Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of air conditioners, and specifically provides an air conditioner and a control method thereof. BACKGROUND

[0002] In the prior art, when an air conditioner is cooling, the rotation of the fan is generally controlled according to the temperature of the room in which the air conditioner is located. That is, when the temperature of the room is higher than the set temperature of the air conditioner, the fan of the air conditioner rotates; when the temperature of the room decreases to the set temperature of the air conditioner, the fan of the air conditioner stops rotating. The higher the temperature of the room, the faster the rotation speed of the fan; the lower the temperature of the room, the lower the rotation speed of the fan.

[0003] The prior art air conditioner cannot automatically match the rotation speed of the fan to the size of the room. For a room with a small space, when the fan operates at a high rotation speed, the temperature of the room is rapidly lowered, which easily causes the user to catch a cold. SUMMARY

[0004] An object of the present application is to solve the problem that the prior art air conditioner cannot automatically match the rotation speed of the fan to the size of the room.

[0005] A further object of the present application is how to obtain the heat load of the room.

[0006] A still further object of the present application is how to realize the non-sensible blowing of the air conditioner.

[0007] To achieve the above objects, the present application provides, in a first aspect, a control method of an air conditioner, comprising:

[0008] determining the user heat load of a user in the room;

[0009] determining the target rotation speed of the fan of the air conditioner according to the user heat load and the room heat load;

[0010] controlling the fan to operate at the determined target rotation speed.

[0011] Optionally, before the step of determining the target rotation speed of the fan of the air conditioner, the control method further comprises:

[0012] obtaining the current weather;

[0013] determining the room heat load of the room from a pre-stored weather-heat load table according to the current weather.

[0014] Optionally, the weather-heat load table comprises a plurality of weathers and a room heat load corresponding to each weather, and the room heat load corresponding to each weather is obtained as follows:

[0015] control the air conditioner to cool the room when detecting that the room is empty;

[0016] determine a total cooling amount of the air conditioner in the preset time length when the room is lowered to the preset temperature and maintained for the preset time length;

[0017] calculate a quotient value between the total cooling amount and the preset time length, and take the quotient value as the room heat load.

[0018] Optionally, the determining the target rotating speed of the fan of the air conditioner according to the user heat load and the room heat load comprises:

[0019] calculating a sum of the user heat load and the room heat load, and taking the sum as a total heat load;

[0020] determining the target rotating speed according to the total heat load and a heat load-rotating speed mapping relationship.

[0021] Optionally, the control method further comprises:

[0022] determining a current position of a user in the room;

[0023] determining a man-machine distance between the current position and the air conditioner;

[0024] determining whether a farthest distance of air blown by the air conditioner running at the target rotating speed is greater than the man-machine distance;

[0025] if greater, updating the target rotating speed to a fan rotating speed corresponding to the man-machine distance.

[0026] Optionally, the control method further comprises:

[0027] determining a swing frequency of a swing leaf of the air conditioner according to the total heat load and a heat load-swing frequency mapping relationship;

[0028] controlling the swing leaf to swing at the determined swing frequency.

[0029] Optionally, the determining the user heat load of the user in the room comprises:

[0030] obtaining an image at a position where the user is located;

[0031] determining a number of users according to the image;

[0032] determining the user heat load according to the number of users and a preset heat load of a human body.

[0033] Optionally, the control method further comprises:

[0034] detecting the humidity in the room in real time;

[0035] when the humidity is less than the preset humidity, starting a humidifier of the air conditioner.

[0036] The application provides an air conditioner in a second aspect, comprising a controller, a memory and execution instructions stored on the memory, the execution instructions being configured to enable the air conditioner to execute the control method of any one of the first aspect when executed by the controller.

[0037] Optionally, the air conditioner further comprises a humidifier configured to receive and hold the condensed water of the air conditioner and configured to spray water mist generated thereby towards an air outlet of the air conditioner.

[0038] Based on the foregoing description, those skilled in the art can understand that, in the technical solutions of the foregoing aspects of the application, the target rotating speed of the fan of the air conditioner is determined based on the user heat load and the room heat load, and the fan is caused to operate at the determined target rotating speed, so that the air conditioner can control the rotating speed of the fan according to the heat load in the room.

