In the related art, a fresh air conditioner indoor unit includes an indoor unit and a ventilation duct. The ventilating duct extends from indoor to outdoor, and the indoor unit is used for pressurizing and leading outdoor air into the indoor through the ventilating duct. Generally, when installing a ventilation duct, an installation hole needs to be formed in an indoor wall.

From the angle of indoor pleasing to the eye, the aperture of mounting hole is difficult too big, also leads to the aperture of air pipe to be difficult to further increase. Under the condition, the air inlet quantity of the indoor unit of the fresh air conditioner is increased by increasing the indoor unit power in the related art. However, the increase of the power of the indoor unit causes the defects of large working noise of the indoor unit or overlarge volume of the indoor unit, and the use experience of the indoor unit of the fresh air conditioner is influenced. Therefore, the difficulty in increasing the air intake is high by adopting the fresh air conditioner indoor unit provided in the related technology, and the use experience of the fresh air conditioner indoor unit is difficult to be considered in many aspects.

Based on the above problems, the embodiment of the present disclosure provides a fresh air conditioner indoor unit, and a control method and device for the fresh air conditioner indoor unit, where the fresh air conditioner indoor unit solves the defect that the air intake is difficult to increase in the related art on the premise of giving consideration to user experience, so as to optimize the user experience. The fresh air conditioner indoor unit provided by the embodiment of the disclosure can be selected as an air conditioning system with a fresh air function.

Fig. 1 is a schematic view of a usage scenario of a fresh air conditioner indoor unit according to an exemplary embodiment. As shown in fig. 1, the fresh air conditioning indoor unit includes a ventilation duct 100, a fresh air blower 200, a duct blower 300, and a controller 500.

The ventilation duct 100 includes a first end 110 located indoors and a second end 120 located outdoors, and communicates the indoors and outdoors through the first end 110 and the second end 120. Alternatively, a mounting hole 810 is formed on the wall 800, and the ventilation duct 100 is disposed through the mounting hole 810.

The fresh air blower 200 is installed indoors and is connected to the first end 110 of the ventilation duct 100. Optionally, the fresh air fan 200 is an air conditioner internal unit with a fresh air function. Illustratively, the fresh air blower 200 includes a body 210, an air compressor 220, and a filter assembly 230.

The main body 210 is formed with an installation cavity 211 and a fresh air outlet 2111 communicated with the installation cavity 211. An air compressor 220 is mounted within the mounting cavity 211 and communicates with the first end 110 of the ventilation duct 100. The airflow is directed into or out of the ventilation duct 100 from the first end 110 by the air compressor 220. The filter assembly 230 is positioned within the mounting cavity 211 or within the vent conduit 100 and is disposed over the first end 110. Accordingly, the airflow entering the first end 110 from the ventilation duct 100 is discharged from the air outlet 2111 of the mounting cavity 211 after passing through the filter assembly 230. The implementation manner of the filtering assembly 230 is not limited, for example, a hepa (high Efficiency particulate air) filter cartridge.

The duct fan 300 is disposed inside the ventilation duct 100. At this time, the duct fan 300 and the air compressor 220 in the fresh air fan 200 cooperate to pressurize the airflow, so that the airflow passes through the ventilation duct 100 from the outdoor to the indoor. Optionally, the distance between the fan blade of the duct fan 300 and the inner wall of the ventilation duct 100 is greater than or equal to 1mm, so as to ensure the normal operation of the duct fan 300, avoid the duct fan 300 occupying too much space in the ventilation duct 100, and ensure the ventilation duct 100 to be smooth.

The controller 500 is installed in the body 210 of the fresh air fan 200 and is used for controlling the start and stop of the pipeline fan 300 and the fresh air fan 200 according to a fresh air noise control instruction; or the control device is used for controlling the starting, stopping and steering of the pipeline fan 300 and the fresh air fan 200 according to the blockage removal control instruction. Accordingly, the duct fan 300 and the fresh air fan 200 can independently operate. Further, one of the duct fan 300 and the fresh air fan 200 may be selected to operate according to the fresh air noise control instruction.

Wherein, new trend noise control command has multiple acquisition mode.

In the first mode, the fresh air noise control command is generated according to a fresh air noise mode selected by a user and a corresponding relation between a preset fresh air noise mode and a noise control strategy.

