Description

Technical Field

[0001] The present invention relates to an air improvement appliance, and more specifically, mainly relates to a silent 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

DETAILED DESCRIPTION

[0024] The present invention will be further described below in conjunction with the accompanying drawings.

[0025] refer to Figure 1 and Figure 2As shown, one embodiment of the present invention is a silent air purification and evaporation humidification integrated machine, which includes an outer shell 1, a water storage tank 2 is provided inside the outer shell 1, and the water storage tank 2 is preferably designed to be ring-shaped or disc-shaped, so that an evaporator 3 is placed in the water storage tank 2. The function of the evaporator 3 is to adsorb the water in the water storage tank 2 onto the evaporator 3 through the capillary principle, and then evaporate under the action of the air flow; a fan 4 is installed below the aforementioned evaporator 3, and the fan 4 can be placed at the bottom layer of the outer shell 1, and the air inlet end of the fan 4 is connected to the air inlet 5 of the outer shell 1; importantly, a fan 4 is also installed in the outer shell 1 An air filter 15, the function of which is to first filter the air entering from the air inlet 5 and then contact the evaporator 3. The air filter 15 is installed between the air inlet end of the fan 4 and the air inlet 5 of the outer shell 1, and the air inlet end of the fan 4 is connected to the inside of the air filter 15, and the air inlet 5 of the outer shell 1 is connected to the outside of the air filter 15; 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 15 from the outside, thereby completing the filtration; the air filter can directly use the HEPA filter commonly used in air purifiers on the market.

[0026] In addition, based on the above structure, a water tank 6 is required to be installed on the upper part of the outer shell 1. The function of the water tank 6 is to store water. At the same time, in order to save space, the evaporator 3 can be installed around the lower part of the water tank 6. At the same time, the water tank 6 is also connected to the water storage tank 2 through a water inlet 8, so that the water stored in the water tank 6 can flow into the water storage tank 2 and be absorbed by the evaporator; in addition, an air outlet 7 is required to be provided on the upper part of the aforementioned outer shell 1, and the air outlet 7 is required to be connected to the air outlet end of the fan 4, and the aforementioned evaporator 3 can be directly placed between the air outlet 7 and the air outlet end of the fan 4; that is, when the fan 4 rotates to generate airflow, the airflow first passes through the evaporator 3 before being discharged from the air outlet 7, so that the moisture on the evaporator 3 is evaporated into water molecules and discharged from the air outlet 7 with the airflow, thereby achieving the purpose of air humidification. In order to ensure the compactness of the humidifier structure and not affect the air inlet at the bottom of the outer shell 1, the motor of the fan 4 is installed in the outer shell 1 and placed above the fan 4, and then the motor 13 is connected to the fan 4 by power.

[0027] In this embodiment, by integrating the air purification unit and the humidification unit in the same outer shell 1, and using the same fan 4 as the airflow power unit, air purification and humidification can be completed at one time, thereby improving the utilization rate of the fan and making the use and purchase of the machine more economical; and by installing the fan 4 between the evaporator 3 and the air filter 15, since sound waves are more likely to propagate in the direction of the airflow, the noise generated by the motor 13 of the fan 4 during operation can be blocked and absorbed by the evaporator 3 and the air filter 15 below, thereby effectively reducing the decibel number of the noise when the all-in-one machine is running. Therefore, the air humidification and filtration amount per unit time can be increased by increasing the rotation speed of the fan 4, and by surrounding the evaporator 3 at the bottom of the water tank 6, the size of the machine can be further reduced, and the overall aesthetics of the humidifier can also be improved in combination with the lower air inlet 5.

[0028] Based on the above embodiments, it is preferred that Figure 2 As shown, the air filter 15 is placed directly below the fan 4, and the fan 4 is placed between the evaporator 3 and the air filter 15 to reduce the wind resistance in the outer shell, thereby reducing noise, while 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.

[0029] Based on the above embodiment, it is more preferred that in order to further reduce the noise during the operation of the above-mentioned fan 4, one or more layers of sound-absorbing cotton 17 can be installed on the inner wall of the outer shell 1, and the position of the sound-absorbing cotton 17 corresponds to the position of the evaporator 3, so that the sound-absorbing cotton 17 can absorb the noise generated by the fan motor and reduce its decibel number.

[0030] Still reference Figure 2 As shown, in a more preferred embodiment of the present invention for solving the technical problem, the water tank 6 can be directly designed as a structure with a T-shaped longitudinal section, so that the evaporator 3 can be installed around the lower part of the water tank. As shown in the figure, when the cylindrical evaporator 3 is installed around the lower part of the water tank 6, the evaporator 3 fits with the lower part of the water tank 6, and the two form a columnar body with the same size from top to bottom; based on the aforementioned structure, it is preferred that the water tank 6 can be designed as a structure with a circular cross-section, and the shape of the aforementioned evaporator 3 can be designed as a cylindrical shape, and in order to ensure that the evaporator 3 has the performance of a capillary tube, a fiber filter element can be used as the aforementioned evaporator 3. When the humidifier is used, the evaporator 3 of the aforementioned fiber filter element and the air filter element 15 are both replaceable consumables, and in order to match the aforementioned structure, the outer contour of the aforementioned outer shell 1 can also be designed as a cylindrical shape.

[0031] On the other hand, combined Figure 3As shown, in order to avoid overflow caused by excessive water in the water tank 2, a mechanical valve 9 can be installed in the water tank 2. One end of the mechanical valve 9 corresponds to the position of the water inlet 8. A sealable rubber plug is installed on the water inlet 8. The mechanical valve 9 can always keep a sufficient amount of water in the water tank 2. The mechanical valve 9 can use the principle of a float valve. When the water tank 2 already has a rated amount of water, the float floats up, and the water inlet 8 is closed by the rubber plug. When the water in the water tank 2 is insufficient, the float drops, and the other end of the mechanical valve 9 lifts the rubber plug on the water inlet to open the water inlet 8, so that the water amount in the water tank 2 is always kept constant, thereby keeping the humidification amount constant and not being affected by the water level in the water tank 6.

