Description
Technical Field
The invention relates to the field of control of air conditioners, in particular to an air conditioner and a control method thereof.
Background
Some users are used to adjust the air outlet direction of the air conditioner to be directly blown to the users when the difference between the ambient temperature and the comfortable temperature of the human body is large, so that the overheating/supercooling feeling of the users can be quickly relieved, however, after the ambient temperature approaches to the comfortable temperature of the human body, the direct blowing of the air conditioner can cause the users to feel cold and is not beneficial to the physical health of the users.
In order to solve the technical problem, chinese patent application publication No. CN111520864A discloses a control method for an air conditioner, which adjusts the frequency of a compressor, the angle of an air deflector, and the operating gear of an indoor fan according to the difference between a preset temperature and an indoor temperature in a comfortable temperature adjustment mode, and when the difference is within a preset range (lower than the preset value), the frequency of the compressor is decreased, the gear of the indoor fan is decreased, and the angle of the air deflector is adjusted to be up/down to prevent the air outlet of the air conditioner from blowing directly to a user; and when the difference value is not within the preset range, adjusting the angle of the air deflector to be horizontal air outlet.
However, there are some users who do not want the air conditioner to blow itself directly no matter how much the difference between the ambient temperature and the comfortable temperature of the human body is. When the air conditioner operates in a comfortable temperature adjusting mode, the air outlet of the air conditioner can blow directly to a user as long as the difference value is not within the preset range, and therefore the use requirement of the user cannot be met.
Disclosure of Invention
One of the objects of the present invention is to provide a control method of an air conditioner that can better satisfy the user's use requirement with respect to the control of whether or not to blow a person.
In order to achieve the above object, in the control method of the air conditioner provided by the present invention, the air conditioner includes an air deflector, a fan and a compressor, the air deflector has a preset first air guiding range and a preset second air guiding range, the first air guiding range is a direct blowing angle range, and the second air guiding range is a direct blowing prevention angle range; the control method comprises the following steps: acquiring an indoor environment temperature, an air conditioner set temperature and a set air guide angle of an air guide plate, wherein the absolute value of the difference between the indoor environment temperature and the air conditioner set temperature is a first difference value; under the first condition that the set wind guide angle is in the first wind guide range, controlling the wind guide angle of the wind guide plate to switch between the first wind guide range and the second wind guide range according to the first difference; in a second case where the wind guide angle is set within the second wind guide range, the wind guide angle of the wind guide plate is kept within the second wind guide range.
As can be seen from the above, if the set air guide angle is within the angle range of the direct-blowing user during operation of the air conditioner of the embodiment, when the difference between the set temperature of the air conditioner and the indoor environment temperature is small, the air guide angle of the air guide plate is adjusted to be within the direct-blowing prevention angle range, so as to prevent cold air from directly blowing the user under the condition; if the set wind guide angle is within the direct blowing prevention angle range, the wind guide angle of the wind guide plate is kept within the second wind guide range, so that the air outlet of the air conditioner can not be directly blown to the user all the time, the selection of the user on whether the air outlet of the air conditioner is directly blown or not is respected, the use requirements of the user can be better met, and the control method disclosed by the invention is suitable for users with different requirements.
In the invention, the direct blowing angle range is the angle range of the air deflector under the condition that the air outlet of the air conditioner can be directly blown to the user, and the direct blowing prevention angle range is the angle range of the air deflector under the condition that the air outlet of the air conditioner can not be directly blown to the user.
Preferably, the operation frequency of the compressor and/or the operation gear of the fan are controlled according to the first difference; when the first difference value is smaller than a preset second temperature difference limit value, the compressor runs at a first frequency, the fan runs at a first gear, and in a first condition, the air guide angle of the air guide plate is adjusted to a second air guide range; when the first difference is larger than a preset second temperature difference limit value, the air deflector is kept in a first air guide range or a second air guide range where a set air guide angle is located, the fan operates at a gear higher than a first gear, the compressor operates at a frequency higher than a first frequency, under the condition that the first difference is the same, the operating gear of the fan under the first condition is smaller than or equal to the operating gear of the fan under the second condition, and/or the operating frequency of the compressor under the first condition is smaller than or equal to the operating frequency of the compressor under the second condition.
Therefore, on one hand, the air conditioner is favorable for preventing the air conditioner from directly blowing the user with excessive cold/heat and wind speed under the first condition, the user experience is favorably improved, and the risk of cold caused by the fact that the body temperature of the user rises/falls too fast is also favorably reduced; on the other hand, the air conditioner runs at a higher compression frequency and a higher fan gear under the second condition, so that the comfort of a user is not influenced, the regulation and improvement capacity of the air conditioner on the indoor environment temperature under the second condition is favorably improved, and the temperature of the indoor environment is favorably and quickly regulated and improved.
