Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to a control method and system for an anti-shielding bracket of an indoor unit of an air conditioner, and an indoor unit of the air conditioner. Background Art

[0002] The indoor unit of the air conditioner currently used is generally set at a certain wall position of the house wall, and is generally biased towards the corner. There are generally windows in the room, and curtains are inevitably set at the windows. When the curtain is close to the indoor unit of the air conditioner, when the air conditioner is in use, the curtain is easily adsorbed at the air inlet position, thereby blocking the air inlet, and the indoor unit of the air conditioner cannot take in air, which makes it difficult to use the air conditioner or even damages the indoor unit of the air conditioner due to the inability to take in air. At present, there are some technologies for directly setting a bracket at the air inlet of the air conditioner to block most of the substances that may be adsorbed at the air inlet position. However, in this case, when there is no object blocking the air inlet, the bracket still exists at the air inlet position of the indoor unit of the air conditioner, which will cause the bracket at the air inlet position to occupy space, resulting in the entire indoor unit occupying a large space. At the same time, the bracket will also affect the air intake as one of the causes of wind resistance at the air inlet. Summary of the invention

[0003] An object of the first aspect of the present invention is to provide a control method for an anti-shielding bracket of an indoor unit of an air conditioner to solve the problem in the prior art that it is impossible to selectively prevent the curtain from blocking the air inlet according to the position of the curtain.

[0017] Optionally, when the air inlet area overlaps with the estimated space area, the step of controlling the bracket to move to the target position includes:

[0018] identifying the curtain position when the air intake area overlaps with the estimated space area;

[0019] Determining whether the curtain occupies the entire estimated space area according to the position of the curtain;

[0020] When the curtain occupies the entire estimated space area, the bracket is controlled to move to the target position.

[0021] Optionally, after the step of judging whether the curtain occupies the entire estimated space area according to the curtain position, the step further includes:

[0022] When the curtain does not occupy the entire estimated space area, obtaining whether the edge of the curtain is located in the air inlet area;

[0023] When it is determined that the edge of the curtain is located within the air inlet area, the bracket is controlled to move to the target position.

[0024] Optionally, when it is determined that the curtain does not occupy the entire estimated space area, the step of obtaining whether the edge of the curtain is located in the air inlet area includes:

[0025] When the edge of the curtain is located in the air inlet area, obtaining the air volume of the air inlet;

[0026] Whether it is necessary to control the bracket to move to the target position is determined according to the wind volume and a preset wind volume threshold.

[0027] Optionally, the step of judging whether it is necessary to control the bracket to move to the target position according to the wind volume and a preset wind volume threshold comprises:

[0028] Subtracting a preset air volume threshold from the air volume to obtain an air volume difference;

[0029] comparing the air volume difference with a difference threshold;

[0030] When the difference is greater than the difference threshold, the support is controlled to move to the target position.

The position and direction of the air inlet of the indoor unit of the air conditioner obtained by the air inlet detection device and the light sensor and the window position obtained by the light sensor are used to determine whether the air inlet area and the estimated area overlap. When the air inlet area and the estimated area overlap, the bracket is controlled to move to the target position. The target position is located in the air inlet area and is arranged in front of the air inlet, thereby blocking curtains or other materials outside, thereby preventing the curtains from blocking the air inlet of the air conditioner, thereby avoiding affecting the use of the air conditioner.

[0042] After obtaining the air inlet area and the estimated space area position, this solution also needs to further judge whether the curtains occupy the entire space area, and then more accurately confirm whether the curtains will block the air inlet. According to the confirmation result, the bracket is controlled to make the control of the bracket more precise, further avoiding some unnecessary bracket movements and reducing energy consumption.

[0043] The control method of the anti-shielding bracket of the indoor unit of the air conditioner in this scheme combines the judgment and comparison of whether the air inlet area overlaps with the estimated space area, whether the curtain occupies the entire estimated space area, whether the edge of the curtain is located in the air inlet area, and the amount of air at the air inlet, so as to accurately control the movement of the bracket, avoid the bracket being always at the air inlet to affect the appearance of the air conditioner and the air intake of the air inlet, and also improve the accuracy as much as possible, so that most of the curtains that may block the air inlet are blocked by the bracket, ensuring the normal use of the air conditioner.