Wherein, the new trend noise mode includes that the new trend falls the mode of making an uproar, the new trend does not fall the mode of making an uproar, does not have the new trend and falls the mode of making an uproar. The noise control strategy comprises one or more of the following strategies: and controlling the pipeline fan 300 and the fresh air fan 200 to be started. And a second strategy is to control the pipeline fan 300 to be closed and the fresh air fan 200 to be opened. And a third strategy is to control the pipeline fan 300 to be started and the fresh air fan 200 to be closed. The corresponding relation between the preset fresh air noise mode and the noise control strategy comprises the following steps: the fresh air noise reduction mode corresponds to a strategy I, the fresh air noise reduction free mode corresponds to a strategy II, and the fresh air noise reduction free mode corresponds to a strategy III.

In the first mode, a fresh air noise reduction button and a fresh air noise reduction button are arranged on a remote controller for inputting information of a fresh air conditioner or an APP (application) matched with the fresh air conditioner by a mobile terminal. The user selects different noise reduction modes by activating different buttons. Or, the APP of the remote controller or the mobile terminal may be provided with a new air mode and a noise reduction button, and the remote controller or the mobile terminal may determine the new air noise mode that the user wants to select according to the operation of the user on the new air mode and the noise reduction button, for example, if the user presses the new air button but does not press the noise reduction button, the user is considered to select the new air noise reduction mode, and if the user presses the new air button and the noise reduction button, the user is considered to select the new air noise reduction mode, and if the user presses the noise reduction button but does not press the new air button, the user is considered to select the new air noise reduction mode. And then, determining a corresponding noise control strategy according to the preset corresponding relation between the fresh air noise mode and the noise control strategy, and sending the determined noise control strategy to the controller 500 in the fresh air conditioner indoor unit. After receiving the noise control strategy, the controller 500 generates a fresh air noise control command according to the noise control strategy.

And in the second mode, a fresh air noise control instruction is determined according to a fresh air control strategy. The fresh air control strategy is determined according to indoor user information. Moreover, the fresh air control strategy is the same as that in the first mode, and is not described herein again.

In a second approach, the user information includes: a number of users and/or a user status, the user status including a quiet status and an active status. Wherein, the quiet state means that the user does not perform the movement of the body with a large amplitude within a predetermined time. For example: the user is in sleeping, resting, learning and other states. The active state refers to a user's body moving by a large magnitude for a predetermined time. For example: walking back and forth, playing games, sports, etc.

In the mode, the fresh air demand is determined according to the number of users, and the noise reduction demand is determined according to the state of the users. And then, determining a noise control strategy according to the fresh air demand and the noise reduction demand.

Specifically, if the number of users is greater than a preset number threshold and the user status is in the quiet status, the policy one is executed. At this time, the fresh air extension 200 and the duct fan 300 work simultaneously to meet the requirement of the user for the fresh air demand.

And if the number of the users is less than the number threshold and the user state is the active state, executing the strategy two. At this time, only the fresh air blower 200 operates. The duct fan 300 is disposed inside the ventilation duct 100, and is limited by the inner diameter of the ventilation duct 100, and the size and power of the duct fan 300 are not easily too large. When the power of the fresh air fan 200 is greater than the power of the pipeline fan 300, the fresh air fan 300 is controlled to work under the condition that the user is insensitive to noise, so that the requirement of the user on fresh air ventilation volume is met more easily.

And if the number of the users is less than the number of people threshold and the user state is the quiet state, executing the strategy three. At this time, only the duct fan 300 operates. The duct fan 300 is disposed far from the first end 110 of the ventilation duct 100, so that the operating noise of the duct fan 300 is less than that of the fresh air fan 200. At this moment, adopt pipeline fan 300 work, both satisfied user's new trend demand of taking a breath, also avoided the user to receive noise interference.

Compared with the fresh air conditioner indoor unit in the related art, the fresh air power of the whole fresh air conditioner indoor unit is improved by adding the pipeline fan 300, and the air inlet volume is further increased. In addition, the duct fan 300 is disposed in the ventilation duct 100, so that the whole indoor unit of the fresh air conditioner is compact in structure, and does not need to add any equipment directly exposed outdoors. Also, the duct fan 300 is disposed proximate the second end 120 opposite the first end 110. Preferably, the duct fan 300 is disposed in a portion of the ventilation duct 100 located outdoors. By adopting the mode, the noise caused by the work of the pipeline fan 300 is prevented from influencing a user, and the user experience is guaranteed.