[0039] Those skilled in the art can also understand that, according to the need, since the larger the room is, the higher the heat load of the room is, the application can indirectly match the size of the room and control the fan to operate at the corresponding rotating speed (i.e., the target rotating speed) according to the heat load, as compared with the prior art in which the rotating speed of the fan is controlled based on the temperature in the room. Therefore, the application avoids the temperature of a room with a small space being rapidly lowered by the air conditioner when the cooling efficiency is high, thereby improving the comfort of the user.

[0040] Further, the application determines the current weather, and then determines the room heat load of the room from the pre-stored weather-heat load table, so that the current room heat load is more accurate, and the rotating speed of the fan is prevented from being too high or too low.

[0041] Further, when it is detected that there is no one in the room, the air conditioner is controlled to cool the room, and when the room is lowered to the preset temperature and maintained for the preset time length, the total cooling amount of the air conditioner in the preset time length is determined, and then the quotient between the total cooling amount and the preset time length is calculated to take the quotient as the room heat load. Therefore, the application can also enable the air conditioner to automatically calculate the room heat load for each kind of weather, and is more intelligent.

[0042] Still further, whether the farthest distance of the air blown by the air conditioner at the target rotating speed is greater than the man-machine distance is judged, and when it is greater, the target rotating speed is updated to the fan rotating speed corresponding to the man-machine distance, so that the air conditioner is prevented from blowing to the user, thereby realizing the air conditioner blowing without feeling.

[0060] Those skilled in the art will understand that the embodiments described below are merely a part of the embodiments of the present application, rather than all the embodiments of the present application, and are intended to explain the technical principles of the present application, rather than limit the protection scope of the present application. Based on the embodiments provided by the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort shall fall within the protection scope of the present application.

[0061] It should be noted that, in the description of the present application, the terms "center", "upper", "lower", "top", "bottom", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicating the direction or positional relationship are based on the direction or positional relationship shown in the drawings, which is merely for the convenience of description, and does not indicate or imply that the device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first", "second", "third" are only for descriptive purposes, and cannot be understood as indicating or implying relative importance.

[0062] Further, it should be noted that, in the description of the present application, unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connection" should be understood broadly, for example, can be fixed connection, can also be detachable connection, or integrally connected; can be mechanical connection, can also be electrical connection; can be directly connected, can also be indirectly connected through an intermediate medium, or can be the communication between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0063] In addition, it should be noted that, in the description of the present application, the terms "cold" and "heat" are two descriptions of the same physical state. That is, the higher the "cold" of a certain target (such as an evaporator, air, a condenser, etc.), the lower the "heat" it has, and the lower the "cold" it has, the higher the "heat" it has. A certain target absorbs "cold" while releasing "heat", and releases "cold" while absorbing "heat". A certain target saves "cold" or "heat" to keep the target at the current temperature. "Refrigeration" and "heat absorption" are two descriptions of the same physical phenomenon, that is, a certain target (such as an evaporator) absorbs heat while refrigerating.

[0064] Finally, it needs to be explained that in the description of the present application, each functional module can be a physical module composed of multiple structures, components or electronic elements, or a virtual module composed of multiple programs; each functional module can be a module that exists independently of each other, or a module divided by a whole module according to function. It should be understood by those skilled in the art that the constituting manner, implementation manner and positional relationship of each functional module can be changed in any way as long as the technical solutions described in the present application can be realized, and therefore all should fall within the protection scope of the present application.

[0065] In the present application, the air conditioner can be any feasible air conditioner, such as a cabinet air conditioner, a hanging air conditioner, a central air conditioner, a card air conditioner, etc.

[0066] As shown in Figure 1 , in the first embodiment of the present application, the control method of the air conditioner comprises:

[0067] Step S110, determining the user heat load of the user in the room.

[0068] As an example one, as shown in Figure 2 , step S110 further comprises:

[0069] Step S111, acquiring the image at the position where the user is located.

[0070] As shown in Figure 3 , the air conditioner 100 comprises a camera module 110, so that the air conditioner 100 acquires the image through the camera module 110.

[0071] Specifically, the air conditioner 100 can take a picture of the room through the camera module 110 to acquire the image at the position where the user is located.

[0072] Step S112, determining the number of users according to the image.

[0073] Specifically, through image recognition technology, the user in the image and the number of users are recognized.

[0074] Step S113, determining the user heat load according to the number of users and the preset heat load of the human body.

