[0002] In most existing wall-mounted self-cleaning air conditioners, the dust removal components of the air inlet are located at the top of the unit.

[0003] However, placing the dust removal component at the top of the unit increases the overall height, which limits installation options.

Detailed Implementation

[0059] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the invention as detailed in the appended claims.

[0060] Currently, the dust removal components of existing air conditioner indoor units are located at the top of the unit, which has limitations in installation, affects the heat exchange efficiency of the unit, and makes it easy for dust to re-contaminate other parts of the unit. This invention proposes a dust removal control method for a wall-mounted air conditioner indoor unit, an air conditioner, and its filter. By placing the cleaning mechanism and dust collection mechanism in the original space on the side of the unit, it is convenient to install the cleaning mechanism and dust collection mechanism, and the cleaning mechanism and dust collection mechanism will not affect the air intake. At the same time, by setting an auxiliary dust reduction device, the falling speed of dust after cleaning can be accelerated, preventing dust from falling on other parts of the unit and improving the dust removal effect.

[0061] The following is in conjunction with the appendix Figure 1 - Appendix Figure 8 The technical solution of this embodiment is described in detail. Unless otherwise specified, the following implementation methods and embodiments can be combined with each other.

[0062] Example

[0063] like Figures 1-8 As shown, the first aspect of this invention provides a wall-mounted air conditioner indoor unit, comprising:

[0064] The body 1 has an air inlet 11 formed on its top side;

[0065] Heat exchanger 2 is located inside body 1. A top space 3 is defined between the upper side of heat exchanger 2 and the upper side of body 1. A front space 4 and a rear space 5 are defined between the front and rear sides of heat exchanger 2 and the front and rear sides of body 1, respectively.

[0066] The top track 61 and the side track 71 are connected to form a filter track for the filter screen 8 to move. The top track 61 is located in the top space 3, and the side track 71 is located in the front space 4 or the rear space 5.

[0067] The filter screen 8 is movably installed in the filter screen track. When the filter screen 8 moves, it has a filtering position that blocks the air inlet 11 and a position that avoids the air inlet 11.

[0068] The cleaning mechanism 9 and the dust collection mechanism 10 are used to clean the surface of the filter screen 8 when the filter screen 8 moves, and the dust collection mechanism 10 is used to collect the dust that falls off when the cleaning mechanism 9 cleans the filter screen 8.

[0069] The space where the side track 71 is located also forms a dust falling channel 100. The cleaning mechanism 9 and the dust collection mechanism 10 are set on the upper and lower sides of the dust falling channel 100. When the cleaning mechanism 9 cleans the filter screen 8, the dust that falls off can fall into the dust collection mechanism 10 through the dust falling channel 100.

[0070] The indoor unit also includes an auxiliary dust-reducing device 200 to accelerate the falling speed of dust in the dust falling channel 100.

[0071] In this embodiment of the invention, by setting the cleaning mechanism 9 and the dust collection mechanism 10 in the original space on the side of the machine body, it is convenient to install the cleaning mechanism 9 and the dust collection mechanism 10. On the other hand, the cleaning mechanism 9 and the dust collection mechanism 10 will not affect the air intake of the air inlet 11 of the machine body 1. At the same time, by setting the auxiliary dust removal device 200, the falling speed of dust after being cleaned can be accelerated, preventing dust from falling on other parts inside the machine body 1 and improving the dust removal effect.

[0072] It should be noted that when the cleaning mechanism 9 cleans the moving filter screen 8, the cleaned dust will fall from top to bottom into the dust collection mechanism 10. Since the dust is relatively light, it will re-contaminate the filter screen 8 and other parts inside the machine body 1 during the falling process. Therefore, the auxiliary dust suppression device 200 is set to speed up the falling speed of the dust in order to avoid the problem of secondary pollution.