Fig. 2 is a schematic view of a usage scenario of a fresh air conditioner indoor unit according to another exemplary embodiment. As shown in fig. 2, the fresh air conditioner indoor unit further includes an identification component 400 disposed indoors. Optionally, the identification component 400 is mounted within the fuselage 210 of the fresh air blower 200.

The identification component 400 is used to identify user information indoors. Optionally, the identification component 400 includes, but is not limited to: camera subassembly, heat release infrared sensor, radar subassembly.

When the identification assembly 400 includes a camera assembly, the identification assembly 400 acquires images at a set frequency. At this time, the recognition component 400 recognizes the number of users and/or the user status based on the acquired image. The number of users is determined, for example, by recognition of an image of a particular object (e.g., head, limbs), and the user state is determined by recognition of the user's pose.

When the recognition assembly 400 includes a pyroelectric infrared sensor (e.g., a thermopile sensor), the recognition assembly 400 can receive infrared rays radiated by a user himself/herself, and then acquire an infrared image from the received infrared rays. The number of users is determined by recognition of the infrared image.

When the recognition component 400 includes a radar component (e.g., a millimeter wave radar), the recognition component 400 transmits a detection signal at a set frequency and receives the detection signal reflected back by the target object. The recognition component 400 obtains the distribution of different target objects relative to the recognition component 400 according to the received detection signal, and further determines the number of users.

In the embodiment of the present disclosure, the specific number of the identification members 400 and the arrangement position of the identification members 400 on the main body 210 of the fresh air blower 200 are not limited.

The controller 500 receives user information identified by the identification component 400 to determine a noise control strategy. Of course, the controller 500 may also obtain the user information in other ways. For example, the controller 500 is communicatively coupled to a wearable device of the user and receives user information transmitted by the wearable device.

In another embodiment of the disclosure, the identification component is in communication connection with the server, and after acquiring the user information, the identification component sends the user information to the server, and the server determines the noise control strategy according to the user information and sends the determined noise control strategy to the controller of the fresh air conditioner indoor unit.

The fresh air conditioner indoor unit provided by the embodiment of the disclosure controls the fresh air fan 200 and the pipeline fan 300 to work according to different application scenes through the matching of the identification component 400 and the controller 500, improves the intelligent degree of the fresh air conditioner indoor unit, considers the requirements of users on the air intake and the air conditioner working noise in two aspects, and optimizes the user experience.

In one embodiment, in order to keep the ventilation duct 100 open, the indoor unit of the fresh air conditioner further has a function of clearing the second end 120. Specifically, the controller 500 controls the start, stop and turning of the pipeline fan 300 and the fresh air fan 200 according to the blockage removal control instruction.

In this way, by controlling the direction of rotation of the duct fan 300 and/or the fresh air fan 200, the airflow from the indoor to the outdoor through the ventilation duct 100 is made. Accordingly, the second end 120 is cleared by the impingement of the airflow. Optionally, the controller 500 controls at least one of the duct fan 300 and the fresh air fan 200 to operate.

The blockage clearing control instruction has multiple generation modes:

optionally, the blockage clearing control instruction is generated periodically according to a pre-stored time trigger condition. The time trigger condition is according to a preset time interval (e.g., one week, two weeks, one month, etc.). In this way, regular clearing of the blockage is achieved.

Optionally, the blockage removal control instruction is generated within a set time length after the fresh air fan 200 and the pipeline fan 300 finish working according to the fresh air noise control instruction. For example, the blockage removal work is performed after the fresh air fan 200 and the duct fan 300 perform fresh air work each time, so that the ventilation duct 100 is ensured to be smooth.

Optionally, the blockage clearing control instruction is generated according to blockage clearing control information acquired by an information input component of the fresh air conditioner indoor unit. The information input component can be selected as a remote controller matched with the fresh air conditioner indoor unit, a control panel matched with the fresh air conditioner indoor unit or an application program installed on terminal equipment matched with the fresh air conditioner indoor unit, and can also be selected as a voice recognition component in the fresh air conditioner indoor unit and the like. The specific input mode can be key input, character input or voice input. In this way, the fresh air conditioner indoor unit can acquire the blockage clearing control information input by a user.