[0075] For a general adult, the heat load at rest is about 100W, and the heat load when exercising is 200-300W. In the present application, the preset heat load is selected from any value between 80W and 200W, such as 100W, 120W, 125W, etc.

[0076] Specifically, the user heat load of the user in the room is the product of the number of people and the preset heat load.

[0077] As an example two, the camera module 110 comprised by the air conditioner 100 is an infrared camera module, and the air conditioner 100 determines the user heat load of the user according to the pixel value of the user in the infrared image captured by the infrared camera module of the air conditioner 100.

[0078] Step S120, according to the user heat load and the room heat load, determine the target rotating speed of the fan 120 of the air conditioner 100.

[0079] The room heat load can be data pre-stored in the air conditioner 100, or data obtained by the air conditioner 100 through a cloud server or a background server. In addition, the room heat load can be a fixed value or a variable value.

[0080] When the air conditioner 100 obtains data through a cloud server or a background server, the user needs to send the volume of the room where the air conditioner 100 is located to the cloud server or the background server, so that the cloud server or the background server matches the room heat load corresponding to the volume.

[0081] As shown in Figure 4 Step S120 further comprises:

[0082] Step S121, calculate the sum of the user heat load and the room heat load, and mark it as the total heat load;

[0083] Step S122, according to the total heat load and the heat load-rotating speed mapping relationship, determine the target rotating speed.

[0084] The heat load-rotating speed mapping relationship is as follows:

[0085] In example one, the rotating speed is marked as R, and the heat load is marked as Q, then R=k×Q. Wherein k is the conversion coefficient, and the specific value can be obtained by multiple tests. For example, k can be 9, 25, 100, 133, etc.

[0086] In example two, the heat load-rotating speed mapping relationship is as shown in Figure 5

[0087] Step S130, control the fan 120 to operate according to the determined target rotating speed.

[0088] Based on the foregoing description, those skilled in the art can understand that in the first embodiment of the present application, the target rotating speed of the fan 120 of the air conditioner 100 is determined by the user heat load and the room heat load, and the fan 120 operates according to the determined target rotating speed, so that the air conditioner 100 can control the rotating speed of the fan 120 according to the heat load in the room.

[0089] ​The person skilled in the art can also match the size of the room indirectly and automatically through the heat load and control the fan 120 to operate at the corresponding speed (i.e. the target speed) according to the need, since the larger the space of the room is, the higher the heat load of the room is; compared to the prior art in which the speed of the fan 120 is controlled through the temperature in the room. Therefore, the air conditioner 100 of the present application avoids rapidly lowering the temperature of the room with a smaller space when the cooling efficiency is high, thereby improving the comfort of the user.

[0090] As shown in FIG. 2, in the second embodiment of the present application, the control method of the air conditioner further comprises the following steps before step S120, which is different from the first embodiment. Figure 6

[0091] Step S210, obtaining the current weather.

[0092] Further, in the second embodiment of the present application, the air conditioner 100 further comprises a wireless communication module, so as to connect the Internet through the wireless communication module, thereby obtaining the current weather of the local through the Internet.

[0093] Step S220, determining the room heat load of the room from the pre-stored weather-heat load table according to the current weather.

[0094] As shown in FIG. 3, the weather-heat load table is shown. It should be noted that, Figure 7 Figure 7 only the corresponding conditions of the weather-heat load are schematically shown to help the person skilled in the art understand the technical solutions of the present application. The person skilled in the art can increase or decrease the number of items in the table shown in Figure 7

[0095] As can be seen from Figure 7 , the weather-heat load table includes a plurality of weather and the room heat load corresponding to each weather.

[0096] Further, Figure 7 Q1 to Q16 (i.e. the room heat load corresponding to each weather) in

[0097] Step S201, when detecting that there is no one in the room, controlling the air conditioner 100 to cool the room.

[0098] Step S202, when the room is lowered to the preset temperature and maintained for a preset time, determining the total cooling amount of the air conditioner 100 within the preset time.

[0099] ​​​The preset temperature is a temperature set by a user for the air conditioner 100 or a temperature pre-stored in the air conditioner 100, which can be any feasible value, for example, 17℃, 20℃, 21℃, 25℃, etc. The preset time length can be any feasible time length, for example, 10 minutes, 30 minutes, 1 hour, etc.

