Detailed Description
It should be understood that the detailed description and specific examples, while indicating the invention, are intended for purposes of illustration only and are not intended to limit the scope of the invention.
As shown in fig. 1, fig. 1 is a schematic terminal structure diagram of a hardware operating environment according to an embodiment of the present invention.
The execution main body of the embodiment of the invention can be an air conditioner. The air conditioner may be a wall-mounted air conditioner.
As shown in fig. 1, the air conditioner may include: a processor 1001, such as a CPU, a communication bus 1002, and a memory 1003. The communication bus 1002 is used for realizing connection communication among the components. The memory 1003 may be a high-speed RAM memory or a non-volatile memory (e.g., a magnetic disk memory). The memory 1003 may alternatively be a storage device separate from the processor 1001.
Those skilled in the art will appreciate that the configuration of the air conditioner shown in fig. 1 is not intended to be limiting, and may include more or fewer components than those shown, or some components may be combined, or a different arrangement of components.
As shown in fig. 1, the memory 1003, which is a kind of computer storage medium, may include an operating system and a heating control program of an air conditioner.
Based on the structure of the air conditioner, a first embodiment of the present invention is proposed, and referring to fig. 2, fig. 2 is a schematic flow chart of the first embodiment of the heating control method of the air conditioner of the present invention, and the heating control method of the air conditioner includes the following steps:
step S100, after the air conditioner runs in a heating mode, acquiring the temperature of an indoor heat exchanger coil of the air conditioner;
and S200, controlling an air deflector of the air conditioner to deflect upwards when the temperature of the coil of the indoor heat exchanger is lower than a first preset temperature.
In the prior art, when the air conditioner operates in a heating mode and starts, cold air blown out from the air outlet blows towards a user due to the fact that the temperature of the indoor heat exchanger coil is low, and adverse effects can be caused on the body and experience of the user.
The indoor heat exchanger coil temperature refers to the temperature of the tube wall of the indoor heat exchanger of the air conditioner. A temperature sensor may be provided on the indoor heat exchanger coil to detect the temperature of the indoor heat exchanger coil.
The temperature of the coil of the indoor heat exchanger is related to the refrigerating capacity of the air conditioner, the exhaust temperature of the compressor, the indoor environment temperature, the outdoor environment temperature and the rotating speed of the indoor and outdoor fans, air enters the air conditioner through the air inlet to exchange heat with the indoor heat exchanger, the temperature of the air is further reduced, and cold air is sent out from the air outlet. Because the air-out temperature is low, the rotational speed of the indoor fan is also low, the air deflector deflects upwards, make the wind of the air outlet blow upwards, can make the air-out sent to the return air area of the air conditioner, make air-out and air conditioner return air form the short circuit, can the air conditioning system of fast stabilization.
As an alternative implementation, step S100 includes:
after the air conditioner runs in a heating mode, acquiring the temperature of an indoor heat exchanger of the air conditioner;
and when the temperature of the indoor heat exchanger of the air conditioner reaches the high-temperature protection temperature, and after a compressor of the air conditioner is closed, acquiring the temperature of an indoor heat exchanger coil of the air conditioner.
A temperature sensor can be arranged on the indoor heat exchanger to detect the temperature of the indoor heat exchanger. When the temperature of the indoor heat exchanger is higher than the high-temperature protection temperature, the compressor is turned off to stop heating in order to prevent the air conditioner from being burnt out, but the outdoor temperature is low, heat dissipation is easy, the temperature of the coil pipe of the indoor heat exchanger is easily reduced quickly, and the air outlet is enabled to blow out cold air. Even if the compressor is restarted, heating needs a period of time, and a condition that cold air is blown out from the air outlet also exists, so that the angle of the air deflector is adjusted by detecting the temperature of the coil pipe of the indoor heat exchanger at regular time, and the cold air at the air outlet can be effectively prevented from blowing to a user.
