Description

Technical Field

[0001] This invention belongs to the field of air conditioner technology, specifically relating to a fresh air air conditioner and its control method. Background Technology

[0002] Indoor air often contains dust and lint, microparticles invisible to the naked eye. Installing an air purifier requires an additional appliance, increasing power consumption. This not only takes up space but also results in noise and low efficiency. Furthermore, air purifier filters are consumables, further increasing living costs. Summary of the Invention

[0003] This invention provides a fresh air conditioner and its control method. The fresh air conditioner integrates air conditioning and air purification, and can automatically purify dust and other substances in the room air without the need for an additional air purifier.

[0004] This invention provides a fresh air air conditioner, comprising:

[0005] The housing has an air conditioning inlet on its top.

[0006] The ventilation component is housed in the housing and has an exhaust airflow path;

[0007] An air purification component, comprising a dust collection mesh and an electrostatic generator that causes the dust collection mesh to become electrostatically charged, the dust collection mesh covering the air inlet of the air conditioner and the exhaust air inlet of the exhaust airflow path, the electrostatic generator being mounted on the housing and close to the dust collection mesh.

[0008] When the fresh air conditioner is set to exhaust mode, the dust filter moves back and forth, causing the dust on the filter to be discharged outdoors through the exhaust airflow path.

[0009] In some embodiments, the dust collection net is a tensioned annular belt, with one side of the dust collection net being the mesh surface and the other side having clearance holes.

[0010] In some embodiments, the air purification assembly further includes a drive unit for driving the dust collection mesh to reciprocate. The drive unit includes a motor and a drive shaft and a driven shaft that respectively support both ends of the dust collection mesh. The motor is mounted on the housing, and the drive shaft is connected to the output end of the motor.

[0011] In some implementations, the electrostatic generator is located at the end of the housing away from the ventilation assembly.

[0012] In some embodiments, an air quality sensor is provided on the housing, located next to the air conditioning inlet.

[0013] In some implementations, the ventilation assembly also has a fresh air flow path, and the fresh air flow path and the exhaust air flow path share a duct to achieve ventilation. The fresh air flow path and the exhaust air flow path can be switched.

[0014] In some implementations, the ventilation assembly is equipped with a health filter, and when the ventilation assembly switches to the exhaust airflow path, the dust in the exhaust airflow path bypasses the health filter and is discharged outdoors.

[0015] In some implementations, the health filter is tilted so that when the ventilation assembly switches to a fresh air flow path, the air drawn into the fresh air flow path passes through the health filter.

[0016] A control method for a fresh air conditioner, wherein the fresh air conditioner is as described above, and the fresh air conditioner includes an air quality sensor mounted on its housing, and an air purification component further includes a drive unit for driving a dust collection screen to reciprocate, the drive unit including a motor and a drive shaft and a driven shaft respectively supporting both ends of the dust collection screen, the method includes the following steps:

[0017] Turn on the fresh air conditioner, and the air quality sensor will detect the PM2.5 levels in the air;

[0018] When the PM2.5 value in the air is greater than or equal to the set value in the program, the dust removal and cleaning program is started, the electrostatic generator is turned on, the fresh air air conditioner is adjusted to exhaust mode, the dust collection net is filled with static electricity, the motor drives the drive shaft to rotate, the dust collection net moves towards the exhaust air inlet in the exhaust airflow path, and the ventilation component uses maximum suction to discharge the dust on the dust collection net to the outside through the exhaust airflow path.

[0019] When the PM2.5 level in the air is less than or equal to the set value in the program, the electrostatic generator shuts off and the dust filter moves to its initial position.

[0020] The present invention provides a fresh air conditioner and its control method, which have the following beneficial effects:

[0021] When the fresh air conditioner is running and air purification is needed, the electrostatic generator activates, causing the dust collection screen to become statically charged. This static electricity attracts airborne dust, lint, and fine particles onto the screen. The screen, carrying the collected dust, moves to the exhaust inlet in the exhaust airflow path. The ventilation component generates suction, drawing the dust into the exhaust airflow path and discharging it outdoors. This invention can activate the air purification component based on air quality, simultaneously attracting airflow from the fresh air conditioner and trapping dust, lint, and fine particles, thus improving indoor air quality. It integrates air conditioning and air purification, automatically purifying indoor air without the need for a separate air purifier. Attached Figure Description

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0035] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0036] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0037] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this invention; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0038] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures.

