Detailed ways

The embodiment provides an indoor unit of an air conditioner with a purifying function, and the purifying function of the indoor unit of the air conditioner can be turned on and off as needed. The indoor unit of the air conditioner is provided with a driving device and a purifying assembly, wherein the purifying assembly is driven by the driving device to move between the purging position at the air outlet of the indoor unit and the position at which the air inlet is removed, and the purifying assembly is not turned on when the purifying function is turned on. The air outlet is removed, and after the purifying function is turned on, the purifying assembly is driven by the driving device to move to the purifying position at the air outlet of the indoor unit to purify the airflow sent by the indoor unit.

As the purification component is in the purification process, its purification function will gradually decrease, so it needs to be replaced or cleaned and maintained. An optional reminder maintenance program is to replace it regularly, but the regular replacement does not take into account the actual use time of the purification component. . In the air conditioner indoor unit of the embodiment, the purifying function can be switched as needed, so the time at which the purifying assembly is actually in the purging position is not determined, so the scheme of regular replacement does not apply to the air conditioner with purifying function of the embodiment. Indoor unit. Moreover, since the purifying assembly can be moved and set, it is inconvenient for replacement and disassembly.

The air conditioner indoor unit having the air purifying function may preferably be a wall-mounted indoor unit. Since the wall-mounted indoor unit has a more compact structure, the space for arranging the purifying assembly is more narrow. This embodiment optimizes the structure of the wall-mounted indoor unit and utilizes more. The compact structure achieves the above purification function. 1 is a schematic structural view of an air conditioner indoor unit 100 having an air purifying function according to an embodiment of the present invention. Fig. 2 is a schematic view showing another angle of the air conditioner indoor unit 100 having the air purifying function shown in Fig. 1. The air conditioner indoor unit 100 with a purifying function of this embodiment may generally include a bobbin 110 for supporting the fan 180 and the heat exchanger 160, a casing 120 that is housed on the bobbin 110, and a casing 120 disposed in front of the casing 120. The front panel 130 is formed to form the front surface of the air conditioner indoor unit 100. Specifically, the top of the casing 120 is provided with an entrance grille, and the air inlet 101 is formed on the entrance grille to allow ambient air to enter the air conditioner indoor unit 100. The skeleton 110, the casing 120, and the front panel 130 may collectively constitute a casing of the air conditioner indoor unit 100. An air outlet 102 is opened at a lower portion of the casing for supplying air to the room.

The air conditioner indoor unit 100 further includes a purification assembly 150 and at least one driving device 140. The driving device 140 may be disposed in the casing, and the purifying assembly 150 is coupled to the driving device 140 and configured to be moved into or out of the purging position of the air outlet 102 of the shielding indoor unit by the driving of the driving device 140.

The purifying assembly 150 is configured in the purging mode to be driven by the driving device 140 to move into the purging position of the air outlet 102 (for example, the tuyere 102 can be completely shielded) to purify the airflow discharged from the indoor unit. When the purification assembly 150 is not cleaned, the drive unit can be driven out of the air outlet 102 to the standby position to expose the tuyere 102 so that the air flow does not directly flow out of the casing through the purification assembly 150. Further, by extending the stroke of the driving device 140, the cleaning assembly 150 can also be further removed from the standby position to the outside of the indoor unit 100 to the replacement position, facilitating the user to replace and clean the cleaning assembly 150.

Since the air conditioner indoor unit 100 of the present embodiment is provided with the movable cleaning assembly 150, the cleaning assembly 150 can be moved to the inner side of the air outlet 102 to shield the air outlet 102 when the air quality needs to be improved, so that the air outlet 102 is to be discharged. The airflow of the air conditioner indoor unit 100 is purified to improve the air quality of the indoor environment, and the purifying assembly 150 is located at the air outlet 102 when the air is purified, that is, the air outlet path of the fan 180, so that the wind resistance can be applied to the air conditioner. The influence of the air volume and the wind speed of the indoor unit 100 is minimized, and the indoor air can be purified while ensuring the cooling and heating efficiency of the air conditioner indoor unit 100.

In some embodiments of the invention, the drive device 140 can be configured to be controllable to move up and down along the inside of the front surface of the cabinet. The purifying assembly 150 can be coupled to the driving device 140 and configured to be moved up and down within the casing by the driving device 140. In particular, the purification assembly 150 can be controlled to move up to the inside of the air outlet 102 and completely shield the air outlet 102 to purify the airflow flowing into the air outlet 102 within the cabinet.