Optionally, when the air conditioner starts the heating function of the compressor, the indoor fan may not be started in a short time, but the indoor fan needs to be started in consideration of gradual temperature rise of the indoor heat exchanger and user experience, but in this time, due to heating in a short time, the temperature of the coil of the indoor heat exchanger is low, and the blown air is still cold air.
The first preset temperature can be set and adjusted by a designer according to the power and type of the air conditioner, and can also be related to the heating temperature set by a user.
The air conditioner may sense the indoor heat exchanger coil temperature via a temperature sensor, either periodically or at regular intervals, such as 30 seconds. And when the temperature of the coil pipe of the indoor heat exchanger is lower than a first preset temperature, controlling an air deflector of the air conditioner to deflect upwards.
The air deflector is controlled to deflect upwards. Alternatively, the control air deflector is deflected upwards by a certain angle, such as 30 degrees, counterclockwise from the preset position. Optionally, the air deflector is controlled to deflect upwards from the preset position, or the air deflector can deflect upwards from the preset position to a maximum angle, so that the air supply area of the air outlet is enabled to be minimum.
Optionally, the air deflector is rotatably disposed at the air outlet to open or close the air outlet. Alternatively, the air deflection plate may be an arcuate air deflection plate, wherein the arcuate air deflection plate may be outwardly convex.
When the air deflector deflects upwards, the upward inclination angle is larger, so that the air outlet of the air outlet circulates along the arc-shaped outer surface of the air deflector, and a relatively smaller air supply area is provided.
As an optional implementation manner, the heating control method of the air conditioner further includes:
and when the air conditioner exits the heating mode of the air conditioner, the air deflector is rotated to the preset position.
When the air conditioner is detected to exit from the heating mode of the air conditioner, the air deflector is moved to the preset position, and the position of the air deflector is reset, so that the normal heat dissipation of the air conditioner is facilitated, the stress of the supporting air deflector is reduced, and the service life of the air conditioner is prolonged. The air deflector is moved to a preset position, and can be directly operated and used in the next operation without adjustment.
In this embodiment, when being in the mode of heating through detecting the air conditioner, acquire the indoor heat exchanger coil temperature of air conditioner, when indoor heat exchanger coil temperature is less than first preset temperature, the control aviation baffle upwards deflects, when the air-out temperature is lower, blow on the wind direction of control air outlet, the position at user place is avoided to the wind that makes the air outlet, and then avoid directly blowing cold wind to the user when the air-out temperature is lower, blow cold wind upwards to be favorable to the air backward flow simultaneously, make air-out and air conditioner return air form the short circuit, realize the beneficial effect of rapid stabilization air conditioning system.
Based on the first embodiment, referring to fig. 3, fig. 3 is a schematic flow chart of a second embodiment of the heating control method of the air conditioner of the present invention, and after step S100, the method further includes:
and S300, when the temperature of the indoor heat exchanger coil is greater than or equal to the first preset temperature, adjusting the deflection direction of the air deflector according to the temperature of the indoor heat exchanger coil.
After the compressor is heated for a long time, the temperature of the indoor heat exchanger is gradually increased, and when the temperature of the coil pipe of the indoor heat exchanger is detected to be greater than or equal to a first preset temperature, the deflection direction of the air deflector can be adjusted according to the temperature of the coil pipe of the indoor heat exchanger.
In the heating operation process of the air conditioner, the air at the air outlet gradually becomes hot air, and the air with high temperature is easy to deviate to the upper layer of a room due to the thermal expansion effect and the hot air density is low, so that the heat exchange of the whole room is not facilitated, and the heat loss is caused.
Optionally, when the temperature of the indoor heat exchanger coil rises to a certain temperature, the air deflector can be deflected downwards from the current position, so that the air at the air outlet is blown to the wall, the air at the air outlet is blown to the ground along the wall, the heat exchange of the whole room from bottom to top is promoted, and the temperature of the whole room is increased.