[0057] Figure 1 is a schematic structural diagram of an air conditioner opening bracket when it is located at a target position according to a specific embodiment of the present invention. Figure 2 A schematic structural diagram of an air conditioner closing bracket in a state of returning to an original position according to a specific embodiment of the present invention. Figure 3Schematic diagram of an air conditioner indoor unit according to a specific embodiment of the present invention. As a specific embodiment of the present invention, this embodiment provides a control method for an anti-shielding bracket of an air conditioner indoor unit. The air conditioner indoor unit 100 of this embodiment may include a body 10, an air inlet detection device 11 arranged at the body 10, a light sensor 12 and a bracket 20. Among them, the air inlet detection device 11 may be a magnetic field sensor. The magnetic field sensor and the light sensor 12 are arranged inside the air conditioner indoor unit 100 (not shown in the figure). The positional relationship and angle relationship between the magnetic field sensor and the air conditioner indoor unit 100 are certain. The magnetic field sensor is used to obtain the position and air inlet direction of the air conditioner air inlet according to the data monitored by the magnetic field sensor. The light sensor is used to detect the position of the window of the space where the air conditioner is located. The bracket 20 is rotatably connected to the body 10 to block the target object from approaching the air inlet when the bracket 20 rotates to the target position.

[0058] Specifically, the magnetic field sensor of this embodiment can be an instrument similar to a compass, and when the air conditioner is installed, the magnetic field sensor is located in a horizontal position, so that the direction of the magnetic field can be well indicated. The position of the magnetic field sensor relative to the air inlet is determined, and when the magnetic field sensor obtains the orientation of the air conditioner, the position and direction of the air inlet will also be confirmed accordingly.

[0059] Specifically, the bracket 20 of this embodiment may include a connecting rod 21 rotatably connected to two opposite sides of the air conditioner indoor unit 100 and a crossbar 22 connecting the two connecting rods 21. The rotating connecting rod 21 has a rotating shaft (not shown), and the rotating shaft is controlled by a motor (not shown) to drive the connecting rod 21 to rotate. The bracket 20 can be rotated to a shell close to the body 10 (such as Figure 2 As shown in FIG. 1 , the cross bar 22 is embedded in the housing of the main body 10, and the outer surface forms a continuous plane. The cross bar 22 is similar to the decorative plate of the main body 10. When the bracket 20 is rotated to the target position (as shown in FIG. Figure 1 As shown in the figure, the bracket 20 is located in front of the air inlet 30, thereby preventing some of the target objects from approaching the air inlet, thereby avoiding blocking the air inlet. Specifically, the vertical distance between the cross bar 22 of this embodiment and the plane where the air inlet is located is approximately 1 to 1 / 4 of the distance between the edge of the air inlet area and the air inlet. The positional relationship and distance relationship between the cross bar 22 and the air inlet can be designed according to actual needs. In addition, the size and shape of the cross bar are not limited to the shapes shown in the drawings, and it can be a plate-shaped, round lamp, or even have a through hole and other structures therein.

[0060] Figure 4 1 is a schematic flow chart of a control method of an anti-shielding bracket of an air conditioner indoor unit according to a specific embodiment of the present invention. Specifically, as a specific embodiment of the present invention, the control method of this embodiment may include:

[0061] Step S100, obtaining the position and air inlet direction of the air inlet of the air conditioner, and obtaining the air inlet area according to the position and air inlet direction of the air inlet;

[0062] Step S200, obtaining the window position, and obtaining an estimated space area occupied by installing curtains at the window position according to the window position;

[0063] Step S300, determine whether the air intake area overlaps with the estimated space area; if so, execute step S400, if not, end the process.

[0064] Step S400, when the air inlet area overlaps with the estimated space area, controlling the bracket to move to a target position, wherein the target position is located at the air inlet area.

[0065] Specifically, generally speaking, in step S100, after the position and air inlet direction of the air inlet of the air conditioner are confirmed, its air inlet area 40 can be roughly known. Generally speaking, the wind speed of the air outlet of the indoor unit of the air conditioner also has a great influence on the area of ​​the air inlet. When the wind speed is high, the air inlet area is large, and when the wind speed is low, the air inlet area 40 will be correspondingly small. The size and shape of the area can be estimated based on the model parameters of the air conditioner.