When purification is not required, the purification assembly 150 is moved down by the drive to a standby position (e.g., the outer or inner side of the casing below the air outlet 102).

3 is a schematic side cross-sectional view of the air conditioner indoor unit 100 having an air purifying function in a purified state, according to an embodiment of the present invention. Fig. 4 is a side cross-sectional view showing the air conditioner indoor unit 100 having the air purifying function shown in Fig. 3 in a standby state. When the purging is required, the purifying assembly 150 of the air conditioner indoor unit 100 can be moved to the position facing the air outlet 102 by the driving device 140, and the air outlet 102 can be completely covered on the inner side of the casing. Therefore, the airflow sent out by the air outlet 102 can be purified, that is, all the air that will flow out of the casing from the air outlet 102 needs to be purified by the purification component 150, so that the quality of the indoor ambient air can be gradually improved. Optimize until the user's needs are met.

When purification is not required, the purification assembly 150 can be moved from the inside of the air outlet 102 to the standby position (eg, the outside or inside of the air outlet 102 of the cabinet) under the driving of the driving device 140. That is, the purification assembly 150 can be moved to the lower side of the casing to expose the air outlet 102, thereby reducing the wind resistance at the air outlet 102, making the air conditioner more energy efficient and environmentally friendly.

When the cleaning assembly 150 needs to be replaced and cleaned, the cleaning assembly 150 can be further moved from the standby position to the outside of the indoor unit 100 by the driving device 140 to facilitate the user's operation.

The air conditioner indoor unit 100 further has a dust filter net disposed at the air inlet. When the airflow enters the casing, the dust, particles and the like are filtered through the filter dust net to prevent impurities such as dust and particles from flowing through the purification component 150. However, the use of the purification group is affected, and at the same time, the purification assembly 150 is prevented from accumulating dust after a long time of use and needs to be frequently cleaned or replaced.

Fig. 5 is a schematic structural view of a purifying assembly 150 and a driving device in a wall-mounted air conditioner indoor unit according to an embodiment of the present invention. Referring to FIG. 5, in some embodiments of the invention, the drive unit 140 can include a motor 141, a gear 142, and a curved rack 143. The motor 141 may be fixed to the lateral side end of the casing 120 and configured to controlably output driving forces in opposite directions. The gear 142 can be configured to be coaxially coupled to the output shaft of the motor 141 for rotation under the drive of the motor 141. The curved rack 143 can be configured to mesh with the gear 142 to move in the direction of its own extension with the drive of the gear 142. Further, the purification assembly 150 can be configured to be coupled to the curved rack 143 for movement with the curved rack 143.

In some embodiments of the present invention, the driving device 140 may preferably be two, and the two driving devices 140 are disposed opposite to each other in the lateral direction of the casing. Specifically, it may be located inside the left and right end caps forming the left and right side surfaces of the cabinet, respectively.

Further, the lateral ends of the purification assembly 150 can be respectively coupled to the curved racks 143 of the two driving devices 140, thereby making the movement of the purification assembly 150 at the air outlets 102 more stable.

In other embodiments of the invention, the casing 120 can have a plurality of support frames that can be configured to extend from below the air inlet 101 along an arcuate curve to the air outlet 102. The support frame and the skeleton 110 collectively define an interior space for the fan 180 and the heat exchanger 160. Two driving devices 140 may be disposed at the lower portions of the two support frames on the left and right sides of the casing 120, respectively. The two drive devices 140 are mirror-symmetrically disposed on the two support frames. At this time, the two motors 141 of the two driving devices 140 need to simultaneously output the driving forces in the opposite directions, so that the two curved gears 142 of the two driving devices 140 can be synchronously moved in the same direction.

In some embodiments of the present invention, each of the driving devices 140 may further include a limiting portion (not shown), and the limiting portion may be disposed on an outer side surface of the rack. Further, a limiting slot corresponding to the limiting portion may be disposed on the casing. For example, a limiting slot may be disposed at a position corresponding to the limiting portion of one or several supporting frames of the cover 120, and the limiting slot is configured to have a movement with the limiting portion to move with the rack. The direction of the path is consistent, so that the moving direction of the rack can be restricted by the cooperation relationship between the limiting portion and the limiting slot. Of course, those skilled in the art can also select other suitable mechanisms to restrict the degree of freedom of the rack, and details are not described herein again.