Optionally, when the temperature of the coil of the indoor heat exchanger is further increased, the indoor environment temperature is greatly increased, and the air deflector can be deflected to the preset position from the current position, so that the air supply area of the air outlet is increased.
Optionally, an infrared detection device may be disposed on the air conditioner, and when the temperature of the indoor heat exchanger coil is high, the position of the user is obtained according to the infrared detection device, and the deflection angle of the air deflector is adjusted according to the position of the user, so as to blow the hot air at the air outlet to the user.
As an alternative implementation, referring to fig. 4, step S300 includes:
step S310, when the temperature of the coil pipe of the indoor heat exchanger is greater than or equal to the first preset temperature and is less than a second preset temperature, controlling the air deflector to deflect downwards;
and S320, controlling the air deflector to be in a preset position when the temperature of the coil of the indoor heat exchanger is greater than or equal to the second preset temperature.
The second preset temperature can be set and adjusted by designers according to the power and the type of the air conditioner, and is greater than the first preset temperature.
When the temperature of the coil pipe of the indoor heat exchanger is greater than or equal to a first preset temperature and less than a second preset temperature, the air deflector is controlled to deflect downwards from the current position so as to enable the air at the air outlet to blow towards the wall. The wind at the air outlet reaches the ground along the wall, and can be considered as hot wind because the temperature of the wind at the air outlet is higher than the indoor environment temperature. Because the density of the hot air is relatively low and drifts from bottom to top, the hot air and the indoor air are promoted to fully exchange heat, and the indoor environment temperature is gradually increased from bottom to top.
Optionally, when the air deflector is an arc-shaped air deflector, and the air deflector deflects downwards, the air flow circulates along the arc-shaped outer surface of the air deflector when passing through the air deflector due to the fact that the angle of the air deflector which inclines downwards is large, and therefore the foot warming function is achieved.
As an optional implementation manner, during the downward deflection of the air deflector, the indoor fan is controlled to rotate at a minimum rotation speed, and when the downward deflection of the air deflector is finished, the rotation speed of the indoor fan is increased in a stepwise manner until the rotation speed reaches a preset rotation speed.
The preset rotating speed can be the maximum rotating speed of the indoor fan corresponding to the temperature of the indoor heat exchanger coil pipe which is greater than or equal to the first preset temperature and less than the second preset temperature. When the rotating speed of the indoor fan is the preset rotating speed, the heating capacity of the air conditioner can be matched with the rotating speed of the fan, and heat exchange between the indoor heat exchanger and air can be well realized, wherein the preset rotating speed is obtained through multiple tests by designers.
In the process that the aviation baffle deflects downwards, because the temperature of current indoor heat exchanger coil pipe temperature is lower relatively, still is higher than indoor environment temperature, nevertheless because have certain wind speed, can carry out the heat exchange with the air simultaneously, if the wind of air outlet directly blows to the user, can let the user feel cold, produces not good user experience. In the downward deflection process of the air deflector, the indoor fan rotates at the minimum rotating speed so as to reduce the air output of the air outlet and reduce the influence of the blown cold air on users.
When the air deflector deflects downwards, the rotating speed of the indoor fan is increased in a stepped mode, the rotating speed of the indoor fan can be increased according to a preset time interval, for example, every 1 minute, the rotating speed of the indoor fan is increased by 100 revolutions, the rotating speed of the indoor fan can also be increased according to a certain speed, for example, every 100 revolutions per minute, the rotating speed of the indoor fan can also be increased in a gradually increasing mode, for example, the rotating speed is increased by 50 revolutions at a first time interval, and the rotating speed is increased by 100 revolutions at a second time interval. Through the rotational speed of increase indoor fan, increase the air output of air outlet, make the hot-blast and indoor cold wind that the air outlet sent out carry out the heat exchange to improve indoor ambient temperature fast.
