[0053] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0054] It should be noted that the terms "first", "second", etc. in the specification of the present invention and the above-mentioned drawings are used to distinguish similar users, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0055] The following is a detailed description of an embodiment of the method for locating indoor heat sources in an air conditioner according to the present invention. Figure 1 As shown, it is a flow chart of the method for locating indoor heat sources of air conditioners provided by the present invention, and the specific implementation process includes the following steps:

[0056] Step 101: When the indoor air conditioner supplies air to multiple sectors divided within the target area in sequence according to a preset scanning mode, obtain the first air outlet temperature of the air outlet and the first return air temperature of the return air outlet corresponding to each sector when the indoor air conditioner is in operation, and determine the first temperature difference between the first air outlet temperature and the first return air temperature.

[0057] In the embodiment of the present invention, before executing this step, it is necessary to trigger the indoor air conditioner to perform initialization operation in advance when the indoor air conditioner is installed and there is no moving object (such as a moving human body) in the target area (such as an indoor space), so as to scan the multiple sectors divided in the target area one by one in sequence, and obtain the initial first background temperature difference corresponding to each sector in the target area; and scan the multiple sub-sectors divided in each sector one by one in sequence, and obtain the initial second background temperature difference corresponding to each sub-sector in each sector; and store the first background temperature difference and the second background temperature difference as reference temperature difference values, so as to serve as the reference temperature difference value for comparison reference in the subsequent actual positioning process. The first background temperature difference value is the reference temperature difference value corresponding to each sector obtained by scanning each sector in the target area one by one when the indoor air conditioner performs initialization operation after installation.

[0058] That is, if Figure 4 As shown, after the indoor air conditioner is initially installed, it is initialized and operated when no one is in the room, and the scanning operation is performed sector by sector and distance by distance, and the initial temperature difference value measured is recorded as the background temperature difference value. The background temperature difference value includes a first background temperature difference value and a second background temperature difference value.

[0059] It should be noted that, when the indoor air conditioner is installed and there is no moving object in the target area, before triggering the indoor air conditioner to initialize operation, it is necessary to divide the target area and mark multiple corresponding sectors in advance, such as Figure 2 The sectors are divided into sectors "1" and "2". The sectors are divided and labeled into a plurality of corresponding sub-sectors, such as Figure 2 The "one" sector shown in the figure has four sub-sectors 1, 2, 3, and 4. The size of the sector corresponds to the left and right air outlet angle of the air guide plate at the air outlet of the indoor air conditioner, for example Figure 2 The larger the left and right air outlet angle formed by the air guide plate, the larger the area of ​​the formed sector, and the smaller the left and right air outlet angle formed by the air guide plate, the smaller the area of ​​the corresponding sector. The size of the sub-sector corresponds to the size of the upper and lower air outlet angle of the air guide plate at the air outlet of the indoor air conditioner, for example Figure 2 The larger the upper and lower air outlet angles formed by the air guide plate are, the larger the area of ​​the corresponding sub-sector is, and the smaller the upper and lower air outlet angles formed by the air guide plate are, the smaller the area of ​​the corresponding sub-sector is.

[0060] Accordingly, the indoor air conditioner (i.e. Figure 2The air conditioner shown in the figure supplies air to the multiple sectors divided in the target area in sequence according to the preset scanning mode. The corresponding specific implementation process includes: triggering the indoor air conditioner to supply air to the multiple sectors divided in the target area in sequence based on the preset sector scanning sequence and sector stay air supply time. That is, the scanning mode may include the preset scanning sequence and scanning time performed by the indoor air conditioner for the multiple sectors, such as Figure 2 As shown, the scanning order is to scan from sector "1" to sector "2", and the scanning sequence is to stay in sector "1" for eight minutes (i.e., the scanning time corresponding to sector "1"), and stay in sector "2" for eight minutes (i.e., the scanning time corresponding to sector "2"). Furthermore, when scanning sector "1", the indoor air conditioner is scanned from near to far, i.e., from 1 to 4 (i.e., the indoor air conditioner is scanned from near to far, i.e., from 1 to 4). Figure 3 As shown), the scanning time corresponding to each sub-sector is 2 minutes, but of course no specific limitation is made here.

[0061] During the implementation of the steps, the actual operation of the indoor air conditioner can be detected. When the indoor air conditioner supplies air to multiple sectors divided in the target area in sequence according to the preset scanning mode, the first outlet air temperature of the air outlet and the first return air temperature of the return air outlet corresponding to each sector are obtained, and the first temperature difference between the first outlet air temperature and the first return air temperature is determined. That is, during the process of the indoor air conditioner scanning and supplying air to the "one" sector and the "two" sector, the difference between the first outlet air temperature of the air outlet and the first return air temperature of the return air outlet is different. For example, if there is a heat source in the "one" sector and there is no heat source in the "two" sector, the difference between the first outlet air temperature of the air outlet and the first return air temperature of the return air outlet is usually larger when scanning and supplying air to the "one" sector, and the difference between the first outlet air temperature of the air outlet and the first return air temperature of the return air outlet is usually smaller when scanning and supplying air to the "two" sector. The human body is equivalent to a heat source, and the heat source includes the human body or other objects that generate heat.

[0062] Step 102: Compare the first temperature difference with a preset first background temperature difference to obtain a first comparison result, and determine the target sector where the heat source is located in the target area according to the first comparison result; wherein the first background temperature difference is an initial reference temperature difference obtained by scanning each sector in the target area one by one after the indoor air conditioner is installed.