In some embodiments of the invention, the teeth of the curved rack 143 are located on their concave sides. The curved rack 143 has a plurality of connectors extending outwardly from a convex side surface thereof away from the gear 142 for opening a connection to the cleaning assembly 150. Further, a plurality of connectors are disposed to be spaced apart at an upper portion of the curved rack 143.

That is, the concave side of the curved rack 143 meshes with and rotates/moves around the gear 142. The curved rack 143 can be configured to have a relatively flat curvature similar to that of the air conditioner indoor unit front panel 130. Accordingly, the curved rack 143 can be configured to have an arc shape that is contoured with the curved rack 143, whereby the purifying assembly 150 can be more conformed when the rotating rack 150 is rotated/moved to the air outlet The front surface of the casing avoids interference with the installation space of the heat exchanger 160 or the fan 180, and makes the indoor unit of the air conditioner more beautiful.

In some embodiments of the present invention, a plurality of spaced apart connecting holes are respectively formed on the lateral end faces of the cleaning assembly 150, and the plurality of connecting holes respectively correspond to the through holes of the plurality of connecting members, and pass through the plurality of connecting pins. The connection is made such that the purification assembly 150 is attached to the curved rack 143.

In other embodiments of the present invention, the end faces of the cleaning assembly 150 may also extend outwardly from the plurality of connecting posts and cooperate with the through holes of the plurality of connecting members in a one-to-one correspondence. Since the purifying assembly 150 is spaced apart from the plurality of connecting points of the curved rack 143, the moving directions of both are substantially vertically upward and downward. Thereby, the cleaning assembly 150 can be firmly attached to the curved rack 143 by a simple laterally disposed connecting member, and it does not have problems such as turning over during the movement.

In some embodiments of the present invention, the purification assembly 150 is configured such that when the curved rack 143 is moved to a position where the teeth at the upper end thereof mesh with the gear 142, the purification assembly 150 is entirely removed from the outside of the indoor unit 100, the upper side thereof The edge is not higher than the lower edge of the air outlet 102 to allow the air outlet 102 to be fully opened. Correspondingly, when the curved rack 143 is moved to a position where the teeth at the lower end thereof mesh with the gear 142, the upper side edge of the purifying assembly 150 is not lower than the upper edge of the air outlet 102, and the lower side edge thereof is not higher than the air outlet. The lower edge of 102 is such that the air outlet 102 is completely shielded by the cleaning assembly 150.

Specifically, the length of the purification assembly 150 may be approximately 1/3 to 1/2 of the curved rack 143, and its mounting position is disposed on the upper half of the curved rack 143. Thereby, the upper end edges of the purifying assembly 150 and the curved rack 143 can be located in the same plane, and when the air outlet 102 is fully opened, the lower edge of the air outlet 102 can also fall into the plane. Thereby, the movement stroke required for the driving device is minimized, that is, the length of the curved rack 143 can be reduced as much as possible, the overall manufacturing cost is reduced, and the installation space is saved.

In normal use, the purifying assembly 150 is driven by the driving device 140 to move between the purging position of the air outlet that completely shields the indoor unit and the standby position that is separated from the air outlet. When the purifying function is not turned on, the purifying assembly 150 is located at the exiting air outlet. The standby position; after the purging function is turned on, the purifying assembly 150 is driven by the driving device 140 to move to the purging position of the air outlet that completely shields the indoor unit, and purifies the airflow entering the indoor unit.

When the cleaning assembly 150 needs to be replaced and cleaned, the stroke of the curved rack 143 can be maximized, and the purification assembly 150 can be removed from the outside of the indoor unit 100 for easy replacement. The spare position of the purification assembly 150 may be located below the air outlet 102, and the replacement position is located below the air outlet 102.

In some embodiments of the present invention, limit switches corresponding to the purging position, the standby position, and the replacement position, respectively, may be provided to indicate the position of the purifying assembly 150 to improve the motion accuracy of the driving device 140.

6 is a functional block diagram of an air conditioner indoor unit 100 having an air purifying function having a purifying assembly 150, a driving device 140, a detecting device 170, and a prompt according to an embodiment of the present invention. Device 190.