[0066] In step S200, the light sensor can determine the position of the brighter side, and then determine the position of the window. Of course, this also needs to be done when the outdoor light is good. After the window position is determined, the space for installing curtains on the window can also be roughly estimated. Generally speaking, the installation space of the curtain can be estimated to basically occupy the position of the entire wall and be about 10-30 cm away from the wall.

[0067] In step 300, when the air inlet area and the estimated space area are obtained, it can be determined whether the air inlet area overlaps with the estimated space area. Generally speaking, when there is a partial overlap, it means that after the curtains are installed, the curtains are located in the air inlet area. When the air conditioner is in use, the curtains are easily adsorbed at the air inlet due to the wind pressure in the air inlet area, thereby affecting the normal use of the air conditioner. Therefore, in this embodiment, when the air inlet area overlaps with the estimated area, the bracket is controlled to move to the target position, and the target position is located in the air inlet area and is set in front of the air inlet, so that the curtains or other materials are blocked outside, thereby preventing the curtains from blocking the air inlet of the air conditioner, thereby avoiding affecting the use of the air conditioner.

[0068] Figure 5 A schematic flowchart of the steps of obtaining the position and air inlet direction of the air inlet of an air conditioner according to a specific embodiment of the present invention; as a specific embodiment of the present invention, step S100 of this embodiment, the step of obtaining the position and air inlet direction of the air inlet of the air conditioner may include:

[0069] Step S101, obtaining the magnetic pole direction using a magnetic field sensor;

[0070] Step S102, obtaining the air inlet direction according to the magnetic pole direction;

[0071] Step S103, obtaining the position of the air inlet according to the positional relationship between the magnetic field sensor and the air inlet.

[0072] Specifically, in this embodiment, the magnetic pole direction can be obtained by the magnetic field sensor, and the positional relationship between the magnetic field sensor and the air inlet is constant, and the relative position between the air inlet direction and the air inlet is also constant, so the air inlet direction can be obtained from the magnetic pole direction. The positional relationship between the magnetic field sensor and the air inlet is constant, so knowing the air inlet direction can also know the position of the air inlet.

[0073] Figure 6 A schematic flow chart of the steps of obtaining the window position according to a specific embodiment of the present invention; as a specific embodiment of the present invention, in step S200 of this embodiment, the step of obtaining the window position includes:

[0074] Step S201, using a light sensor to obtain a room light value;

[0075] Step S202: The position where the light value is greater than the preset light threshold is the window position.

[0076] Generally speaking, during the day, the light value at the window location will be higher than a certain value, while the light value at other walls or doors will be lower. The light on the top is not taken into account. Therefore, after the air conditioner is started, the light sensor can be used to monitor the light value in the room. When the light value is greater than the preset light threshold, the position can be identified as the window position, and the window position is the location where the curtain is installed.

[0077] Figure 7 A schematic flowchart of the steps of controlling the bracket to move to the target position when the air intake area overlaps with the estimated space area according to a specific embodiment of the present invention; as a specific embodiment of the present invention, step S400 of this embodiment, when the air intake area overlaps with the estimated space area, the step of controlling the bracket to move to the target position also includes:

[0078] Step S401, identifying the curtain position when the air intake area overlaps with the estimated space area;

[0079] Step S402, judging whether the curtain occupies the entire estimated space area according to the curtain position; if yes, executing step S403

[0080] Step S403, when the curtain occupies the entire estimated space area, control the bracket to move to the target position.

[0081] Specifically, generally speaking, curtains may occupy all or part of the estimated space area. When they occupy the entire space, and the estimated space area overlaps with the air inlet area, the curtains will inevitably be in the air inlet area, and the probability of blocking the air inlet is very high. Therefore, it is necessary to use a bracket to block the front of the air inlet, thereby blocking the curtains outside.

[0082] Figure 8 According to another specific embodiment of the present invention, a schematic flowchart of the steps of controlling the bracket to move to the target position when the air inlet area overlaps with the estimated space area; as another specific embodiment of the present invention, in step S402 of this embodiment, after the step of determining whether the curtain occupies the entire estimated space area according to the curtain position, further includes:

[0083] Step S4021, when the curtain does not occupy the entire estimated space area, determine whether the edge of the curtain is located in the air inlet area; if so, execute step S403, otherwise end.