[0039] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.

[0040] See also Figures 1 to 4 As shown, according to an embodiment of the present invention, a fresh air conditioner is provided, which includes a housing 1, an air exchange component 2, and an air purification component. An air inlet 101 is provided on the top of the housing 1; the air exchange component 2 is disposed in the housing 1 and has an exhaust airflow path 201; the air purification component includes a dust collection net 301 and an electrostatic generator 302 for aggregating the dust collection net 301 with static electricity. The dust collection net 301 covers the air inlet 101 and the exhaust air inlet of the exhaust airflow path 201. The electrostatic generator 302 is disposed on the housing 1 and close to the dust collection net 301; when the fresh air conditioner is adjusted to exhaust mode, the dust collection net 301 reciprocates, causing the dust on the dust collection net 301 to be discharged outdoors through the exhaust airflow path 201.

[0041] In this embodiment, when the fresh air conditioner is running and air purification is required, the electrostatic generator 302 activates, causing the dust collection net 301 to become electrostatically charged. Utilizing the electrostatic adsorption capacity, dust, lint, and microparticles floating in the air are adsorbed onto the dust collection net 301. The dust collection net 301, carrying the adsorbed dust, moves to the exhaust air inlet of the exhaust airflow path 201. The ventilation component 2 generates suction, adsorbing the dust into the exhaust airflow path 201 and discharging it outdoors. This invention can activate the air purification component based on air quality, adsorbing dust, lint, and microparticles in the air while the fresh air conditioner is intakeing, improving indoor air quality. It integrates air conditioning and air purification, automatically purifying indoor air without the need for an additional purifier.

[0042] See also Figure 5 As shown, the dust collection net 301 is a tensioned annular belt. One side of the dust collection net 301 is the mesh surface 311, and the other side of the dust collection net 301 is provided with clearance holes.

[0043] In one specific implementation, the dust collection mesh 301 has a double-layer structure, with the area of ​​the mesh surface 311 matching the area of ​​the clearance holes. In its initial position, the mesh surface 311 is positioned above the clearance holes. Air drawn in from the air conditioning inlet 101 falls onto the mesh surface 311. The mesh density of the mesh surface 311 ensures normal airflow from the air conditioning inlet 101 while preventing dust from being drawn into the interior of the fresh air conditioner. When dust on the mesh surface 311 needs to be expelled, the mesh surface 311 reciprocates to the exhaust inlet of the exhaust airflow path 201. The clearance holes allow the dust on the mesh surface 311 to be smoothly drawn into the exhaust airflow path 201.

[0044] See also Figure 6 As shown, the air purification component also includes a drive unit that drives the dust collection mesh 301 to reciprocate. The drive unit includes a motor 303 and a drive shaft 304 and a driven shaft 305 that support the two ends of the dust collection mesh 301 respectively. The motor 303 is mounted on the housing 1, and the drive shaft 304 is connected to the output end of the motor 303.

[0045] Specifically, since the dust collection net 301 is a tensioned annular belt, the drive shaft 304 and the driven shaft 305 keep the dust collection net 301 in a tensioned state. When the motor 303 works, the drive shaft 304 rotates, and the dust collection net 301 rolls while the driven shaft 305 also rotates, realizing the cyclic reciprocating motion of the dust collection net 301. The drive unit is provided to expand and flatten the dust collection net 301, driving the dust collection net 301 to reciprocate, ensuring that the air conditioner inlet 101 is covered by the dust collection net 301.