The purifying assembly 150 is driven by the driving device 140 to move into or out of the purging position of the shielding tuyere 102, wherein the driving device 140 is configured to controlly move the purifying assembly 150 to the purifying position after receiving the trigger signal of the air conditioner entering the purifying mode. The air outlet of the indoor unit 100 is purified by the purification unit 150. After obtaining the trigger signal of the air conditioner exiting the purification mode, the driving device 140 controls the driving purification assembly 150 to move out of the purification position to the standby position, so that the air outlet of the indoor unit 100 is directly sent out without being purified. When the driving device 140 is controlled to move the cleaning assembly 150 to the replacement position, the controlled driving purification assembly 150 is first removed from the cleaning position, and continues to move after passing through the standby position until the cleaning assembly 150 is completely removed from the outside of the air conditioner indoor unit 100. . The trigger signal for entering the purification mode includes any one or more of the following: an air pollution overrun signal reported by the air quality detecting device, a start operation signal from the user, and a timing start signal; and the trigger signal for exiting the clean mode includes any one of the following Or a plurality of: an air cleaning signal reported by the air quality detecting device, a shutdown operation signal from the user, and a timing exit signal.

The detecting device 170 is configured to detect the purging state of the purifying assembly 150, and the prompting device 190 may output prompt information prompting to replace or clean the purifying assembly 150 when the purifying state satisfies the preset prompting condition, and the prompting condition may include the purifying component 150. The usage time exceeds the preset time threshold. Accordingly, the detecting step of the detecting device 170 includes: accumulating the working time of the air outlet of the purifying unit 150 in the purifying position purifying indoor unit 100 and the standby time of removing the purifying position, respectively. The purification accumulation time of the purification component 150 and the standby accumulation time are obtained; and the usage time of the purification component 150 is calculated according to the purification accumulation time and the standby cumulative time.

For some of the purification assemblies 150, although the purification assembly 150 is located in the standby position, it is still subject to external contamination. Therefore, in this embodiment, not only the purification accumulation time but also the standby accumulation time is further considered. Due to the difference in the service life and characteristics of the different purification components 150, the detecting device 170 can calculate the usage time of the purification assembly 150 by determining the corresponding loss coefficient according to the type of the purification assembly 150, and the loss coefficient includes the purification loss coefficient and the standby loss, respectively. The coefficient is accumulated by using the product of the purification loss coefficient and the purification cumulative time and the product of the standby loss coefficient and the standby cumulative time to obtain the use time of the purification component 150.

The loss factor may be related to the arrangement manner of the indoor unit 100 and the arrangement position of the purification assembly 150, and may be set in advance. For example, in the standby state of the purification assembly 150, the above-mentioned standby loss coefficient may be set to 0; and the purification loss coefficient may be set. Is 1. For another example, when the cleaning assembly 150 is in the standby position, although no airflow is passed, but the external environment is affected, the above-mentioned standby loss coefficient may be set to 0.2; and the purification loss coefficient may be set to 1.

The above-mentioned purification loss coefficient and the standby loss coefficient can be obtained by performing a large number of tests on the indoor unit 100 and the purification unit 15 so that the estimated filtration time meets the specific loss of the purification unit 150, and the above specific values are only examples. Description.

The prompting device 190 can output the prompt information by using the prompt light set on the panel of the indoor unit 100 to output a corresponding prompt signal; or feeding back the prompt information to the remote control device of the air conditioner, so that the screen display of the remote control device corresponds to the prompt information. icon. In other optional embodiments, the prompting device 190 may also output prompt information by sending a prompt message or the like to the user terminal bound to the air conditioner, so that the user performs cleaning and maintenance according to the prompt information.

The control process of the air conditioner indoor unit 100 of the above embodiment will be further described below in conjunction with the control method of the air conditioner indoor unit with the purifying function of the present embodiment. The control method of the embodiment can be cleaned by the above described method. The function of the air conditioner indoor unit executes, promptly outputs prompt information prompting replacement or cleaning of the purifying assembly 150, thereby avoiding failure due to an increase in the use time of the purifying assembly 150. 7 is a schematic diagram of a control method of an indoor unit of an air conditioner with a purifying function according to an embodiment of the present invention. The control method can generally include:

Step S702, after receiving the trigger signal that the air conditioner enters the purification mode, the control driving device 140 moves the purification component 150 to the purification position to enter the purification mode. The trigger signal entering the purification mode may include: an air pollution overrun signal reported by the air quality detecting device, a start operation signal from the user, and a timing start signal.

For the air pollution over-limit signal, the air quality detecting device detects that the air pollution of the working environment of the air conditioner indoor unit 100 reaches the set over-limit threshold (for example, each parameter exceeds the limit or the pollution level exceeds the limit, etc.), and the air conditioner can be triggered. Enter the purification mode.