[0100] Further, the total refrigeration capacity can be obtained in any feasible manner. For example, by the flow rate of air flowing through the air conditioner 100 and the temperature difference of the air at the air inlet and outlet of the air conditioner 100. Since the technical means for obtaining the total refrigeration capacity of the air conditioner 100 is a common technical means known to those skilled in the art, no detailed description is given here.

[0101] In step S203, a quotient between the total refrigeration capacity and the preset time length is calculated, and the quotient is taken as the room heat load.

[0102] Those skilled in the art can understand that when the room is reduced to the preset temperature and maintained at the preset temperature, it means that the refrigeration capacity of the air conditioner 100 is equal to the heat generation capacity of the room. Taking the quotient between the total refrigeration capacity in the preset time length and the preset time length as the room heat load can make the determined room heat load more accurate and avoid the unreliability of the start and stop of the fan 120.

[0103] Further, Figure 7 Q1 to Q16 in the table (i.e., the room heat load corresponding to each kind of weather) can also be obtained by the air conditioner 100 from a cloud server or a background server through the Internet.

[0104] When the air conditioner 100 obtains from the cloud server or the background server, the user needs to send the size or volume of the room where the air conditioner 100 is located to the cloud server or the background server, so that the cloud server or the background server matches to the room size corresponding to the size or volume. That is, the weather-heat load table stored on the background cloud server or the background server also includes room size data.

[0105] Based on the foregoing description, those skilled in the art can understand that in the second embodiment of the present application, by determining the current weather and then determining the room heat load of the room from the pre-stored weather-heat load table, the current room heat load is more accurate, and the rotation speed of the fan 120 is avoided to be too high or too low.

[0106] Further, when it is detected that there is no one in the room, the air conditioner 100 is controlled to cool the room, and when the room is reduced to the preset temperature and maintained for the preset time length, the total refrigeration capacity of the air conditioner 100 in the preset time length is determined; then a quotient between the total refrigeration capacity and the preset time length is calculated, and the quotient is taken as the room heat load. Therefore, the air conditioner 100 can also automatically calculate the room heat load for each kind of weather, which is more intelligent.

[0107] As shown in FIG. 3, in the third embodiment of the present application, compared with the first embodiment and the second embodiment, the control method of the air conditioner further comprises: Figure 8

[0108] Step S310, determining the current position of the user in the room.

[0109] As an example one, the image of the room can be acquired by the camera module 110 described above, and then the user in the image is recognized, and the position of the user relative to the air conditioner 100 is determined accordingly.

[0110] As an example two, the air conditioner 100 receives the sound emitted by the user, and determines the current position of the user according to the received sound. Specifically, the air conditioner 100 further comprises a sonar or a sound recognition module, so as to receive the sound emitted by the user through the sonar or the sound recognition module, and determine the current position of the user through the sound.

[0111] Step S320, determining the human-machine distance between the current position and the air conditioner 100.

[0112] As an example one, if the air conditioner 100 comprises a sonar, the human-machine distance between the current position and the air conditioner 100 can be determined through the sonar while the current position of the user is recognized.

[0113] As an example two, the air conditioner 100 further comprises a ranging device, so as to measure the human-machine distance between the current position and the air conditioner 100 through the ranging device. The ranging device can be a laser ranging device.

[0114] Step S330, determining whether the farthest distance of the air blown by the air conditioner 100 running at the target rotating speed is greater than the human-machine distance.

[0115] Specifically, the farthest distance of the air blown by the air conditioner 100 running at the target rotating speed is determined from the pre-stored rotating speed-air blowing distance table (as shown in FIG. 4), and then the farthest distance is compared with the human-machine distance. Figure 9

[0116] Wherein, the rotating speed-air blowing distance table is pre-stored in the air conditioner 100 before the air conditioner 100 is shipped. The relationship between the rotating speed of the fan and the air blowing distance of the air conditioner 100 can be obtained through experiments, which will not be described here.

[0117] Step S340, if greater, the target rotating speed is updated to the rotating speed of the fan corresponding to the human-machine distance.

[0118] Correspondingly, if less than or equal to, the target rotating speed remains unchanged.

