Detailed Description
It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict.
Furthermore, the following description, if any, of "first," "second," etc. is used for descriptive purposes only and not for purposes of indicating or implying relative importance or implicitly indicating the number of technical features indicated. Furthermore, the terms "comprises," "comprising," or any other variation 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 air sweeping control method, aiming at solving the problem of temperature stratification in the vertical direction in an air conditioning room caused by floating hot air and sinking cold air.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
With reference to fig. 1, an embodiment of the present invention provides an air conditioner air sweeping control method, including the following steps:
s10, acquiring the current operation mode of the air conditioner;
it is easy to understand that, in the heating mode, the air conditioner blows hot air, the hot air is in an ascending trend at the moment, in the cooling mode, the air conditioner blows cold air, the cold air is in a descending trend at the moment, the existing air sweeping mode of the vertical cabinet type air conditioner blows air conditioner air into a room uniformly, the hot air floats upwards gradually at the moment, and the cold air sinks gradually, so that the temperature stratification phenomenon is caused, and therefore, whether the air conditioner is in the cooling mode or the heating mode needs to be detected, and different treatment methods are adopted according to the principle of the air conditioner and the heating mode, so that the temperature stratification phenomenon in the vertical direction of the room can be solved.
S20, when the current operation mode is a refrigeration mode, controlling the air conditioner to have the air sweeping time above the horizontal direction longer than the air sweeping time below the horizontal direction;
it should be noted that, referring to fig. 2, the horizontal direction is shown as an air outlet direction parallel to the air conditioner installation plane, and the cabinet air conditioner air outlet is usually located at a position with a middle height of the room, so that the air outlet direction above the horizontal direction can be regarded as the upper half of the room, and the air outlet direction below the horizontal direction can be regarded as the lower half of the room.
And S30, when the current operation mode is a heating mode, controlling the air conditioner to have the air sweeping time below the horizontal direction longer than the air sweeping time above the horizontal direction.
It should be emphasized that the control principle in the heating mode is basically the same as that in the cooling mode, but since the lower half of the room is also lower in temperature than the upper half of the room in the heating mode, hot air needs to be blown mainly to the lower half, and therefore, the air sweeping time below the horizontal direction should be not less than the air sweeping time above the horizontal direction.
According to the air conditioner heating and cooling system, different air sweeping strategies are set in a targeted mode according to the difference of the air conditioner in the cooling and heating modes, cold air is blown mainly to the upper half part of a room in the cooling mode, hot air is blown mainly to the lower half part of the room in the heating mode, the temperature stratification phenomenon of the room in the vertical direction caused by the fact that the cold air descends due to the fact that the hot air rises is solved, and the technical effect of relieving the temperature stratification phenomenon of the air conditioner room in the vertical direction is achieved.
Referring to fig. 3, S21, when the current operation mode is the cooling mode, controlling to reduce an included angle between a horizontal direction and a lower limit direction corresponding to a wind sweeping angle range of upper and lower wind sweeping blades of the air conditioner to a first preset value, and adjusting an upper limit direction corresponding to the wind sweeping angle range of the upper and lower wind sweeping blades to a direction which is located above the horizontal direction and has a preset maximum value with the horizontal direction, wherein the upper and lower wind sweeping blades move at a constant speed;
it is easy to understand that, referring to fig. 2, the lower limit direction corresponding to the wind sweeping angle range of the upper and lower wind sweeping blades of the air conditioner is shown in the figure, in this embodiment, the maximum wind sweeping angle is adjusted to make the wind sweeping time of the upper half of the room not less than the wind sweeping time of the lower half of the room, for example, when the first preset value is half of the maximum value, the lower limit direction is close to the position where the first preset value in fig. 2 takes the middle value, at this time, the air conditioner performs wind sweeping between the upper limit direction and the middle value of the first preset value, and the time for the airflow in the cooling mode to sweep below the horizontal direction is close to half of the time for the airflow to sweep above the horizontal direction.
