In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
The invention provides an air conditioner control method. The control method can be particularly used for a hot air type air source heat pump air conditioner. For example, a floor-standing air-source heat pump air conditioner is preferable. The air conditioner is provided with the heating plate, namely, heating is realized by converting electric energy into heat energy. For example, a heating panel is provided outside a panel of the air conditioner. The heating plate may be detachable. Preferably, the heating plate is a carbon crystal heating plate. The carbon crystal heating plate generates molecular motion between internal carbon atoms and generates violent friction and impact to generate a large amount of heat energy, the conversion rate of electric energy and the heat energy is up to more than 98%, and the carbon crystal heating plate is combined with a floor type air source heat pump air conditioner, so that the problem of delay in heat supply of the conventional air source heat pump air conditioner can be effectively solved, and the instant heating is realized.
Fig. 1 is a schematic method diagram of an embodiment of an air conditioner control method provided by the present invention.
As shown in fig. 1, according to an embodiment of the present invention, the air conditioner control method includes at least step S110 and step S120.
And step S110, after the air conditioner is heated and started and before the indoor fan is started, controlling the heating plate to be opened.
Specifically, when the air conditioner is started in the heating mode, the temperature of the inner pipe of the indoor unit is low, and the inner fan cannot be started at the moment in order to prevent cold air from being blown out. Therefore, after the air conditioner is heated and started, when the inner fan is not started, the heating plate is controlled to be opened so as to set the heating power for heating. Because the heating plate can realize instant heating, the user can quickly heat when the user has the demand of instant heating, for example, the user can immediately heat when entering the room from the cold outdoor.
And step S120, after the indoor fan is started, adjusting the heating power of the heating plate or controlling the heating plate to be closed according to the distance between the user in the room and the heating plate and/or the body surface temperature of the user in the room.
Specifically, when the indoor fan is started and hot air starts to be blown out, the distance between a user in a room and the heating plate and/or the body surface temperature of the user in the room are acquired, and the heating power of the heating plate is adjusted or the heating plate is controlled to be closed according to the distance between the user in the room and the heating plate and/or the body surface temperature of the user in the room.
For example, the distance from the heating plate to the user in the room and/or the body surface temperature of the user in the room can be collected by an infrared human body detection sensor arranged outside the air conditioner. For example, the distance of the user from the heating plate is calculated from the time difference between the emission of the infrared signal and the reception of the user (human body) reflection signal.
Fig. 2 is a schematic flow chart of an embodiment of the step of adjusting the heating power of the heating plate or controlling the heating plate to be closed according to the distance between the user in the room and the heating plate and/or the body surface temperature of the user in the room. As shown in fig. 2, in a specific embodiment, step S120 includes step S121, step S122, and step S123.
Step S121, judging whether the distance between the user in the room and the heating plate is larger than or equal to a preset distance threshold value.
The preset distance threshold value can be specifically a distance value between a human body which enables the human body to feel comfortable and the heating plate.
And S122, if the distance is larger than or equal to the preset distance threshold, adjusting the heating power of the heating plate or controlling the heating plate to be closed according to the difference value between the distance and the preset distance threshold.
Specifically, if the difference between the distance and the preset distance threshold is greater than a first preset value, the heating power of the heating plate is increased to a second heating power value; and if the difference value between the distance and the preset distance threshold is greater than a second preset value or no human body exists in the room, closing the heating plate. Wherein the first preset value is smaller than the second preset value.
More specifically, if the difference between the distance and the preset distance threshold is greater than the first preset value, which indicates that the user is far away from the heating plate, the heating power of the heating plate needs to be properly increased, and the heating power of the heating plate can be increased to a second heating power value (which does not exceed the upper limit value of the heating power), so as to compensate the temperature of the user, and make the user feel comfortable. If the difference value between the distance and the preset distance threshold is larger than a second preset value, it indicates that the distance between the user and the heating plate is too far and exceeds the effective heat radiation range of the heating plate, for example, the user leaves the room, the heating plate can be controlled to be closed, or if no human body exists in the room, the heating plate can be controlled to be closed, so as to save electric energy.