At the in-process that deflects downwards of aviation baffle, the control room fan moves according to minimum rotational speed to the cold wind that reduces the air outlet blows to the user, after the deflection is downwards ended, cascaded increase indoor fan's rotational speed improves the air supply capacity of air outlet, in order to promote indoor ambient temperature fast.
The preset position can be a default position of the air deflector when the air conditioner is in the heating mode, such as a larger air output. The default position of the air deflector can be a position defined by a system, or a position of the air deflector recorded by the air conditioner in the last heating mode, or a position adjusted according to the requirement of a user, or a position vertical to a horizontal plane.
When the temperature of the indoor heat exchanger coil is greater than or equal to the second preset temperature, the temperature of the indoor heat exchanger coil is higher, the air deflector can be controlled to move to the preset position from the current position, so that the requirement of directly blowing to a user is met, or the air deflector can convey large air quantity to the indoor space, and the indoor environment temperature is further improved.
Optionally, the air blowing direction of the air deflector can be adjusted to be a direction perpendicular to the ground, so that hot air at the air outlet is blown to the ground vertically, and the air blowing direction of the air deflector can also be adjusted to be blown to a user. Through the air outlet with hot-blast vertical blow to ground, can follow supreme promotion indoor ambient temperature down, warm up earlier in the promotion room and cold, and to the human body, the warm head cold of foot more accords with human needs, reaches better heat transfer, promotes the effect that the user used and experienced.
In this embodiment, through detecting when indoor heat exchanger coil pipe temperature is greater than or equal to first preset temperature, according to the direction of deflection of indoor heat exchanger coil pipe temperature adjustment aviation baffle, when indoor heat exchanger coil pipe temperature is lower, the adjustment aviation baffle deflects downwards, in order to avoid blowing the lower wind of temperature to the user, when indoor heat exchanger coil pipe temperature is higher, the control aviation baffle is in preset position, increase air supply volume, in order to promote indoor ambient temperature fast, and simultaneously, can make whole room carry out the beneficial effect of even heat exchange.
Based on the second embodiment, referring to fig. 5, fig. 5 is a schematic flow chart of a third embodiment of a heating control method of an air conditioner according to the present invention, and after step S300, the method further includes:
and S400, adjusting the rotating speed of the indoor fan according to the temperature of the indoor heat exchanger coil, wherein the temperature of the indoor heat exchanger coil is positively correlated with the rotating speed of the indoor fan.
Along with the continuous increase of the heating capacity of the compressor, the temperature of the indoor heat exchanger is also continuously increased, and the rotating speed of the indoor fan needs to be adjusted.
At the preliminary stage that the compressor heats, because the compressor is also in the process of progressively raising the frequency, the heating capacity is low, can not open indoor fan, nevertheless along with the rising of indoor heat exchanger coil pipe temperature and user's use experience, need control indoor fan and rotate according to lower speed, can make the wind energy that the air outlet sent send the return air region of air conditioner for the air-out forms the short circuit with the return air of air conditioner, fast and stable air conditioner system.
After the temperature of the indoor heat exchanger coil is higher than the first preset temperature, the rotating speed of the indoor fan can be adjusted according to the temperature of the indoor heat exchanger coil. The temperature of the indoor heat exchanger coil is higher, the rotating speed of the indoor fan is higher, but the rotating speed of the indoor fan is smaller than or equal to the maximum rotating speed, and the temperature of the indoor heat exchanger coil is positively correlated with the rotating speed of the indoor fan.
Based on that the higher the temperature of the coil pipe of the indoor heat exchanger is, the more heat can be exchanged, the rotating speed of the indoor fan can be increased, the air supply quantity entering the indoor heat exchanger of the air conditioner can be increased, and the heat exchange between air and the indoor heat exchanger is increased, so that the indoor environment temperature is quickly improved.