For the start operation signal, the user can manually trigger the air conditioner to enter the purification mode through the remote controller or other air conditioner human-computer interaction interface.

For the timing start signal, the air conditioner can be cleaned regularly according to the running time, for example, the accumulated work for 8 hours, and the purification is started for 1 hour.

The trigger signal of the above air conditioner entering the purifying mode can be set according to the user's requirements for air purification. The air outlet of the indoor unit 100 is purified by the purification unit 150.

Step S704, detecting a purification state of the purification component 150; the purification state may include a working time of the purification component 150. Since the purification assembly 150 may also be contaminated by the external environment in the standby position, the working time of the above-described purification assembly 150 also needs to consider the standby time of the standby position. For example, one detection method of step S704 is to accumulate the working time of the air outlet of the purifying unit 150 in the purifying position purifying indoor unit 100 and the standby time of removing the purifying position, respectively, to obtain the purifying cumulative time and the standby accumulating time of the purifying unit 150. And calculating the usage time of the purification component 150 according to the purification accumulation time and the standby cumulative time.

In this embodiment, not only the purification accumulation time but also the standby accumulation time is further considered. Due to the difference in the service life and characteristics of the different purification components 150, the usage time of the purification component 150 can be calculated as follows: the corresponding loss coefficient is determined according to the type of the purification component 150, and the loss coefficient includes the purification loss coefficient and the standby loss coefficient, respectively; The product of the purification loss coefficient and the purification cumulative time and the product of the standby loss coefficient and the standby cumulative time are accumulated to obtain the use time of the purification component 150.

The above-mentioned purification loss coefficient and the standby loss coefficient can be obtained by performing a large number of tests on the indoor unit 100 and the purification unit 15 so that the estimated filtration time meets the specific loss of the purification unit 150. The above specific values are merely examples. Description.

In step S706, when the purifying state meets the preset prompting condition, the prompt information for prompting replacement or cleaning of the purifying component is output, and the prompting condition includes: the usage time of the purifying component 150 exceeds a preset time threshold. If the usage time of the purification component 150 is exceeded, the prompt information can be output in time. The prompt information may be output by using a prompt light set on the panel of the indoor unit 100 to output a corresponding prompt signal; or feeding back the prompt information to the remote control device of the air conditioner so that the screen of the remote control device displays an icon corresponding to the prompt information. In other optional embodiments, the prompt information may also be output by sending a prompt message to the user terminal bound to the air conditioner, so that the user performs cleaning and maintenance according to the prompt information.

Step S708, the control driving device 140 drives the purification component 150 to move out of the purification position to a replacement position located outside the air conditioner indoor unit 100. Since the replacement position is located outside the air conditioner indoor unit 100, the user's operation is greatly facilitated.

In addition, during the purification process, the purification component 150 can be taken out of operation as needed, for example, obtaining a trigger signal for the air conditioner to exit the purification mode, and controlling the driving device 140 to drive the purification component 150 to move out of the purification position to the standby position, so that the indoor unit 100 The wind is sent directly. The trigger condition for exiting the purification includes any one or more of the following: an air cleaning signal reported by the air quality detecting device, a shutdown operation signal from the user, and a timing exit signal. For example, the air pollution parameter is reduced to a preset purge closing threshold signal; the purge time is over time signal; the air pollution parameter continues to have no improved signal. For example, after purification, the working environment of the air conditioner indoor unit 100 has been improved, and then the purification can be exited. In addition, if the continuous purification time exceeds a certain period of time, you can also exit the purification. In the purification process, if the air pollution parameter continues to be no improvement or deteriorates, it indicates that the purification component 150 does not function, and the purification can also be withdrawn at this time.

The control driving device 140 drives the purifying assembly 150 to move out of the purging position to reach the replacement position outside the indoor unit of the air conditioner. The driving device 140 may be first controlled to drive the purifying assembly 150 to be removed from the purging position, and then continue to move after passing the standby position until the purifying assembly 150 is completely removed from the outside of the air conditioner indoor unit 100.

The control method of the air conditioner indoor unit with the purifying function according to the cleaning state of the purifying unit 150 controls the driving device 140 to drive the purifying unit 150 to move out of the purifying position to the replacement position outside the air conditioner indoor unit 100, and output in time. The prompt information is convenient for the user to replace or clean, thereby avoiding failure with the increase of the use time of the purification component 150, eliminating secondary pollution and improving the user experience.