[0073] It should also be noted that, such as Figure 2 and Figure 3 Preferably, the cleaning mechanism is a dust removal brush rotatably installed inside the body 1. The dust removal brush has a dust removal position and a self-cleaning position when it rotates. When it is necessary to clean the filter screen 8, the dust removal brush can be controlled to rotate to the dust removal position opposite to the filter screen 8 so as to clean the filter screen 8 with the bristles. When it is not necessary to clean the filter screen 8, the dust removal brush can be controlled to rotate to the self-cleaning position to achieve the self-cleaning effect of the dust removal brush.

[0074] Specifically, when the dust removal brush rotates to the self-cleaning position, it can contact the cleaning teeth on the dust removal cover plate (the dust removal cover plate is used to cooperate with the dust removal bracket, and the two cooperate to define the dust falling channel, and the dust removal bracket has the aforementioned side track) to achieve the self-cleaning effect of the dust removal brush. At the same time, the dust that falls off the dust removal brush during self-cleaning can also be collected by the dust collection mechanism through the dust falling channel.

[0075] In the above technical solution, the auxiliary dust suppression device can perform cooling and / or humidification and / or atomization treatment on the dust falling channel.

[0076] Specifically, by cooling the dust falling channel, the temperature of the airflow in the dust falling channel is reduced. Due to the principle of cold air sinking, the falling speed of dust in the dust falling channel can be increased.

[0077] More specifically, by atomizing and / or humidifying the dust falling channel, the humidity and weight of the dust in the channel can be increased, thereby increasing the falling speed of the dust in the channel.

[0078] In some implementations, such as Figures 2-6 As shown, the dust collection mechanism 10 includes a dust collection box with an opening at the top, the opening communicating with the bottom of the dust falling channel 100;

[0079] The dust collection box is used to collect condensate produced by the indoor unit and / or condensate produced by the outdoor unit that is connected to the refrigerant of the indoor unit;

[0080] The auxiliary dust suppression device 200 includes liquid handling equipment and / or condensate pipes;

[0081] The liquid handling equipment is located inside the dust collection box and is used to humidify and / or atomize the condensate in the dust collection box before applying it to the dust falling channel 100 to accelerate the falling speed of dust in the dust channel.

[0082] The condensate drain pipe is attached to the surface of the dust collection box and is used to circulate condensate produced by the indoor unit and / or condensate produced by the outdoor unit connected to the indoor unit's refrigerant, in order to accelerate the falling speed of dust in the dust channel.

[0083] Preferably, the liquid handling device includes a water mist nozzle located at the bottom of the dust collection box, which generates water mist to humidify the air in the dust falling channel. When cleaning the filter screen begins, the water mist nozzle simultaneously starts spraying water mist to humidify the air, causing the brushed-off dust to quickly fall into the dust collection box in the dust falling channel 100, preventing re-contamination of the filter screen and other parts.

[0084] Preferably, the condensate pipe is attached to the outer wall of the dust collection box to cool the dust collection box, thereby cooling the airflow in the dust falling channel and increasing the dust falling speed in the dust falling channel.

[0085] In a further preferred embodiment, when the auxiliary dust collection device includes both a liquid handling device and a condensate pipe, the condensate pipe attached to the outer wall and / or inner wall of the dust collection box can also condense the water in the dust collection box. This allows the liquid handling device to atomize and / or humidify the dust falling channel while simultaneously cooling the dust falling channel with the atomized water vapor at a lower temperature, thereby further increasing the dust falling speed in the dust falling channel.

[0086] In some implementations, such as Figures 4-6 As shown, a water collection trough is formed inside the dust collection box. The inner bottom wall of the water collection trough is designed to be inclined, and the inclined inner bottom wall has a lowest position and a highest position.

[0087] The dust collection box is also provided with a water inlet 101 and a drain outlet 102. The water inlet 101 is located on the side of the dust collection box and is positioned close to the highest position relative to the lowest and highest positions. The drain outlet 102 is located at the bottom of the dust collection box and is positioned close to the lowest position relative to the lowest and highest positions.

[0088] By setting the drain outlet 102, water that has not been used for a long time in the water collection box can be drained to avoid odor. At the same time, by setting the drain outlet 102 at the lowest position, the water collection box can be drained more thoroughly, avoiding water stains.