[0046] An electrostatic generator 302 is disposed on the end of the housing 1 furthest from the ventilation assembly 2. In this embodiment, a motor 303 is mounted on the end of the housing 1 closest to the ventilation assembly 2, and a driven shaft 305 is mounted on the other end of the housing 1 furthest from the ventilation assembly 2. The electrostatic generator 302 is disposed beside the driven shaft 305, enabling the electrostatic generator 302 to conduct static electricity to the dust collection mesh 301. This invention utilizes the principle of electrostatic adsorption, allowing the dust collection mesh 301 to adsorb dust, lint, and microparticles, preventing these particles from being drawn into the fresh air air conditioner.

[0047] An air quality sensor 4 is installed on the housing 1, located beside the air inlet 101 of the air conditioner. Specifically, the air quality sensor 4 is used to acquire air quality data. When the air quality does not meet the set value of the fresh air air conditioner, the electrostatic generator 302 is activated, causing the dust collection screen 301 to become statically charged.

[0048] See also Figure 7 and Figure 8 As shown, the ventilation component 2 also has a fresh air flow path 202. The fresh air flow path 202 and the exhaust air flow path 201 share a duct to achieve ventilation. The fresh air flow path 202 and the exhaust air flow path 201 can be switched.

[0049] The ventilation component 2 is equipped with a health filter 203. When the ventilation component 2 switches to the exhaust airflow path 201, the dust in the exhaust airflow path 201 avoids the health filter 203 and is discharged to the outside.

[0050] The health filter 203 is tilted so that when the ventilation component 2 switches to the fresh air flow path 202, the air drawn into the fresh air flow path 202 passes through the health filter 203.

[0051] In one specific implementation, after the ventilation component 2 is vertically installed in the housing 1, a first baffle and a second baffle are respectively provided at the top and bottom of the ventilation component 2. The first baffle and the second baffle have a first position and a second position respectively. When both the first baffle and the second baffle are in the first position, the ventilation component 2 opens the exhaust mode, and the air inlet and outlet in the exhaust airflow path 201 are in an open state. At this time, the ventilation component 2 exhausts air outward, and the airflow in the exhaust airflow path 201 bypasses the health filter 203 and is discharged from the pipe with dust. When both the first baffle and the second baffle are in the second position, the ventilation component 2 opens the fresh air mode, and the air inlet and outlet in the fresh airflow path 202 are in an open state. At this time, the ventilation component 2 draws air inward, and the airflow in the fresh airflow path 202 is drawn in from the pipe and passes through the health filter 203 to ensure that the drawn-in air is fresh.

[0052] In this embodiment, the present invention achieves integrated fresh air and exhaust through the ventilation component 2. The fresh air air conditioner shares a single duct for both inward air intake and outward air exhaust to achieve ventilation. In exhaust mode, the exhaust air does not need to pass through the health filter 203, thereby reducing the wear and tear on the health filter 203. Furthermore, the present invention, combined with the exhaust method of the ventilation component 2, allows dust on the dust collection screen 301 to be discharged outdoors without the need for additional structures, simplifying the operation process and improving the user experience.

[0053] A method for controlling a fresh air conditioner, wherein the fresh air conditioner is as described above, includes the following steps:

[0054] Turn on the fresh air conditioner, and the air quality sensor 4 will obtain information on PM2.5 levels in the air;

[0055] When the PM2.5 value B in the air is greater than or equal to the set value A in the program, the dust removal and cleaning program is started. The electrostatic generator 302 is turned on, the fresh air air conditioner is adjusted to exhaust mode, the dust collection net 301 is filled with static electricity, the motor 303 drives the drive shaft 304 to rotate, the dust collection net 301 moves towards the exhaust air inlet of the exhaust airflow path 201, and the maximum suction of the ventilation component 2 discharges the dust on the dust collection net 301 to the outside through the exhaust airflow path 201.

[0056] When the PM2.5 value B in the air is less than or equal to the set value A in the program, the electrostatic generator 302 is turned off and the dust collection net 301 moves to its initial position.

[0057] It will be readily understood by those skilled in the art that the aforementioned advantageous methods can be freely combined and superimposed without conflict.

[0058] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention. The above are merely preferred embodiments of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the protection scope of the present invention.