[0084] In this embodiment, since the curtains do not necessarily occupy the entire estimated space area all the time during use, but may change during use, when the curtains do not occupy the entire estimated space area, the edge position of the curtains can be obtained to determine whether the edge position of the curtains is in the air inlet area. When the edge position of the curtains is still in the air inlet area, there is still a certain probability that the curtains will be pushed to the air inlet due to the air flow channel of the air inlet, thereby blocking the air inlet of the air conditioner, affecting the normal use of the air conditioner.

[0085] Generally speaking, the recognition of whether the curtain occupies the estimated space area and the edge of the curtain can be obtained by a camera installed at the air conditioner. After the camera obtains the image of the curtain, it will combine the previously obtained data of the air inlet area and the estimated space area for calculation and processing, and then obtain whether the curtain occupies the entire area of ​​the estimated space area and the location of the edge of the curtain.

[0086] Fig. 9 According to another specific embodiment of the present invention, a schematic flowchart of the steps of controlling the bracket to move to the target position when the air inlet area overlaps with the estimated space area; as a specific embodiment of the present invention, in step S4021, when it is determined that the curtain does not occupy the entire estimated space area, the step of determining whether the edge of the curtain is located in the air inlet area includes:

[0087] Step S4023, when the edge of the curtain is located in the air inlet area, obtaining the air volume of the air inlet;

[0088] Step S4024, judging whether it is necessary to control the bracket to move to the target position according to the wind volume and the preset wind volume threshold.

[0089] In this embodiment, even if the edge of the curtain is in the air inlet area, the air volume at the air inlet has a great influence on whether the curtain will be adsorbed at the air inlet. It does not mean that the edge of the curtain will be adsorbed at the air inlet just because it is in the air inlet area. In this embodiment, the air volume at the air inlet can be directly detected by the air volume sensor set at the air inlet position, or it can be calculated based on various parameters of the air conditioner. Generally speaking, the air volume at the air inlet of the air conditioner corresponding to different modes and different wind speeds of the air conditioner is certain, so the air volume at the air inlet can be obtained according to the mode and wind speed of the air conditioner at the moment.

[0090] In this embodiment, when the edge of the curtain is at the air inlet area, the air volume of the air inlet is also detected to determine whether the curtain will block the air inlet, thereby eliminating the situation where the energy consumption increases due to controlling the bracket to move to the target area regardless of whether the curtain will block it.

[0091] Fig.10 According to another specific embodiment of the present invention, when the air intake area overlaps with the estimated space area, a schematic flow chart of the steps of controlling the bracket to move to the target position is provided. As a specific embodiment of the present invention, step S4024 of this embodiment, the step of determining whether it is necessary to control the bracket to move to the target position according to the air volume and the preset air volume threshold, includes:

[0092] Step S4025, subtracting the air volume from the preset air volume threshold to obtain an air volume difference;

[0093] Step S4026, comparing the air volume difference with the difference threshold;

[0094] Step S4027, when the difference is greater than the difference threshold, control the bracket to move to the target position.

[0095] In this embodiment, the difference is obtained by using the air volume and the preset air volume threshold. When the difference is greater than the difference threshold, it means that the air volume at the air inlet of the air conditioner is large at this moment, which is sufficient to adsorb the curtains at the air inlet. Therefore, it is necessary to control the bracket to prevent the curtains from being adsorbed at the air inlet by the air inlet, so as to avoid affecting the use of the air conditioner.

[0096] The control method of the anti-shielding bracket of the indoor unit of the air conditioner in this embodiment combines the judgment and comparison of whether the air inlet area overlaps with the estimated space area, whether the curtain occupies the entire estimated space area, whether the edge of the curtain is located in the air inlet area and the amount of air at the air inlet, so as to accurately control the movement of the bracket, avoid the bracket being always at the air inlet affecting the appearance of the air conditioner and the air intake of the air inlet, and also improve the accuracy as much as possible, so that most of the curtains that may block the air inlet are blocked by the bracket, ensuring the normal use of the air conditioner.