And S31, when the current operation mode is a heating mode, controlling to reduce an included angle between an upper limit direction corresponding to a wind sweeping angle range of upper and lower wind sweeping blades of the air conditioner and the horizontal direction to a second preset value, and simultaneously adjusting a lower limit direction corresponding to the wind sweeping angle range of the upper and lower wind sweeping blades to a direction which is positioned below the horizontal direction and has a preset maximum value with the horizontal direction, wherein the upper and lower wind sweeping blades move at a constant speed.
It should be noted that, in this embodiment, the second preset value is smaller than the maximum value because the maximum value of the included angle between the uppermost wind sweeping direction and the horizontal direction is reduced, and the included angle between the uppermost wind sweeping direction and the horizontal direction is not much different from the included angle between the lowermost wind sweeping direction and the horizontal direction.
This embodiment is through under refrigeration mode and heating mode, the wind mode of sweeping that the setting corresponds, the angle is swept in the adjustment, make under refrigeration mode, the time and the scope that cold air up-blown all are greater than down-blowing, and under heating mode, the time and the scope that hot-air down-blown all are greater than up-blowing, along with cold air sinks gradually, hot-air rises gradually, the temperature in the room on the vertical direction is more unified, the phenomenon of the air conditioner room vertical temperature layering that exists among the prior art has been solved, reached and alleviated the technical effect of air conditioner room vertical temperature layering phenomenon, user experience has been promoted.
Referring to fig. 4, before the step of detecting the current operation mode of the cabinet air conditioner, the air conditioner wind sweeping control method further includes:
s11, acquiring the temperature difference in the indoor vertical direction;
it is easy to understand that, in this embodiment, the vertical temperature stratification degree in the air-conditioned room is determined by detecting the temperature difference in the indoor vertical direction, so as to execute a corresponding air sweeping strategy, thereby avoiding a new temperature stratification phenomenon in the vertical direction due to too aggressive air sweeping strategies.
S12, adjusting the first preset value and the second preset value according to the temperature difference in the indoor vertical direction, wherein the temperature difference in the vertical direction is in negative correlation with the first preset value and the second preset value.
It is worth emphasizing that, in the embodiment, the first preset value and the second preset value are adjusted by detecting the temperature difference in the indoor vertical direction, so that when the temperature difference is large, the first preset value and the second preset value are smaller, the problem of temperature stratification is solved more quickly, and when the temperature difference is small, the first preset value and the second preset value are larger, so that the situation that the cold air cannot sink in time due to too much cold air in the upper half part of the room is avoided; or the hot air at the lower half part of the room is too much, and the hot air cannot float upwards in time to cause a new layering phenomenon; for example, in the cooling mode, the first preset value and the second preset value when the temperature of the bottom of the room is 5 degrees lower than the temperature of the top of the room are smaller than the first preset value and the second preset value when the temperature of the bottom of the room is 2 degrees lower than the temperature of the top of the room.
Specifically, referring to fig. 5, the adjusting the first preset value and the second preset value according to the temperature difference in the vertical direction specifically includes:
s13, when the temperature difference in the vertical direction is smaller than the lower limit value of a first preset range, taking the included angle between the horizontal direction and the lower limit direction corresponding to the upper and lower wind sweeping angle ranges as the first preset value, and taking the included angle between the horizontal direction and the upper limit direction corresponding to the upper and lower wind sweeping angle ranges as the second preset value;
it should be noted that, in this embodiment, the first preset range is 3 ℃ to 5 ℃ (including 3 ℃ and 5 ℃), and therefore, when the temperature difference in the vertical direction is less than 3 ℃, it is not obvious that the temperature stratification phenomenon is determined only by a conventional wind sweeping mode, and therefore the maximum value of the first preset value and the second preset value is the included angle between the lower limit direction and the upper limit direction and the horizontal direction, so as to avoid new temperature stratification caused by uneven temperature of newly added air in the upper and lower parts of the room.