Preferably, the difference value between the distance and the preset distance threshold value is continuously detected to be larger than a second preset value within a first preset time, or the existence of a human body is not detected within the room for the first preset time, and the heating plate is controlled to be closed after continuously running for the second preset time. When the fact that the distance between the user and the heating plate is too far (namely the difference value between the distance between the user and the heating plate and the preset distance threshold value is larger than a second preset value) is continuously detected within a certain time, or the fact that the human body is not detected in a room where the user and the heating plate are continuously detected within the certain time, the heating plate is controlled to continuously operate for the second preset time and then is closed, and misjudgment can be avoided.
And S123, if the distance is smaller than the preset distance threshold, adjusting the heating power of the heating plate or controlling the heating plate to be closed according to the body surface temperature of the user.
Specifically, if the body surface temperature is lower than a second preset temperature value, the heating power of the heating plate is increased to a third heating power value; and/or if the body surface temperature is greater than or equal to a second preset temperature value, reducing the heating power of the heating plate to a preset power value or to a fourth heating power value; and/or controlling the heating plate to be closed if the body surface temperature is greater than or equal to a third preset temperature value.
More specifically, the second preset temperature value can be a body surface temperature value when the human body feels comfortable, and can be set according to actual conditions. If the body surface temperature of the user is smaller than the second preset temperature value, the heating requirement of the user is larger at the moment, and therefore the heating power of the heating plate can be improved, namely the heating power of the heating plate is improved or is improved to a third heating power value. If the body surface temperature of the user is larger than or equal to the second preset temperature value, the user is indicated to reach the comfort degree, the heating purpose is achieved at the moment, only the body temperature needs to be maintained, and the heating power of the heating plate can be properly reduced due to the fact that the air conditioner is also used for heating, namely the heating power of the heating plate is reduced to the preset power value or the fourth heating power value. When the body surface temperature of the user reaches a certain temperature, namely the third preset temperature value (the third preset temperature value is greater than the second preset temperature value), the body surface temperature of the user is higher at the moment, the user probably feels warmer, and the air conditioner can control the heating plate to be closed because the air conditioner heats, only heats through the air conditioner, and adjusts the current indoor environment temperature through the air conditioner.
Fig. 3 is a schematic flow chart of another embodiment of the step of adjusting the heating power of the heating plate or controlling the heating plate to be closed according to the distance between the user in the room and the heating plate and/or the body surface temperature of the user in the room. In another specific embodiment, as shown in fig. 3, step S120 includes step S124, step S125 and step S126.
Step S124, determining whether the body surface temperature of the user in the room is greater than or equal to a first preset temperature value.
Step S125, if the body surface temperature is lower than the first preset temperature value, the heating power of the heating plate is increased to a first heating power value.
Step S126, if the body surface temperature is larger than or equal to the first preset temperature value, reducing the heating power of the heating plate to a fifth heating power value or controlling the heating plate to be closed.
The first preset temperature value can be a body surface temperature value which is comfortable for human body feeling and can be set according to actual conditions. For example, in practical applications, when a user just enters a room from the outdoors, the sensible temperature of the human body is low, and at this time, the user wants to warm up the body as soon as possible, and after the user warms up for a period of time, along with the rise of the surface temperature of the human body, if the heating plate still maintains a high heating temperature, the surface temperature of the human body is too high and causes discomfort. Therefore, if the body surface temperature of the human body is lower than the first preset temperature value, the heating requirement of the user is larger at the moment, the heating plate needs to operate at higher power, and the heating power of the heating plate can be increased to the first heating power value at the moment. If the body surface temperature of the human body is larger than or equal to the first preset temperature value, the user is proved to have achieved the purpose of heating at the moment, and the heating plate can be controlled to be closed at the moment due to the fact that the air conditioner is in the heating mode, and energy is saved.