[0063] Specifically, the first temperature difference is compared with a preset first background temperature difference to obtain a corresponding first deviation value, and when the first deviation value reaches or exceeds a preset first target deviation value, the sector corresponding to the first temperature difference is determined as the target sector where the heat source is located. The sector corresponding to the first temperature difference is the same as the sector corresponding to the first background temperature difference.

[0064] Furthermore, after determining the target sector where the heat source is located in the target area according to the first comparison result, the operating wind speed of the indoor air conditioner and the up and down rotation position of the air guide plate at the air outlet can be adjusted according to the preset control parameters to perform a subdivision scan from near to far on the target sector (such as Figure 3 As shown), to determine the second outlet air temperature of the air outlet and the second return air temperature of the return air outlet corresponding to each sub-sector in the target sector when the indoor air conditioner is running, and determine the second temperature difference between the second outlet air temperature and the second return air temperature. The second temperature difference is compared with the preset second background temperature difference to obtain a second comparison result, and the target sub-sector where the heat source in the target area is located is determined according to the second comparison result. Among them, the second background temperature difference is the initial reference temperature difference obtained by scanning each sub-sector in the target area one by one after the indoor air conditioner is installed. The first target deviation value and the second target deviation value can be the same or different.

[0065] Among them, the second temperature difference is compared with the preset second background temperature difference to obtain a second comparison result, and the target sub-sector where the heat source is located in the target area is determined according to the second comparison result. The corresponding specific implementation process includes: comparing the second temperature difference with the preset second background temperature difference to obtain a corresponding second deviation value, and when the second deviation value reaches or exceeds the preset second target deviation value, determining the sub-sector corresponding to the second temperature difference as the target sub-sector where the heat source is located. The sector corresponding to the second temperature difference is the same as the sub-sector corresponding to the second background temperature difference. That is, Figure 5 As shown, when scanning the heat source, the air supply is scanned zone by zone, the temperature difference (ie, the first temperature difference or the second temperature difference) is recorded and compared with the initial record (ie, the first background temperature difference or the second background temperature difference), and the heat source position is marked.

[0066] It should be noted that in order to avoid the influence of ambient temperature changes on the results, the background temperature difference records the temperature difference between the outlet air and the return air. When there is a heat source in the sector or sub-sector of the target area currently being scanned, the return air temperature of the corresponding sector or sub-sector becomes higher, and the temperature difference between the outlet air and the return air becomes larger; when there is no heat source in the sector or sub-sector of the target area currently being scanned, the outlet air and the return air temperature change little, and the size of the heat source can be further judged according to the size of the temperature difference. Furthermore, after confirming the sector where the heat source is located, the current sector is subdivided and scanned from near to far by adjusting the wind speed and the upper and lower positions of the air outlet. When the return air temperature difference (the first temperature difference or the second temperature difference) deviates greatly from the initial temperature difference (i.e., the background temperature difference), the distance to the heat source can be confirmed. By comparing the temperature difference from near to far by wind direction, when the air outlet is farther away, it may contain a nearby heat source, so the distance to the heat source can be confirmed from near to far.

[0067] In addition, in the improved plan, in order to further speed up the confirmation of the heat source, the air outlet angle can be increased (that is, the air outlet angle formed by the upper and lower air guide plates), and the left and right half areas can be scanned separately. After confirming that the heat source is in a certain half area, this half area can be further divided into two halves, and the air outlet angle can be reduced, and then scanned separately until the smallest sector where the heat source is located is confirmed.

[0068] In addition, during the operation of the indoor unit of the air conditioner, people may move or their movement status may change, such as changing from sitting to lying down, or from moving to still. The change can be detected in time through the temperature difference between the outlet and return air, and the heat source position can be re-scanned to adjust the target cooling area. This method can change the air conditioner's flooding cooling to precise cooling, which not only meets the comfort requirements but also achieves energy-saving effects.

[0069] The present invention can accurately locate the indoor heat source by measuring the air outlet temperature, return air temperature, air outlet angle and other parameters without increasing the air conditioning cost, so as to prepare for the subsequent intelligent control. After determining the target sub-sector where the heat source is located in the target area according to the second comparison result, the target sub-sector can be determined as the target cooling area of ​​the indoor air conditioner to control the indoor air conditioner to supply air to the target cooling area, and the heat source can be quickly confirmed in the shortest time, and the temperature can be reduced for the heat source, which shortens the response time, realizes accurate cooling and saves energy.

[0070] At present, there is an infrared sensing method to complete heat source positioning, and the positioning data obtained is two-dimensional data, but the 3D data of the heat source cannot be obtained, and the price is high and cannot be popularized. The indoor heat source positioning method of the air conditioner provided by the present invention obtains the outlet air temperature of the air outlet and the return air temperature of the return air outlet corresponding to each sector when the indoor air conditioner supplies air to multiple sectors divided in the target area, and determines the temperature difference between the outlet air temperature and the return air temperature; compares the temperature difference with the preset background temperature difference to obtain the comparison result, and determines the target sector where the heat source in the target area is located according to the comparison result, which can quickly confirm the heat source, improve the efficiency and accuracy of the indoor heat source positioning of the air conditioner, and effectively reduce the power consumption.