S14, when the temperature difference in the vertical direction is within a first preset range, taking half of an included angle between a lower limit direction and the horizontal direction corresponding to the upper and lower wind sweeping angle ranges as the first preset value, and taking half of an included angle between an upper limit direction and the horizontal direction corresponding to the upper and lower wind sweeping angle ranges as the second preset value;
it should be emphasized that, in this embodiment, when the temperature difference in the vertical direction is within the first preset range of 3 ℃ to 5 ℃ (including 3 ℃ and 5 ℃), it indicates that the temperature of the lower half of the room is 3 ℃ to 5 ℃ (including 3 ℃ and 5 ℃) lower than that of the upper half, and the temperature stratification phenomenon of the room can already feel that the temperature of the lower half of the room is lower than that of the upper half, and the first preset value and the second preset value need to be reduced to respective intermediate values, i.e., half of the included angles between the lower limit direction and the upper limit direction and the horizontal direction, referring to fig. 2, in this embodiment, the intermediate value is close to half of the maximum value, and at this time, the newly-cooled air of the upper half of the room is twice as large as that of the lower half, or the hot air of the lower half of the room is twice as that of the upper half, so as to solve the temperature stratification problem in the vertical direction of the room.
S15, when the temperature difference in the vertical direction is larger than the upper limit value of a first preset range and smaller than the lower limit value of a second preset range, taking 0 as the first preset value and the second preset value;
it is easy to understand that, in this embodiment, the second preset range is greater than or equal to 7 ℃, then when the room temperature is 5 ℃ to 7 ℃, the first preset value and the second preset value are 0, at this time, in the cooling mode, the air conditioner blows on only the upper half of the room, in the heating mode, the air conditioner blows on only the lower half, that is, in the cooling mode, cold air is delivered to a place with high temperature, in the heating mode, hot air is delivered to a place with low temperature, but as the cold air sinks and the hot air floats upwards, the cold air and the hot air still flow in the horizontal direction, so as to solve the problem of temperature stratification in the vertical direction of the room.
And S16, when the temperature difference in the vertical direction is in a second preset range, taking a negative value of half of an included angle between an upper limit direction and the horizontal direction corresponding to the upper and lower wind sweeping angle ranges as the first preset value, and taking a negative value of half of an included angle between a lower limit direction and the horizontal direction corresponding to the upper and lower wind sweeping angle ranges as the second preset value.
It is easy to understand that, in this embodiment, when the temperature difference is greater than or equal to 7 ℃, the user can feel discomfort obviously, and when the first preset value and the second preset value take a negative intermediate value, even if the cold air is calculated to be sunk, the cold air is still conveyed to the upper half part of the room completely, and also even if the hot air is calculated to be floated, the hot air is conveyed to the lower half part of the room completely, so as to solve the problem of temperature stratification in the vertical direction of the room in the extreme case.
According to the air-conditioning room temperature stratification state detection method, the air sweeping strategies of different degrees are adopted, the problem of temperature stratification in the vertical direction of the air-conditioning room is solved rapidly, the new stratification phenomenon that cold air is upward and hot air is downward due to too aggressive strategies is avoided, the temperature difference in the vertical direction of the air-conditioning room is adjusted to be within a proper range, the technical effect of improving the temperature stratification phenomenon in the air-conditioning room is achieved, and user experience is improved.
Referring to fig. 6, the air conditioner wind sweeping control method further includes:
and S17, when the air conditioner cannot acquire the temperature difference in the indoor vertical direction, the first preset value and the second preset value are 0.
It is easy to understand that most of the traditional vertical cabinet air conditioners are designed and manufactured, and no additional temperature sensor is designed to detect the temperature difference in the vertical direction of the room, so that the first preset value and the second preset value are set to be 0 when the vertical cabinet air conditioners face the products, the temperature stratification phenomenon in the air-conditioned room in the prior art can be solved under the hardware limitation of the existing air conditioner, and the application scenes of the vertical cabinet air conditioners are expanded.
In the embodiment, the first preset value and the second preset value are set to be 0 when the temperature difference in the indoor vertical direction cannot be detected, so that the temperature stratification phenomenon in the air-conditioned room can be solved for the vertical cabinet type air conditioner which cannot detect the indoor temperature difference, the application range of the invention is greatly expanded, and the technical effect of improving the temperature stratification phenomenon in the air-conditioned room is achieved.