Optionally, the blockage clearing control instruction is generated according to a monitoring value obtained by the pressure monitoring component 600 arranged in the ventilation duct 100 and a preset monitoring threshold. Fig. 3 is a schematic view of a usage scenario of a fresh air conditioner indoor unit according to another exemplary embodiment. As shown in fig. 3, the indoor unit of the fresh air conditioner further includes a pressure monitoring assembly 600 for detecting the air pressure in the ventilation duct 100, and the function of clearing the blockage at the second end 120 is realized by the cooperation of the pressure monitoring assembly 600.

The pressure monitoring assembly 600 is disposed inside the ventilation duct 100. Optionally, the pressure monitoring assembly 600 is disposed between the duct fan 300 and the second end 120, or the pressure monitoring assembly 600 is disposed between the duct fan 300 and the first end 110.

Optionally, the pressure monitoring assembly 600 is used to detect absolute air pressure or relative air pressure within the ventilation duct 100. The absolute air pressure is the actual air pressure within the ventilation duct 100. The relative air pressure is a difference value between an actual air pressure in the ventilation duct 100 before and during operation of the fresh air blower 200 and/or the duct blower 200 (the rotation direction of the duct blower 200 is to introduce air from the outside to the inside). The influence of weather factors and the like on the air pressure in the ventilation pipeline can be avoided by monitoring the relative air pressure, and the monitoring accuracy is improved.

Optionally, the pressure monitoring component 600 is configured to obtain the monitoring value after the fresh air fan 200 and/or the duct fan 300 starts to operate for a set time (e.g., 5s, 10s, 15s, etc.). After a set time, the fresh air fan 200 and/or the duct fan 300 operate stably, and at this time, the data monitored by the pressure monitoring assembly 600 is not affected by the operation stability of the fan, and the air pressure condition in the ventilation duct 100 is faithfully reflected.

And, pressure monitoring subassembly 600 still with controller 500 electric connection, controller 500 receives the monitoring value that pressure monitoring subassembly 600 monitored to under the monitoring value is greater than or equal to the condition of predetermineeing the monitoring threshold value, control pipeline fan 300 counter-rotation to lead the air current outdoor from indoor, and then act on second end 120 through the air current, reach the clear purpose stifled of second end 120.

In addition, the controller 500 controls the duct fan 300 to operate in a constant speed manner or to operate in a variable speed manner. The speed change mode is adopted to enable the airflow to act on the blocking object on the second end 120 with different force, so as to achieve the effects of scouring and oscillation, and improve the blockage clearing efficiency.

In one embodiment, the fresh air conditioning indoor unit for the embodiment of the present disclosure further includes a shielding component 700 connected to the second end 120, and the shielding component 700 prevents impurities from blocking the second end 120.

The connection portion 710 is used to connect with the ventilation duct 100, and the blocking portion 720 is connected with a portion of the connection portion 710 far away from the ventilation duct 100.

Alternatively, the inner hollow of the connection part 710 is formed as the first cavity 711. The first cavity 711 has a first opening 711a and a second opening 711b at two ends thereof, which are disposed opposite to each other. The connecting portion 710 further includes a sidewall 712, and the sidewall 712 connects the first opening 711a and the second opening 711b, respectively, and is disposed around the first cavity 711. The second opening 111a is connected to the ventilation duct 100, and the connection portion 710 is provided with a vent 713 communicating with the first cavity 711.

When the connection part 710 is connected to the ventilation duct 100, the first cavity 711 communicates with the ventilation duct 100. At this time, the airflow outside the shielding assembly 700 sequentially enters the ventilation duct 100 through the vent 713 and the first cavity 711.

In this way, the portion of the connection portion 710 other than the ventilation hole 713 plays a role in shielding, and besides shielding impurities, the connection portion 710 can also prevent fresh air caused by outdoor wind from flowing backward into the ventilation duct 100. Moreover, the connection part 710 effectively avoids the condensation phenomenon in the ventilation duct 100 caused by the backflow of cold air in the low-temperature and strong-wind weather.

The blocking portion 720 is disposed at the first opening 711a and is connected to the sidewall 712. Also, the size of the blocking portion 720 is larger than the size of the first opening 711a to block the first opening 711 a. In the use state of the shutter assembly, the first opening 711a of the connecting portion 710 is positioned above the second opening 711 b. In this way, the shielding portion 720 plays a role of shielding, and prevents solid impurities, rain water, snow water, and the like from entering the ventilation duct 100. Optionally, the edge of the shielding portion 720 exceeds the connecting portion 710, and at this time, rainwater or snow water directly slides along the edge of the shielding portion 720, so as to prevent the rainwater or snow water from flowing along the connecting portion 710 and further flowing back into the ventilation duct 100 through the ventilation hole 713.

