Description

Technical Field

[0001] The invention belongs to the technical field of air conditioning, and more specifically, relates to an air purifier with a humidification function. Background Art

[0002] Air purifiers have functions such as filtering, sterilization and formaldehyde removal. Some air purifiers are also equipped with humidification water tanks to increase the humidification function, achieving humidification and purification in one. At present, some humidification-type air purifiers on the market achieve humidification by rotating the filter element and immersing it in water. This structure is complex and energy-intensive; another part of air purification and humidification equipment humidifies by forming a water curtain. Specifically, the bottom of the wet curtain assembly is immersed in the water in the water tank to absorb moisture, and then the rotation of the wet curtain assembly is controlled to fill the entire wet curtain with moisture, and then air is supplied by the fan. The wind discharged from the air outlet passes through the wet curtain, so that the moisture evaporates to achieve the humidification effect.

[0003] For the scheme of rotating the filter element to immerse in water to achieve humidification, it is impossible to start the humidification function or purification function separately, which makes it extremely inconvenient to use. For the scheme using the wet curtain assembly, the wet curtain assembly is mostly sealed at the air outlet and fixed. When the purification mode is started separately, the wet curtain assembly is still sealed at the air outlet, which will occupy a large part of the air outlet area of ​​the air outlet, making the air volume too small, the noise too loud, and the purification effect not obvious when the user uses the purification mode alone. In addition, the wind flowing through the wet curtain will also cause certain losses to the wet curtain, accelerate the aging of the wet curtain, and affect the service life of the wet curtain. Of course, various humidification assemblies with other structures have also appeared on the market to increase the humidification function of the air purifier, but due to their complex structure and large space occupation, the overall size of the air purifier is large, which is not only not conducive to transportation, but also occupies limited indoor space.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0020] In the claims, specification and the above drawings of the present invention, unless otherwise clearly defined, the terms "first", "second" or "third" are used to distinguish different objects, rather than to describe a specific order. Unless otherwise specified, other directional words, such as "vertical", "clockwise", "counterclockwise", etc., indicating directions or positional relationships are based on the directions and positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, so it cannot be understood as limiting the specific protection scope of the present invention. In the claims, specification and the above drawings of the present invention, unless otherwise clearly defined, the terms "fixed connection" or "fixed connection" should be understood in a broad sense, that is, any connection method without a displacement relationship and relative rotation relationship between the two, that is, including non-detachable fixed connection, detachable fixed connection, integrated connection and fixed connection through other devices or elements. In the claims, specification and the above drawings of the present invention, the terms "including", "having" and their variations are used, and the intention is to "include but not limited to".

[0021] Please also read Figures 1 to 8, the air purifier with humidification function provided by the present invention is now described. The air purifier with humidification function includes a shell 1, a fixing component 3, a drainage fan 8, a switching component 4, a humidification component 5 and a purification component 2. The shell 1 has an installation cavity inside, and the shell 1 is also provided with an air inlet 101 and an air outlet respectively connected to the installation cavity; the fixing component 3 is arranged in the installation cavity and connected to the shell 1, and the fixing component 3 is respectively formed with an installation space 303 and a purification space 304 and a humidification space 305 respectively connected to the installation cavity, the purification space 304 and the humidification space 305 are respectively connected to the air outlet, and the installation space 303 is connected to the air inlet 101; The induced draft fan 8 is arranged in the installation space 303, and is used to suck external air into the installation space 303 along the air inlet 101; the switching component 4 is connected to the fixed component 3, and the switching component 4 has a purification state in which the installation space 303 is connected only with the purification space 304, a humidification state in which the installation space 303 is connected only with the humidification space 305, and a compatible state in which the installation space 303 is connected to the purification space 304 and the humidification space 305 at the same time; the humidification component 5 is arranged in the humidification space 305 and is connected to the fixed component 3; the purification component 2 is arranged in the installation cavity, and is used to filter the air.

[0022] The air purifier with humidification function provided by the present invention is compared with the prior art. Different partitions are set on the fixed component 3, and the partitions are interconnected. Therefore, the introduction of airflow is achieved by only one drainage fan 8, and the corresponding partition connection or blocking can be controlled by setting the switching component 4 to change the flow direction of the airflow. The switching component 4 is controlled to switch between the purification state, the humidification state and the compatible state to achieve purification, humidification or humidification purification of the air. The present invention not only avoids the problem that the humidification component 5 is set at the air outlet when a single air outlet is used, resulting in too small air volume when the purification mode is used alone, but also does not need to set the drainage fan 8 for the humidification mode and the purification mode respectively, and does not need to set the purification channel, the humidification channel and the corresponding opening component separately, which simplifies the overall structure, is conducive to realizing the rational layout of the space, reducing the overall volume of the air purifier, facilitating transportation, and reducing the occupied space.