It can be understood that if the temperature of the coil of the indoor heat exchanger is low and corresponds to a high indoor fan rotating speed, the exhaust temperature of the compressor is transmitted to the indoor heat exchanger, and then the heat is taken away by the air, which is not beneficial to the stable temperature rise of the indoor heat exchanger.
Optionally, can divide different temperature intervals with indoor heat exchanger coil pipe temperature, and the different temperature intervals can correspond the rotational speed of different indoor fans, according to the rotational speed of the indoor fan that the temperature interval that indoor heat exchanger coil pipe temperature that detects at present located corresponds, the control indoor fan is according to the rotational speed operation that corresponds to in order to realize the matching between the heating capacity of compressor and the air supply volume, promotes indoor ambient temperature fast.
In this embodiment, through detecting after indoor heat exchanger coil temperature is greater than or equal to first preset temperature, according to the rotational speed of indoor heat exchanger coil temperature adjustment indoor fan, indoor heat exchanger coil temperature is higher, the rotational speed of indoor fan is big more, indoor heat exchanger coil temperature is big more highly, the heating capacity that the compressor is big more is shown to indoor heat exchanger coil temperature, the air supply volume of air conditioner indoor heat exchanger is got into in the rotational speed increase through increasing indoor fan, the heat exchange between increase air and the indoor heat exchanger, in order to make heating capacity and fan rotational speed phase-match, promote indoor ambient temperature's beneficial effect fast.
Based on the first embodiment, referring to fig. 6, fig. 6 is a schematic flow chart of a third embodiment of a heating control method of an air conditioner according to the present invention, and after step S100, the method further includes:
step S500, reducing the rotating speed of the indoor fan according to the temperature of the indoor heat exchanger coil;
or, in step S600, the indoor fan is turned off.
Step S500 and step S600 are parallel steps to each other, and there is no execution precedence relationship.
When the temperature of the coil pipe of the indoor heat exchanger is smaller than the first preset temperature, the heating capacity of the air conditioner is relatively low, in order to enable the heating capacity to be matched with the rotating speed of the indoor fan, the heat of the indoor heat exchanger is rapidly taken away by air entering the indoor heat exchanger of the air conditioner, the temperature of the indoor heat exchanger is rapidly increased, the indoor heat exchanger is enabled to be stably heated, the rotating speed of the indoor fan can be reduced, and the rotating speed of the indoor fan is larger than or equal to the minimum rotating speed of the indoor fan. Or the indoor fan is turned off to reduce the heat loss of the indoor heat exchanger.
Optionally, when the temperature of the coil pipe of the indoor heat exchanger is lower than a third preset temperature, the indoor fan is controlled to stop rotating, namely the current temperature of the coil pipe of the indoor heat exchanger is very low, and in order to quickly raise the temperature of the indoor heat exchanger, heat consumption caused by the fact that the air supply rate of the indoor fan is large is reduced, and the indoor fan is controlled to stop rotating. When the temperature of the coil pipe of the indoor heat exchanger is higher than or equal to the third preset temperature and lower than the first preset temperature, the indoor fan is controlled to operate at a lower rotating speed, so that the heat of the indoor heat exchanger is dispersed uniformly, and meanwhile, the user is prompted that the air conditioner is started, so that the beneficial effect of no fault exists.
In this embodiment, when being less than first predetermined temperature through detecting indoor heat exchanger coil pipe temperature, the fan stall in the control room is with lower rotational speed operation or control room fan to reduce and cause the heat dispersion because of indoor heat exchanger's air supply, be unfavorable for indoor heat exchanger's temperature to rise, with the beneficial effect of the temperature of promoting indoor heat exchanger fast.
In addition, an embodiment of the present invention further provides an air conditioner, where the air conditioner includes a processor, a memory, and a heating control program of the air conditioner that is stored on the memory and is executable on the processor, and when the heating control program of the air conditioner is executed by the processor, the contents of the above-described embodiment of the heating control method of the air conditioner are implemented.