Preferably, when the body surface temperature is lower than the first preset temperature value, after the heating power of the heating plate is increased to the first heating power value for a preset time, whether the body surface temperature of the user in the room is greater than or equal to the first preset temperature value is judged again; if the body surface temperature is lower than the first preset temperature value, controlling the heating plate to continue to operate at the first heating power value, and if the body surface temperature is higher than or equal to the first preset temperature value, reducing the heating power of the heating plate to a fifth heating power value to control the heating plate to be closed.
For clearly explaining the technical solution of the present invention, the following describes an execution flow of the air conditioner control method provided by the present invention with a specific embodiment.
Fig. 4 is a schematic method diagram of an embodiment of an air conditioner control method according to the present invention. The embodiment shown in fig. 4 includes steps S201 to S206. In which a carbon crystal heating plate is taken as an example.
Step S201, after the air conditioner is turned on for heating, when the internal fan is not started (i.e., not rotated), the carbon crystal heating plate is controlled to be opened.
Step S202, after the inner fan starts to rotate, judging whether the distance between a human body (user) in a room and the carbon crystal heating plate reaches a preset distance threshold value, if the distance between the human body and the heating plate is smaller than the preset distance threshold value, controlling the power of the carbon crystal heating plate according to the body surface temperature of the user, and executing step S203 or step S204; if the distance between the human body and the heating plate is greater than the preset distance threshold value, the power of the carbon crystal heating plate is controlled according to the distance between the human body and the heating plate, and step S205 or step S206 is executed.
In step S203, if the body surface temperature is lower than the preset temperature value, the carbon crystal heating plate operates at a higher heating power (third heating power).
And step S204, if the body surface temperature of the human body is higher than the preset temperature value, reducing the power of the carbon crystal heating plate or closing the carbon crystal heating plate.
In step S205, if the distance between the human body and the heating plate is slightly greater than the preset distance threshold (i.e., the difference between the distance and the preset distance threshold is greater than the first preset value), the heating power of the heating plate is appropriately increased (to the second heating power value, not exceeding the upper limit of the heating power).
In step S206, if the distance between the human body and the heating plate is greater than a preset distance threshold (i.e., the difference between the distance and the preset distance threshold is greater than a second preset value), and the time period exceeds the preset distance threshold, the carbon crystal heating plate is closed.
Fig. 5 is a schematic method diagram of another embodiment of the air conditioner control method according to the present invention. The embodiment shown in fig. 5 includes steps S301 to S307. In which a carbon crystal heating plate is taken as an example.
And S301, after the air conditioner is heated and started and before the internal fan is not started, controlling the heating plate to be opened.
Step S302, after the internal air blower is started, determining whether the body surface temperature of the human body (user) in the room reaches a preset temperature value (a first preset temperature value), if the body surface temperature is lower than the preset temperature value, executing step S303, and if the body surface temperature is higher than the preset temperature value, executing step S307.
In step S303, if the body surface temperature is lower than the preset temperature value, the carbon crystal heating plate operates at a higher heating power (first heating power value), and step S304 is executed after a preset time.
In step S304, after the carbon crystal heating plate operates at a higher heating power (first heating power value) for a preset time, it is determined again whether the body surface temperature of the user reaches a preset temperature value, if so, step S305 is executed, and if not, step S306 is executed.
In step S305, if the body surface temperature of the user reaches the preset temperature value, the heating plate power is reduced (to the fifth heating power value) or the heating plate is turned off.
Step S306, if the body surface temperature of the user does not reach the preset temperature value, the user continues to operate with higher heating power (the first heating power value).
In step S307, if the body surface temperature of the user is higher than the preset temperature value, the heating plate is closed.