In the disclosed embodiment, the vent 713 has a variety of implementations, which are described below in conjunction with the figures.

Fig. 5-1 is a schematic diagram of a structure of a connection portion shown according to an exemplary embodiment. As shown in fig. 2, the first opening 711a of the connecting portion 710 has a first edge 710a, and the second opening 711b has a second edge 710 b. Also, portions of the first edge 710a and/or the second edge 710b are recessed to form vents 713 (shown only as having a partial recess at the first edge 710a in fig. 5-1).

After the shutter assembly 700 is coupled to the ventilation duct 100 (not shown in fig. 5-1), the first edge 710a and the second edge 710b are upper and lower edges of the coupling portion 710, respectively. At this time, since the first edge 710a and/or the second edge 710b are/is recessed, a gap, that is, the vent 713, is formed between the connection 710 and the shielding portion 720 (not shown in fig. 5-1), and/or between the connection 710 and an edge of the ventilation duct 100. In this way, the shielding effect of the connecting part 710 is enhanced, and the backflow of fresh air or cold air is avoided.

Fig. 5-2 is a schematic structural view of a connection portion shown according to another exemplary embodiment. As shown in fig. 5-2, the first opening 711a of the connecting portion 710 has a first edge 710a, and the second opening 711b has a second edge 710 b. The vent 713 is disposed on the sidewall 712 between the first edge 710a and the second edge 710 b.

Alternatively, as shown in fig. 5-2, the vent holes 713 are arranged in the circumferential direction of the first cavity 711, or the vent holes 713 are arranged in the axial direction of the first cavity 711, or the vent holes 713 are uniformly arranged on the connecting portion 710. The radial cross-sectional shape of the vent 713 is not particularly limited, and may be, for example, circular, oval, square, or the like. In this way, the connection 710 forms a screen-like structure, in which case the flow rate of the air flow passing through the connection 710 can be increased.

Fig. 6 is a schematic structural view of a connection part shown according to another exemplary embodiment. As shown in fig. 6, a first connecting structure 714 is disposed on the connecting portion 710, and the first connecting structure 714 is used for detachable connection with the ventilation duct 100. In this way, the shutter assembly 700 is easily installed and removed, reducing assembly maintenance costs.

Fig. 7 is a partial structural schematic view of a fresh air conditioning indoor unit according to another exemplary embodiment. As shown in fig. 7, the side wall 712 of the connection portion 710 is formed in a funnel shape gradually decreasing from the first opening 711a to the second opening 711 b.

At this time, the liquid drops (such as rain, snow, or condensation) attached to the side wall 712 are more likely to fall directly by gravity, and are difficult to continuously slide along the connection portion 710, thereby preventing the liquid from flowing backward to the ventilation duct 100 through the ventilation holes 713. Optionally, the angle of the connecting portion 710 to the vertical direction is 10 ° to 70 °.

And, the shielding portion 720 forms a funnel shape gradually expanding toward the connection portion 710. At this time, the outer side surface of the shielding portion 720 is inclined downward. In this way, rain and snow, foreign substances, or the like are less likely to adhere to the shielding portion 720, and the protection of the ventilation duct 100 by the shielding member 700 is further enhanced.

In summary, the shielding assembly 700 according to the embodiment of the present disclosure provides a vent 713 through the connection portion 710, so that the airflow enters the ventilation duct 100 through the vent 713 and one end in sequence. The part that does not set up ventilation hole 713 through connecting portion 710 has played the effect of sheltering from, effectively shelters from impurity entering air pipe to the problem that the new trend flows backward and the refrigerated air flows backward leads to the condensation has been solved.

Also, in the related art, the second end 120 of the ventilation duct 100 is disposed downward to avoid clogging by debris. However, this way the airflow can only enter the ventilation duct through the second end 120 from bottom to top, and there is a large airflow resistance. However, the shielding assembly 700 according to the embodiment of the present disclosure is adopted, so that the outdoor vent 120 of the ventilation duct 100 may be disposed upward, and the connection portion 710 is provided with the vent 713. In this way, the cross-flow airflow is also made more accessible to the ventilation duct 100.