[0023] Optionally, the air purifier with humidification function further includes a humidification fan 503 disposed in the humidification space 305, and the humidification fan 503 is used to introduce the airflow in the installation space 303 into the humidification module. Since the drainage fan 8 has introduced the external air into the installation space 303, and the installation space 303 is a relatively closed space, the pressure in the installation space 303 is relatively large, and the humidification fan 503 can introduce the airflow into the humidification module without excessive power, so the humidification fan 503 is relatively small in size and does not take up too much space.

[0024] Optionally, the purification component 2 can be arranged at the air inlet end of the induced draft fan 8, and the air first passes through the purification component 2 before entering the installation space 303; it can also be arranged in the purification space 304. In the purification state, the air is filtered by the purification module and then discharged from the outlet.

[0025] Optionally, the purification component 2 may be a high-efficiency air filter.

[0026] As a specific embodiment of the housing 1, please refer to Figure 1 The housing 1 comprises a shell with an opening on the top and a breathable cover arranged on the top of the shell, an air outlet is arranged on the breathable cover, and an air inlet 101 is also arranged on the side wall of the shell.

[0027] Optionally, the shell includes a main body with an opening on one side and a cover plate covering the opening of the main body, and the air inlet 101 is provided on the cover plate.

[0028] Optionally, the air outlet corresponding to the purification space 304 has a guide surface that is inclined toward the humidification space 305 in sequence, so that the purified airflow is discharged obliquely toward one side of the humidification component 5. The humidified airflow flows vertically upward when corresponding to the air outlet of the humidification space 305. In the compatible state, the humidified airflow flows vertically upward, and the purified airflow flows toward the side above the humidification component 5, thereby mixing with the humidified airflow to form a cross mixed flow, which not only improves the humidification speed, but also realizes the circulation of the humidified airflow in the space.

[0029] It should be noted that Figure 3 The switching component 4 is in the humidification state.

[0030] In some embodiments, see Figure 3 The fixing assembly 3 includes a fixing plate 301 and a partition 302. The fixing plate 301 is arranged in the installation cavity and connected to the shell 1. The fixing plate 301 divides the installation cavity into an air inlet cavity and an air outlet cavity that are independent of each other. The fixing plate 301 is also provided with an air vent connecting the air inlet cavity and the air outlet cavity; the partition 302 is connected to the fixing plate 301 and is located in the air outlet cavity. The partition 302 divides the fixing plate 301 from the inside to the outside into an inner installation area and an outer installation area. The air vent is opened in the inner installation area. The partition 302 is provided with a switching opening that connects the inner installation area with the outer installation area. The purification space 304 and the installation space 303 are both located in the inner installation area, and the humidification space 305 is located in the outer installation area.

[0031] The partition 302 is connected to the fixed plate 301, and divides the fixed plate 301 into an inner installation area and an outer installation area. This structure is simple and occupies a small space. The mounting plate can not only provide a mounting position for the humidification component 5, the purification component 2 and the drainage fan 8, but also divide the mounting cavity into an air inlet cavity and an air outlet cavity, thereby avoiding the phenomenon of all components being piled up in one cavity and causing a disordered layout. In addition, the components are installed on the partition plate, which also avoids the problem of internal components being damaged after being acted upon by external forces.

[0032] Optionally, the purification component 2 is arranged in the air inlet cavity. After the purification component 2 is used for a period of time, it needs to be replaced. The purification component 2, the humidification component 5, and the switching component 4 are arranged in different chambers, and the housing 1 can be opened for replacement, which avoids affecting other components and improves the replacement efficiency.

[0033] Optionally, the partition 302 may be enclosed with the mounting plate to form a closed structure with only the air inlet 101 and the air outlet retained, or may be respectively abutted against the mounting plate and the housing 1 to form a closed structure with only the air inlet 101 and the air outlet retained.

[0034] In some embodiments, see Figure 3 The switching component 4 includes a driver 401, a first baffle 402 and a second baffle 403. The driver 401 is arranged in the installation cavity; the first baffle 402 is connected to the driver 401 and is located in the purification space 304; the second baffle 403 is connected to the driver 401 and is located in the humidification space 305. The driver 401 is used to drive the first baffle 402 and the second baffle 403 to move to achieve switching between the purification state, the humidification state and the compatible state.