[0032] Furthermore, to facilitate the addition of water, a cover body 10 can be installed on the top of the outer shell 1, and the water tank 6 is placed directly below the cover body 10. Water can be added to the water tank 6 by opening the cover body 10 or through the through holes on the cover body 10. In this embodiment, the aforementioned air outlet 7 can be designed on the outside of the edge of the cover body 10.

[0033] Based on the above structure, still refer to Figure 1 As shown, in another embodiment of the present invention, in order to minimize the wind resistance in the outer shell 1 and further reduce the noise of the humidifier operation, an air flow channel 11 can be specifically designed between the outer wall of the water tank 6 and the inner wall of the outer shell 1, and the above-mentioned evaporator 3 is placed in the air flow channel 11, and a gap is maintained between the evaporator 3 and the outer wall of the water tank 6 and the inner wall of the outer shell 1, and the air flow channel 11 needs to be connected to the air outlet 7 and the air outlet end of the fan 4 respectively, and the above-mentioned sound-absorbing cotton 17 is located in the air flow channel 11, and the sound-absorbing cotton 17 cooperates with the evaporator 3 in the air flow channel 11 to reduce the noise generated by the fan motor and the air flow itself; under the action of the air flow channel 11 structure, when the fan 4 rotates to generate air flow, a part of the air flow enters the interior of the evaporator 3 through the air flow channel 11, passes through the evaporator 3 and is then discharged from the air outlet 7, and the other part of the air flow passes through the outside of the evaporator 3 through the air flow channel 11 and is discharged from the air outlet 7. That is, in this embodiment, by having two air flows contacting the evaporator 3 at the same time, the humidification amount per unit time can be further increased; and preferably, the above-mentioned air outlet 6, fan 3, evaporator 11 and air filter element 12 can be installed in the outer shell 1 so as to be overlapped 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 integrated machine operation.

[0034] On the other hand, in order to inhibit bacteria in the water in the humidifier, as a preferred structure of the above embodiment, an ultraviolet sterilization lamp can be installed inside the water storage tank 2; Figure 4As shown, in this embodiment, in order to improve the humidification efficiency of the all-in-one machine, the inventor also installed a first heater 12 at the lower part of the water storage tank 2, and the heating part of the first heater 12 is in contact with the bottom of the water storage tank 2, so as to heat the water in the water storage tank by heat transfer, so as to increase the evaporation amount of water through the evaporator 3. The inventor found through experiments that when the water in the water storage tank is heated, the humidification amount per unit time can be significantly improved. According to the national standards GBGB / T 23332-2018 and GB According to the test standard in 21551.2-2010, in an environment with a temperature of 23±5℃, the indoor humidity is 30%±5%, and the evaporation amount is 400ml / h. When the water temperature on the evaporator 3 reaches 35℃, the evaporation amount is 600ml / h, and when the water temperature reaches 38℃, the evaporation amount is 900ml / h. Therefore, by controlling the power and heating time of the aforementioned first heater 12, the water in the water storage tank 2 can always be maintained in the temperature range of 30-38℃, thereby improving the humidification amount.

[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 incoming air can also increase the humidification amount. Based on this technical purpose, the air inlet 5 can be designed at the bottom of the outer shell 1, and then a second heater 14 is installed inside the outer shell 1, and the second heater 14 is placed between the air inlet end of the fan 4 and the air filter 15, that is, when the fan 4 rotates, the external airflow enters from the air inlet 5, is first filtered by the air filter 15, and then contacts the second heater 14, and then enters the above-mentioned airflow channel 11 and contacts the evaporator 3 after the temperature is increased, thereby increasing the humidification amount. The aforementioned first heater 12 and the second heater 14 can heat the water and the airflow by heating with a resistor or an electromagnetic coil, which will not be described in detail here.

[0036] refer to Figure 4As shown, in actual use of the above preferred embodiment of the present invention, when the power is turned on, the fan 4 starts to rotate, and the external air enters from the air inlet 5 at the bottom of the outer shell 1, first enters the inside of the air filter 15 through the outside, and completes air filtration and purification; then flows upward from the inside of the air filter 15, heats up after contacting the second heater 14, and continues to enter the air flow channel 11, where it is divided into two parts and contacts the evaporator 3, and then is discharged from the air outlet 7 at the upper part of the outer shell 1, thereby forming an air flow inside the outer shell 1; in this process, the mechanical valve in the water storage tank 2 9 opens the water inlet 8 to allow the water in the water tank 6 to flow into the water storage tank 2. When the liquid level in the water storage tank 2 reaches the rated line, the mechanical valve 9 closes the water inlet 8 through the principle of the float valve. At this time, the lower part of the evaporator 3 is immersed in the water in the water storage tank 2, and the water gradually penetrates upward in the fiber filter element through the capillary phenomenon. Under the action of the aforementioned airflow, the water on the evaporator 3 is evaporated and continuously discharged through the air outlet 7; at this time, the first heater 12 can be used to heat the water in the water storage tank 2, and the second heater 14 can be combined to heat the airflow. By increasing the temperature, the evaporation amount of water on the evaporator 3 is increased, thereby increasing the humidification amount.

[0037] When water needs to be added, water can be directly poured on the cover 10, and the water will flow into the water tank through the through holes on the cover 8. The cover 10 can also be opened to add water.

[0038] When there is no water in the water tank 6 and the water storage tank 2, the fan 4 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.