Specifically, the controlling that the wind sweeping time of the air conditioner in the horizontal direction is longer than the wind sweeping time in the horizontal direction includes:
and controlling the swing speed of the upper and lower wind sweeping blades of the air conditioner in the horizontal direction to be smaller than the swing speed in the horizontal direction, and controlling the wind sweeping angle range of the upper and lower wind sweeping blades in the horizontal direction to be larger than or equal to the wind sweeping angle range in the horizontal direction.
It should be noted that, knowing that the wind sweeping time is equal to the wind sweeping angle divided by the swing speed of the upper and lower wind sweeping blades, the wind sweeping time can be adjusted by adjusting the wind sweeping angle when the air conditioner sweeps the wind at a constant speed, and the wind sweeping time can also be adjusted by adjusting the swing speed of the upper and lower wind sweeping blades.
The controlling the air conditioner to have the wind sweeping time below the horizontal direction longer than the wind sweeping time above the horizontal direction comprises:
and controlling the swing speed of the upper and lower wind sweeping blades of the air conditioner below the horizontal direction to be smaller than the swing speed above the horizontal direction, and controlling the wind sweeping angle range of the upper and lower wind sweeping blades below the horizontal direction to be larger than or equal to the wind sweeping angle range above the horizontal direction.
It is worth emphasizing that theoretically, under the condition that the wind sweeping angle below the horizontal direction is larger than the wind sweeping angle above the horizontal direction, the swing speed of the upper and lower wind sweeping blades below the horizontal direction is smaller than the swing speed of the upper and lower wind sweeping blades above the horizontal direction, the wind sweeping time below the horizontal direction can still be longer than the wind sweeping time above the horizontal direction by adjusting the swing speed and the wind sweeping angle of the upper and lower wind sweeping blades, but the application scenario is slightly limited, but the problem of temperature stratification in the vertical direction can still be solved when the upper and lower wind sweeping blades are fixed within a certain wind sweeping range; for example, if the range of the wind sweeping angle below the horizontal direction is only half of the range of the wind sweeping angle above the horizontal direction, but the swing speed of the upper and lower wind sweeping blades below the horizontal direction is only one third of the swing speed of the upper and lower wind sweeping blades above the horizontal direction, the wind sweeping time below the horizontal direction can be longer than the wind sweeping time above the horizontal direction; it will be readily appreciated that this solution also exists in the cooling mode.
In this embodiment, the technical effect of adjusting the air sweeping time is achieved by adjusting the swing speed of the upper and lower air sweeping blades, the problem of temperature stratification in the vertical direction in an air conditioning room in the prior art can be solved, the air sweeping blade is applied to the condition that the air sweeping blade is not beneficial to adjusting the air sweeping angle, the application scene of the technical scheme of the embodiment can be expanded, the condition that a user wants to blow cold air and cannot blow a client after the air sweeping angle is adjusted is avoided, and the user experience is improved.
The invention also provides an air conditioner air sweeping control device, which comprises:
the acquisition module acquires the current operation mode of the air conditioner;
the control module is used for controlling the air conditioner to be in a wind sweeping time above the horizontal direction to be longer than a wind sweeping time below the horizontal direction when the current operation mode is the refrigeration mode;
and when the current operation mode is a heating mode, controlling the air-conditioning to have the air sweeping time below the horizontal direction longer than the air sweeping time above the horizontal direction.
According to the embodiment of the invention, the operation mode of the vertical cabinet type air conditioner is detected by the acquisition module, and the air sweeping strategy under the refrigeration scene is adjusted by the control module, so that the phenomenon of temperature stratification in the air-conditioned room is solved, and the technical effect of improving the phenomenon of temperature stratification in the air-conditioned room is achieved.
Another embodiment of the present invention also provides an air conditioner, including: the air conditioner air sweeping control method comprises a computer readable storage medium and a processor, wherein a computer program is stored in the computer readable storage medium, and when the computer program is read and executed by the processor, the air conditioner air sweeping control method is realized.
