity is 30%±5%, and the evaporation capacity is 400ml / h. When the water temperature on the evaporator 3 reaches 35℃, the evaporation capacity is 600ml / h. When the water temperature reaches 38℃, the evaporation capacity is 900ml / h. Therefore, based on the above test results, reference Figure 4 As shown, the inventor installed a first heater 14 at the lower part of the water tank 2, and the heating part of the first heater 14 is in contact with the bottom of the water tank 2, so as to heat the water in the water tank by heat transfer, so as to increase the evaporation amount of water through the evaporator 11, and to increase the humidification amount by keeping the water in the water tank 2 in the temperature range of 30-38°C at all times.

[0035] Furthermore, the inventor has found through experiments that not only increasing the water temperature helps to increase the humidification amount, but also increasing the temperature of the intake air can also increase the humidification amount. Based on this technical purpose, the air inlet 4 can be designed at the bottom of the outer shell 1, and then a second heater 15 is installed inside the outer shell 1, and the second heater 15 is placed between the air inlet end of the fan 3 and the air filter 12, that is, when the fan 3 rotates, the external airflow enters from the air inlet 4, first filtered by the air filter 12, and then contacts the second heater 15, and then enters the above-mentioned airflow channel 9 and contacts the evaporator 3 after the temperature is increased, thereby increasing the humidification amount. The aforementioned first heater 14 and second heater 15 can heat the water and airflow by heating with a resistor or an electromagnetic coil, and can also be selected according to different needs, which will not be described in detail here.

[0036] refer to Figures 1 to 4As shown, in actual use of the above preferred embodiment of the present invention, when the power is turned on, the fan 3 starts to rotate, and the external air enters from the bottom of the outer shell 1, first enters the interior of the air filter 12 through the outside, and completes air filtration and purification; then flows upward from the inside of the air filter 12, heats up after contacting with the second heater 15, and then enters the air flow channel 9 from the outside of the evaporator 11 to the inside, and then is discharged from the air outlet 6 at the upper part of the outer shell 1, thereby forming an airflow inside the outer shell 1; in this process, the mechanical valve 13 on the water inlet pipe is opened to allow the 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 the rated line, the mechanical valve 13 is closed. At this time, the lower part of the filter element evaporator 11 is immersed in the water in the water storage tank 2, and the water gradually penetrates upward through capillary phenomenon. Under the action of the aforementioned airflow, the water on the filter element evaporator 11 is evaporated and continuously discharged through the air outlet 6.

[0037] When water needs to be added, water is directly poured on the arc cover 8. The water will flow into the interior of the water tank through the water inlet 7 at the top of the water tank 5 along the arc structure of the arc cover 8, thereby making it convenient to add water without disassembling any parts of the humidifier.

[0038] When there is no water in the water tank 5 and the water storage tank 2, the fan 3 can also be started, and the all-in-one machine can be used simply as an air purifier, and its function is the same as that of the filter-type air purifier on the market.