The invention also provides an air conditioner control device. The control device can be particularly used for a hot air type air source heat pump air conditioner. For example, a floor-standing air-source heat pump air conditioner is preferable. The air conditioner is provided with the heating plate, namely, heating is realized by converting electric energy into heat energy. For example, a heating panel is provided outside a panel of the air conditioner. The heating plate may be detachable. Preferably, the heating plate is a carbon crystal heating plate. The carbon crystal heating plate generates molecular motion between internal carbon atoms and generates violent friction and impact to generate a large amount of heat energy, the conversion rate of electric energy and the heat energy is up to more than 98%, and the carbon crystal heating plate is combined with a floor type air source heat pump air conditioner, so that the problem of delay in heat supply of the conventional air source heat pump air conditioner can be effectively solved, and the instant heating is realized.
Fig. 6 is a schematic structural diagram of an embodiment of an air conditioning control device provided by the present invention. As shown in fig. 6, the air conditioning control device 100 includes a first control unit 110 and a second control unit 120.
The first control unit 110 is configured to control the heating plate to be opened after the air conditioner is heated and started and before the indoor fan is started.
Specifically, when the air conditioner is started in the heating mode, the temperature of the inner pipe of the indoor unit is low, and the inner fan cannot be started at the moment in order to prevent cold air from being blown out. Therefore, after the air conditioner is turned on for heating and the internal fan is not started, the first control unit 110 controls the heating plate to be opened to set the heating power for heating. Because the heating plate can realize instant heating, the user can quickly heat when the user has the demand of instant heating, for example, the user can immediately heat when entering the room from the cold outdoor.
The second control unit 120 is configured to adjust the heating power of the heating plate or control the heating plate to be turned off according to the distance between the user in the room and the heating plate and/or the body surface temperature of the user in the room after the indoor fan is started.
Specifically, when the indoor fan is started and starts to blow out hot air, the second control unit 120 obtains a distance between a user in a room and the heating plate and/or a body surface temperature of the user in the room, and adjusts the heating power of the heating plate or controls the heating plate to be turned off according to the distance between the user in the room and the heating plate and/or the body surface temperature of the user in the room.
For example, the distance from the heating plate to the user in the room and/or the body surface temperature of the user in the room can be collected by an infrared human body detection sensor arranged outside the air conditioner. For example, the distance of the user from the heating plate is calculated from the time difference between the emission of the infrared signal and the reception of the user (human body) reflection signal.
In a specific embodiment, the second control unit 120 adjusts the heating power of the heating plate or controls the heating plate to be closed according to the distance between the user in the room and the heating plate and/or the body surface temperature of the user in the room, including: judging whether the distance between the user in the room and the heating plate is larger than or equal to a preset distance threshold value or not; if the distance is larger than or equal to the preset distance threshold, adjusting the heating power of the heating plate or controlling the heating plate to be closed according to the difference value between the distance and the preset distance threshold; and/or if the distance is smaller than the preset distance threshold value, adjusting the heating power of the heating plate or controlling the heating plate to be closed according to the body surface temperature of the user.
The preset distance threshold value can be specifically a distance value between a human body which enables the human body to feel comfortable and the heating plate. Specifically, if the difference between the distance and the preset distance threshold is greater than a first preset value, the second control unit 120 increases the heating power of the heating plate to a second heating power value; if the difference between the distance and the preset distance threshold is greater than a second preset value or no human body is detected in the room, the second control unit 120 closes the heating plate. Wherein the first preset value is smaller than the second preset value.
More specifically, if the difference between the distance and the preset distance threshold is greater than the first preset value, which indicates that the user is far away from the heating plate, the heating power of the heating plate needs to be properly increased, and the heating power of the heating plate can be increased to a second heating power value (which does not exceed the upper limit value of the heating power), so as to compensate the temperature of the user, and make the user feel comfortable. If the difference value between the distance and the preset distance threshold is larger than a second preset value, it indicates that the distance between the user and the heating plate is too far and exceeds the effective heat radiation range of the heating plate, for example, the user leaves the room, the heating plate can be controlled to be closed, or if no human body exists in the room, the heating plate can be controlled to be closed, so as to save electric energy.