[0089] In some implementations, such as Figures 4-6 As shown, an overflow port 103 is also provided on the side wall of the dust collection box. The overflow port 103 is used to drain excess water from the dust collection box when the water level in the dust collection box is higher than the first preset water level; and / or

[0090] The dust collection box is also equipped with a water level detection device 104. The indoor unit can issue an alarm message when the water level detection device 104 detects that the water level in the dust collection box is higher than the second preset water level. The first preset water level is higher than the second preset water level.

[0091] The alarm information may include text information and / or voice information and / or light information, that is, the user can be reminded through a variety of different alarm information or a combination of a variety of different alarm information. In this embodiment of the invention, the specific presentation method of the alarm information is not limited.

[0092] By setting an overflow port 103, excess water can be automatically discharged when the water level in the collection box is too high. Preferably, the overflow port 103 and the drain port 102 can be connected to the same drain pipe. Furthermore, to prevent the dust collection box drain port or drain pipe from becoming blocked, causing the dust collection box to accumulate water for a long time and emit an odor, a water level detector can be installed. Figure 6 As shown. When the drain outlet is blocked, the water level in the dust collection box will slowly rise. When the water level in the dust collection box triggers the water level detector, the air conditioner will sound an alarm, reminding the user to clean the drain outlet or drain pipe in time. At the same time, there is an overflow port on the left side of the dust collection box, which can be connected to a drain pipe. When the water exceeds the overflow port, it will automatically flow out from the overflow port and out of the indoor unit with the drain pipe.

[0093] In this embodiment, by setting an overflow port and a water level sensor on the dust collection box, the problem of water overflowing from the dust collection box can be effectively avoided.

[0094] In some embodiments not shown, the dust collection mechanism 10 includes a dust collection box with an opening at the top;

[0095] The auxiliary dust collection device 200 includes a dust collection device located inside the dust collection box. The dust collection device can suck the dust in the dust falling channel 100 into the dust collection box during operation, so as to accelerate the falling speed of the dust in the dust falling channel 100.

[0096] The dust suction port of the dust collection device is also equipped with a detachable filter structure to filter the sucked-in dust.

[0097] The vacuum cleaner quickly sucks up dust into the dust collection box, while the filter structure (such as filter paper or filter sponge) filters out the dust, preventing it from entering the vacuum cleaner. The filter layer is detachably mounted on the upper side of the vacuum cleaner; when a certain amount of dust accumulates and the filtration effect deteriorates, the user can remove and replace it.

[0098] It is worth noting that, such as Figure 1 As shown, in some embodiments, the dust collection box described above can be pulled out from the side of the machine body and installed inside the machine body, thereby facilitating the cleaning of the dust collection box.

[0099] To better understand the interaction and effectiveness of the dust collection box and filter screen in dust removal in this application, the dust removal steps using a water mist nozzle installed inside the dust collection box as an example will be explained in detail below:

[0100] Specifically, such as Figure 7 As shown, when running the filter cleaning function, the system first obtains the current water level in the dustbin and compares it with the set water level.

[0101] If the current water level in the dust collection box exceeds the set water level, the filter will begin cleaning. The filter moves from the top track to the side track, and simultaneously, the water mist nozzles inside the dust collection box begin spraying to humidify the air in the dust falling channel 100. After cleaning, the water mist nozzles stop spraying, the filter returns to the top track, the dust collection box drain opens, and wastewater is discharged from the dust collection box into the indoor unit. To facilitate wastewater discharge from the dust collection box, the bottom of the dust collection box should be designed with the drain side at a lower position.

[0102] If the current water level in the dust collection box is less than the set water level, the filter cleaning will not begin, the filter will not move, and the water mist nozzle will not spray air. At this time, the user will be reminded to manually add water or activate the defrost mode to generate condensate. {It is worth noting that generating condensate by running the defrost mode on the air conditioner is a well-known method, and the specific control logic of the defrost mode will not be described in this embodiment.} When the water level in the dust collection box is detected to reach the set water level again, the filter cleaning will automatically begin and subsequent procedures will be performed.