[0035] The driver 401 controls the first baffle 402 and the second baffle 403 to rotate or slide, thereby realizing switching between the purification state, the humidification state and the compatible state, without the need for manual application of external force to drive, which is more convenient and labor-saving.

[0036] Optionally, the driver 401 can be a motor, and the first baffle 402 and the second baffle 403 are both connected to the same motor, or are respectively connected to corresponding motors. The driver 401 can also be a pneumatic or hydraulic telescopic member, and the first baffle 402 and the second baffle 403 are respectively connected to corresponding telescopic members, or the telescopic member has two telescopic ends with different directions, and the first baffle 402 and the second baffle 403 are arranged at the two telescopic ends in a one-to-one correspondence. In some embodiments, see Figures 3 to 8 The humidification component 5 includes a water tank and an atomizer 505. The water tank is arranged in the humidification space 305 and connected to the fixed component 3. The water tank has an atomization opening; the atomizer 505 is inserted in the atomization opening and connected to the water tank. The atomizer 505 is used to atomize the water in the water tank.

[0037] The water in the water tank is atomized by the atomizer 505, and the atomized water vapor is discharged from the installation cavity to increase the humidity of the air. Compared with the solution of setting a wet curtain assembly, this embodiment can further reduce the water mist particles, make the water mist and air fully mixed, and increase the humidity of the indoor air.

[0038] Specifically, the water storage tank is connected to the air outlet.

[0039] Optionally, the atomizer 505 is conductively connected to a power source, and may also have its own battery.

[0040] In some embodiments, see Figures 3 to 8 The water storage tank includes an upper water tank 501 and a lower water tank 502. The lower water tank 502 is arranged in the humidification space 305 and connected to the fixed component 3; the upper water tank 501 is arranged in the lower water tank 502, and the atomization opening is opened in the upper water tank 501 or the lower water tank 502.

[0041] The upper water tank 501 is used as a container for holding water. When the atomization opening is opened in the upper water tank 501, the atomizer 505 is connected to the upper water tank 501 to atomize the water in the upper water tank 501 and discharge it to the outside. The lower water tank 502 is used as a bracket connected to the fixing component 3 to provide support for the upper water tank 501. The upper water tank 501 is placed in the lower water tank 502 to facilitate the placement of the upper water tank 501. When the lower atomization opening is opened in the lower water tank 502, the atomizer 505 is connected to the lower water tank 502 to atomize the water in the lower water tank 502. At this time, the upper water tank 501 is provided with a diversion port connected to the lower water tank 502, and a sealing plug 5012 is provided in the diversion port. The lower water tank 502 is provided with a plug 508 corresponding to the diversion port and plugged with the sealing plug 5012. After the upper water tank 501 is placed in the lower water tank 502, the plug 508 applies force to the sealing plug 5012, and the water in the upper water tank 501 enters the lower water tank 502. On the contrary, after the upper water tank 501 is taken out, the sealing plug 5012 is no longer subjected to force and the diversion port is sealed. Water can be directly poured into the upper water tank 501, and the water flows into the lower water tank 502 through the diversion port, or the upper water tank 501 can be taken out, and after the upper water tank 501 is filled with water, the upper water tank 501 is placed in the lower water tank 502. The scheme in this embodiment can facilitate the placement of the upper water tank 501, not only can fast and convenient water filling be achieved, but also can be convenient for the container containing water.

[0042] Optionally, when the atomizer 505 is disposed in the lower water tank 502, an atomizing tube is inserted into the upper water tank 501, the atomizing tube penetrates into the lower water tank 502 and corresponds to the atomizer 505, so that the atomized water vapor is discharged outward along the atomizing tube.

[0043] In some embodiments, see Figure 4 and Figure 7The humidifying component 5 also includes a liquid level detector, a controller and a prompter. The liquid level detector is arranged in the water tank and is used to detect the water level in the water tank; the controller is respectively communicated with the liquid level detector; the prompter is communicated with the controller for alarm information.

[0044] The liquid level detector is used to detect the water level in the water tank. When the liquid level detector detects that the water level in the water tank is lower than the minimum water level value, a water-adding signal is generated. The controller controls the indicator to issue a water-adding alarm according to the water-adding signal.

[0045] Optionally, the prompter may be one or more of a buzzer, a warning light, and a display.

[0046] Optionally, the liquid level detector may be a liquid level sensor.