Preferably, the difference between the distance and the preset distance threshold is continuously detected to be greater than a second preset value within a first preset time, or the presence of a human body is not detected within the room for the first preset time, and the second control unit 120 controls the heating plate to continuously operate for the second preset time and then to be closed. When the fact that the distance between the user and the heating plate is too far (namely the difference value between the distance between the user and the heating plate and the preset distance threshold value is larger than a second preset value) is continuously detected within a certain time, or the fact that the human body is not detected in a room where the user and the heating plate are continuously detected within the certain time, the heating plate is controlled to continuously operate for the second preset time and then is closed, and misjudgment can be avoided.
If the body surface temperature is lower than a second preset temperature value, the second control unit 120 increases the heating power of the heating plate to a third heating power value; if the body surface temperature is greater than or equal to a second preset temperature value, the second control unit 120 reduces the heating power of the heating plate by a preset power value or to a fourth heating power value; and if the body surface temperature is greater than or equal to a third preset temperature value, controlling the heating plate to be closed.
The second preset temperature value can be a body surface temperature value which is comfortable for human body feeling and can be set according to actual conditions. If the body surface temperature of the user is smaller than the second preset temperature value, the heating requirement of the user is larger at the moment, and therefore the heating power of the heating plate can be improved, namely the heating power of the heating plate is improved or is improved to a third heating power value. If the body surface temperature of the user is larger than or equal to the second preset temperature value, the user is indicated to reach the comfort degree, the heating purpose is achieved at the moment, only the body temperature needs to be maintained, and the heating power of the heating plate can be properly reduced due to the fact that the air conditioner is also used for heating, namely the heating power of the heating plate is reduced to the preset power value or the fourth heating power value. When the body surface temperature of the user reaches a certain temperature, namely the third preset temperature value (the third preset temperature value is greater than the second preset temperature value), the body surface temperature of the user is higher at the moment, the user probably feels warmer, and the air conditioner can control the heating plate to be closed because the air conditioner heats, only heats through the air conditioner, and adjusts the current indoor environment temperature through the air conditioner.
In another embodiment, the second control unit 120 adjusts the heating power of the heating plate or controls the heating plate to be turned off according to the distance between the user in the room and the heating plate and/or the body surface temperature of the user in the room, including: judging whether the body surface temperature of the user in the room is greater than or equal to a first preset temperature value or not; if the body surface temperature is lower than the first preset temperature value, the heating power of the heating plate is increased to a first heating power value; and/or if the body surface temperature is larger than or equal to the first preset temperature value, reducing the heating power of the heating plate to a fifth heating power value or controlling the heating plate to be closed.
The first preset temperature value can be a body surface temperature value which is comfortable for human body feeling and can be set according to actual conditions. For example, in practical applications, when a user just enters a room from the outdoors, the sensible temperature of the human body is low, and at this time, the user wants to warm up the body as soon as possible, and after the user warms up for a period of time, along with the rise of the surface temperature of the human body, if the heating plate still maintains a high heating temperature, the surface temperature of the human body is too high and causes discomfort. Therefore, if the body surface temperature of the human body is lower than the first preset temperature value, the heating requirement of the user is larger at the moment, the heating plate needs to operate at higher power, and the heating power of the heating plate can be increased to the first heating power value at the moment. If the body surface temperature of the human body is larger than or equal to the first preset temperature value, the user is proved to have achieved the purpose of heating at the moment, and the heating plate can be controlled to be closed at the moment due to the fact that the air conditioner is in the heating mode, and energy is saved.
Preferably, when the body surface temperature is lower than the first preset temperature value, after the heating power of the heating plate is increased to the first heating power value for a preset time, whether the body surface temperature of the user in the room is greater than or equal to the first preset temperature value is judged again; if the body surface temperature is lower than the first preset temperature value, controlling the heating plate to continue to operate at the first heating power value, and if the body surface temperature is higher than or equal to the first preset temperature value, reducing the heating power of the heating plate to a fifth heating power value to control the heating plate to be closed.