[0103] In some implementations, such as Figure 2 and Figure 3 As shown, the cleaning mechanism 9 is located at the top of the side track 71, and the dust collection mechanism 10 is located at the bottom of the side track 71.

[0104] The length of the side track 71 located between the cleaning mechanism 9 and the dust collection mechanism 10 is adapted to the length of the filter screen 8.

[0105] In this embodiment of the invention, the cleaning mechanism is located near the top of the body 1. When the filter screen slides from the top track into the side track, the cleaning mechanism 9 can promptly clean the filter screen 8. Compared to a top-mounted roller track, where the filter screen needs to slide through an empty track for a short distance before contacting the cleaning mechanism, the track design must accommodate this empty travel. Therefore, the former method has a higher track utilization rate.

[0106] In some implementations, such as Figure 2 and Figure 3 As shown, an air inlet grille 6 is provided in the top space 3, and the air inlet grille 6 forms a top track 61 for the filter screen 8 to move along the front and rear direction of the body 1.

[0107] A dust removal bracket 7 is provided in the front space 4 or the rear space 5. The dust removal bracket 7 forms a side track 71 for the filter screen 8 to move along the vertical direction of the body 1.

[0108] The side track 71 is formed on the side of the dust removal bracket 7 away from the heat exchanger 2, and the cleaning mechanism 9 is set on the side of the dust removal bracket 7 away from the heat exchanger 2.

[0109] In this embodiment of the invention, by setting the cleaning mechanism 9 on the side of the dust removal bracket 7 away from the heat exchanger 2, the dust cleaned by the cleaning mechanism 9 can be prevented from contacting the heat exchanger 2, thus ensuring the heat exchange effect of the heat exchanger 2.

[0110] In some implementations, such as Figure 2 and Figure 3 As shown, the indoor unit also includes a dust removal cover plate that is mated and cooperates with the side of the dust removal bracket 7 away from the heat exchanger. The dust removal cover plate and the dust removal bracket 7 are mated and cooperated to form a dust removal component with a dust falling channel 100 inside.

[0111] in

[0112] The dust removal component is detachably installed in the rear space 5 inside the body 1. The sides and / or bottom of the body are provided with dust removal component mounting and dismounting ports adapted to the shape of the dust removal component, so as to remove and install the dust removal component through the mounting and dismounting ports; and / or

[0113] The dust collection box is detachably installed in the rear space 5 inside the body. The side and / or bottom of the body are also provided with a dust collection box removal port adapted to the shape of the dust collection box, so as to remove and install the dust collection box through the dust collection box removal port.

[0114] like Figure 1 As shown, preferably, the side of the machine body is provided with a dust removal component installation port and / or a dust collection box installation port to facilitate the installation of the dust removal component and / or the dust collection box.

[0115] In some implementations, such as Figure 2 and Figure 3 As shown, the width of the front space 4 in the front-rear direction of the body 1 is smaller than the width of the rear space 5 in the front-rear direction of the body 1, and the side track 71 is set in the rear space 5 formed between the rear side of the heat exchanger 2 and the rear side of the body 1.

[0116] The side track 71 is constructed as a curved track with a notch facing the rear of the body 1, and the projection of the side track 71 in the vertical direction of the body 1 does not coincide with the projection of the air inlet 1 in the vertical direction of the body 1.

[0117] Preferably, in this embodiment of the invention, the dust collector bracket 7 and the dust collection box are located on the rear side of the air conditioner. Compared to placing the dust collector bracket 7 and the dust collection box on the front side of the air conditioner, the larger space at the rear of the air conditioner allows for the placement of the dust collector bracket 7 and the dust collection box on the rear side, freeing up space at the front of the heat exchanger 2. This facilitates air circulation, helps to enhance the heat exchange efficiency of the heat exchanger 2, and improves the overall performance of the unit. Furthermore, utilizing the rear space of the air conditioner allows for a staggered installation between the dust collector bracket 7 and the air inlet of the air conditioner. This avoids direct cold air blowing onto the dust collector bracket 7 and the dust collection box without affecting the heat exchange capacity of the heat exchanger, thus solving the problem of condensation on the surface of the dust collector bracket 7 and the dust collection box. The dust collection box can conveniently collect the condensate produced by the indoor unit's heat exchanger.