[0119] ​​The skilled in the art can understand that in the third embodiment of the present application, by judging whether the farthest distance of the air blown by the air conditioner 100 running at the target rotating speed is greater than the man-machine distance, and updating the target rotating speed to the fan rotating speed corresponding to the man-machine distance when it is greater, the air conditioner 100 is prevented from blowing air to the user, so that the air conditioner 100 realizes the no-sense air supply.

[0120] As shown in Figure 10 , in the fourth embodiment of the present application, the air conditioner 100 further comprises a swing leaf 130 (an air deflector). The swing leaf 130 comprises at least one of a vertical swing leaf and a horizontal swing leaf.

[0121] As shown in Figure 11 , in the fourth embodiment of the present application, compared with any of the above-described embodiments, the control method of the air conditioner further comprises:

[0122] Step S410, determining the swing frequency of the swing leaf 130 of the air conditioner 100 according to the total heat load and the heat load-swing frequency mapping relationship.

[0123] The heat load-swing frequency mapping relationship is as follows:

[0124] Example one, let the swing frequency be f, and the heat load be Q, then f = j x Q. Wherein j is a conversion coefficient, and the specific value can be obtained by multiple tests. For example, j can be 0.5, 2, 7, 11, etc.

[0125] Example two, the heat load-swing frequency mapping relationship is set as a mapping table similar to Figure 5 . The swing frequency in the mapping table can be determined according to experience.

[0126] Step S420, controlling the swing leaf 130 to swing according to the determined swing frequency.

[0127] In the fourth embodiment, if the farthest distance of the air blown is greater than the man-machine distance, the target rotating speed is updated to the fan rotating speed corresponding to the man-machine distance when the swing leaf 130 swings to make the cold air blow to the user. If the swing leaf 130 does not swing to make the cold air blow to the user, the fan 120 continues to rotate at the target rotating speed.

[0128] As shown in Figure 12 , in the fifth embodiment of the present application, compared with any of the above-described embodiments, the air conditioner 100 further comprises a humidifier 140. The humidifier 140 is configured to be able to receive and contain the condensed water of the air conditioner 100, and to be able to spray the water mist generated thereby to the air outlet of the air conditioner 100.

[0129] Furthermore, the humidifier 140 includes a container and an atomizer. The container is connected to a water tray inside the air conditioner 100 for collecting condensate, and the inner bottom wall of the container is lower than the bottom wall of the water tray, while the top wall of the container is higher than the top of the water tray, so that the condensate in the water tray can automatically flow to the container. When the atomizer is powered on, it can atomize the water in the container.

[0130] Preferably, the atomizer or the corresponding air outlet of the atomizer is located at the air outlet of the air conditioner 100.

[0131] like Figure 13 As shown, in the fifth embodiment of the present invention, the air conditioner control method further includes, relative to any of the embodiments described above:

[0132] Step S510: Real-time detection of humidity in the room.

[0133] Specifically, the air conditioner 100 is also equipped with a humidity sensor for detecting room humidity, so that the air conditioner 100 can detect the humidity in the room through the humidity sensor.

[0134] In step S520, when the humidity is lower than the preset humidity, the humidifier 140 of the air conditioner 100 is turned on, so that the air conditioner 100 humidifies the room and prevents the room from becoming too dry.

[0135] like Figure 14 As shown, in the sixth embodiment of the present invention, compared with any of the embodiments described above, the air conditioner 100 further includes a controller 150 and a memory 160.

[0136] In this embodiment, the memory 160 is used to store execution instructions, which are specifically executable computer programs. Furthermore, the execution instructions stored in the memory 160 are configured to enable the air conditioner to perform the control method described in any of the preceding embodiments when executed by the controller 150.

[0137] In this embodiment, the memory 160 may include main memory and non-volatile memory, and provides execution instructions and data to the controller 150. Exemplarily, the main memory may be high-speed random-access memory (RAM), and the non-volatile memory may be at least one disk storage device.

[0138] In the present embodiment, the controller 150 is an integrated circuit chip having the ability to process signals. The controller 150 can be a general-purpose processor, such as a central processing unit (CPU), a network processor (NP), a digital signal processor (DSP), an application specific integrated circuit (ASIC), a field-programmable gate array (FPGA) or other programmable logic device, discrete gate or transistor logic, discrete hardware components, a microprocessor, and other any conventional processor.

However, those skilled in the art can easily understand that the protection scope of the present application is not limited to these specific embodiments.