[0047] As a specific implementation of the liquid level detector, please refer to Figure 7 When the atomizer 505 is arranged in the upper water tank 501, the liquid level detector includes a float 504 arranged in the water tank and a sensor arranged on the atomizer 505, and also includes a limit cylinder 509 arranged in the upper water tank 501. The limit cylinder 509 is provided with a water hole. The sensor is used to detect the distance between it and the float 504 and communicate with the controller.

[0048] As the water level changes, the float 504 moves up and down in the limit tube 509. When the sensor detects that the distance between the float 504 and the sensor is less than the minimum water level value, a water-adding signal is generated. The controller controls the indicator to issue a water-adding alarm according to the water-adding signal.

[0049] Optionally, the limiting cylinder 509 can be arranged at the bottom of the upper water tank 501 , or can be connected to the cover plate of the upper water tank 501 and inserted into the upper water tank 501 .

[0050] As another specific implementation of the liquid level detector, please refer to Figure 4 When the atomizer 505 is arranged in the lower water tank 502, the liquid level detector is arranged in the lower water tank 502, including a float and a detection sheet arranged at the bottom of the lower water tank 502, the detection sheet is communicatively connected with the controller, and is used to detect the distance between the floats.

[0051] In some embodiments, see Figures 4 to 6A mounting hole is provided at the bottom of the upper water tank 501, and the humidifying assembly 5 also includes a guide tube 5011 and an atomizing hood 507. The guide tube 5011 is inserted into the mounting hole, and the guide tube 5011 has a drainage portion located below the upper water tank 501 and a guide portion located inside the upper water tank 501; the atomizing hood 507 is provided on the top of the guide tube 5011 and has an exhaust passage that passes through in the up and down directions, and the atomizing hood 507 includes a connecting portion 5071 connected to the guide tube 5011 and an exhaust portion 5072 connected to the top of the connecting portion 5071, and at least two opposite surfaces of the upper portion of the exhaust portion 5072 are compressed to form a structure with a conical longitudinal section. The atomized water mist flows along the guide tube 5011, and flowing along the guide tube 5011 can make the water mist discharged more concentratedly, thereby increasing the airflow strength. In addition, since the atomizing hood 507 is arranged on the top of the guide tube 5011 and has a conical longitudinal section, it can not only further increase the airflow strength, so that the airflow can flow to a region away from the atomizer 505 after being discharged, but the conical exhaust part 5072 can also block large particles of water mist in the atomizing hood 507, and fall into the guide tube 5011 to be further atomized.

[0052] Optionally, the exhaust portion 5072 has a circular bottom and a long strip top with a uniform transition from bottom to top.

[0053] Optionally, the exhaust portion 5072 is a conical structure with a diameter gradually decreasing from bottom to top.

[0054] In some embodiments, see Figure 4 A drainage plate is provided in the atomizing hood 507 . The drainage plate is distributed in a spiral shape around the axis of the atomizing hood 507 and is connected to the inner wall of the atomizing hood 507 .

[0055] After the atomized water vapor enters the atomizing hood 507, it flows along the drainage plate, which can prevent the large water droplets that are not fully atomized from being sprayed out, so that the large water droplets cannot be fully mixed with the air and fall quickly under the action of gravity, causing water to accumulate in the housing 1 and / or nearby areas, affecting the user's experience. In some embodiments, see Figure 7 The upper water tank 501 includes a mounting seat 5013, a box body 5014 and a coupling module 506. The mounting seat 5013 is arranged in the lower water tank 502 and is provided with a mounting hole; the box body 5014 is connected to the mounting seat 5013, the atomization opening is opened in the box body 5014, and the atomizer 505 is connected to the box body 5014; the coupling module 506 includes a coupler 5061 connected to the atomizer 505 and a connector 5062 connected to the lower water tank 502, the coupler 5061 is inserted in the mounting hole, and is plugged into and matched with the connector 5062.

[0056] The box 5014 is fixedly connected to the mounting seat 5013, and the atomizer 505 is connected to the box 5014 for atomizing the water in the box 5014. The atomizer 505 is also connected to a coupler 5061. When the upper water tank 501 is placed in the lower water tank 502, the coupler 5061 and the connector 5062 are plugged and matched to form a conductive path for the atomizer 505. The solution in this embodiment can conveniently take and place the upper water tank 501, and the conductive structure of the atomizer 505 is more simply energized, which is not only quick to fill with water, but also convenient to clean the box 5014.