[0118] Meanwhile, by placing the dust removal component on the rear side of the air conditioner, users or maintenance personnel can easily remove the dust removal component from the side or bottom of the air conditioner for cleaning.

[0119] A second aspect of the present invention also provides an air conditioner, which includes an outdoor unit and a wall-mounted air conditioner indoor unit provided in the first aspect of the present invention.

[0120] like Figure 7 and Figure 8 As shown, a third aspect of the present invention also provides a method for controlling dust removal from an air conditioner filter, which is applied to the wall-mounted air conditioner room provided in the first aspect of the invention or the air conditioner provided in the second aspect of the invention. The air conditioner has a dust removal mode for removing dust from the filter, wherein the dust removal control method includes:

[0121] Obtain the cumulative dust amount s1 and s2 of the filter screen within two equal time intervals, and compare s1 and s2;

[0122] If s1 < s2, then shorten the operating frequency of the dust removal mode;

[0123] If s1≥s2, then the operating frequency of the dust removal mode will be extended.

[0124] Specifically, dust control methods also include:

[0125] In dust removal mode, the water volume in the dust collection box is measured;

[0126] If the water storage capacity in the dust collection box is greater than the preset water storage capacity, the liquid handling equipment will be controlled to atomize the water in the dust collection box.

[0127] If the water level in the dust collection box is less than or equal to the preset water level, a water filling alarm will be output and / or the air conditioner will be controlled to activate the defrosting mode to generate condensate.

[0128] The following is combined with Figure 7 and Figure 8 The defrosting mode of the air conditioner in this embodiment of the invention will be described in detail below:

[0129] like Figure 8 As shown: The detection device collects the cumulative dust volume of the filter screen S1 and S2 within two identical time intervals (the time interval can be set by the user, such as 1 week or 1 month). The device then compares the cumulative dust volume S1 and S2 between the two intervals. If S1 < S2, it indicates that the indoor air quality is gradually deteriorating, and the operating time interval is automatically halved (the adjusted interval can also be set by the user). This increases the operating frequency of the dust removal components, ensuring the filter screen is not clogged, allowing for smooth airflow, increasing the heat exchanger's efficiency, and making the air conditioner more energy-efficient (when the filter screen is clogged, airflow is obstructed, reducing the heat exchanger's efficiency; to achieve the same perceived temperature, the operating time will be longer and consume more electricity). This also makes the air conditioner blow healthier air. If S1 ≥ S2, it indicates that the indoor air quality is gradually improving, and the operating time interval is automatically doubled (the adjusted interval can also be set by the user). In this case, the operating frequency of the dust removal components is slowed down, reducing dust removal energy consumption and achieving energy savings for the air conditioner.

[0130] like Figure 7 As shown, when the filter cleaning function is activated, the system first obtains the current water level in the dustbin and compares it with the set water level.

[0131] If the current water level in the dust collection box exceeds the set water level, the filter will begin cleaning. The filter moves from the top track to the side track, and simultaneously, the water mist nozzles inside the dust collection box begin spraying to humidify the air in the dust falling channel 100. After cleaning, the water mist nozzles stop spraying, the filter returns to the top track, the dust collection box drain opens, and wastewater is discharged from the dust collection box into the indoor unit. To facilitate wastewater discharge from the dust collection box, the bottom of the dust collection box should be designed with the drain side at a lower position.

[0132] If the current water level in the dust collection box is less than the set water level, the filter cleaning will not begin, the filter will not move, and the water mist nozzle will not spray air. At this time, the user will be reminded to manually add water or activate the defrost mode to generate condensate. {It is worth noting that generating condensate by running the defrost mode on the air conditioner is a well-known method, and the specific control logic of the defrost mode will not be described in this embodiment.} When the water level in the dust collection box is detected to reach the set water level again, the filter cleaning will automatically begin and subsequent procedures will be performed.