Naturally, correspondingly, the operation gear of the fan and the operation frequency of the compressor may also be set to be unrelated to the set wind guide angle, that is, the same logic is adopted to control the operation gear of the fan and the operation frequency of the compressor no matter whether the set wind guide angle is in the range of the direct blowing prevention angle.
The further scheme is that the running gears of the fan also comprise a second gear and a third gear, and the first gear, the second gear and the third gear are sequentially increased; under the first condition, the highest operation gear of the fan is less than or equal to the third gear.
In a further scheme, under the first condition, if the first difference value is larger than the second temperature difference limit value and smaller than the fourth temperature difference limit value, the fan is controlled to operate at a second gear; and if the first difference value is larger than the fourth temperature difference limit value, controlling the fan to operate at a third gear.
It is from top to bottom visible, with fan gear and the compressor frequency increase and decrease according to the ladder law under the first condition, be favorable to avoiding the wind-force and the temperature variation of air conditioner air-out too big, be favorable to guaranteeing the travelling comfort of user when receiving air conditioner air-out direct-blowing user.
In a second situation, if the first difference value is larger than a second temperature difference limit value and smaller than a third temperature difference limit value, controlling the fan to operate at a second gear, wherein the third temperature difference limit value is smaller than a fourth temperature difference limit value; if the first difference value is larger than the third temperature difference limit value, controlling the fan to operate at a third gear; or under the second condition, if the first difference value is greater than the second temperature difference limit value and less than a third temperature difference limit value, controlling the fan to operate at a second gear, wherein the third temperature difference limit value is less than a fourth temperature difference limit value; if the first difference value is larger than the third temperature difference limit value and smaller than the fifth temperature difference limit value, controlling the fan to operate at a third gear; and if the first difference value is larger than the fifth temperature difference limit value, controlling the fan to operate at a fourth gear, wherein the fourth gear is larger than the third gear.
In a further aspect, under a second condition, if the first difference is greater than the second temperature difference limit, the fan is controlled to operate at a third gear or the fan is controlled to operate at a fourth gear, and the fourth gear is greater than the third gear.
It can be seen from above that because the air conditioner air-out can not blow the user directly under the second condition, therefore directly adjust the operation gear of fan to the highest state when first difference is greater than second difference limit value to the temperature of quick adjustment and improvement indoor environment.
The running frequency of the compressor comprises a first frequency, a second frequency, a third frequency and a fourth frequency from low to high, and when the fan runs at a first gear, the compressor runs at the first frequency; when the fan operates at a second gear, the compressor operates at a second frequency; when the fan operates at a third gear, the compressor operates at a third frequency; and when the fan operates at a fourth gear, the compressor operates at a fourth frequency.
Therefore, the running frequency of the compressor is matched with the running gear of the fan, and the running frequency of the compressor is matched with the temperature regulation requirement.
The further scheme is that when the first difference value is smaller than a preset first temperature difference limit value, the compressor is controlled to enter a standby state, and the first temperature difference limit value is smaller than a second temperature difference limit value.
Therefore, the energy saving of the air conditioner is facilitated.
In another preferred embodiment, in the second case, the wind guiding angle of the wind guiding plate is kept to be the set wind guiding angle; and/or the air deflector comprises a first plate and a second plate, the first plate is rotatably arranged on the upper edge of the air outlet of the air conditioner, the second plate is rotatably arranged on the lower edge of the air outlet, the rotation axis of the first plate and the rotation axis of the second plate are in a first direction, the first direction is perpendicular to the penetrating direction of the air outlet, and the first direction is perpendicular to the spacing direction of the first plate and the second plate.
Therefore, the selection of the user on the wind guide angle is better respected; compared with the scheme that the air deflector is arranged on one side of the upper edge or the lower edge, the air guide device is beneficial to expanding the air guide range of the air outlet of the air conditioner in the vertical direction; the first plate and the second plate are rotatably connected to the edge of the air outlet, so that the air quantity cannot leak from the back of the air deflector, and the air quantity loss is reduced; in addition, the accuracy of adjusting and controlling the air guide direction is improved, and the control purpose is convenient to realize.
The invention also aims to provide an air conditioner which can better meet the use requirements of users by controlling whether to blow people or not.

The control method is exemplified by the condition that the air deflector is in four preset states, wherein in the first preset state, referring to fig. 1, the first plate 2 is raised by 2 degrees in the positive direction relative to the Y axis, and the second plate 3 is raised by 15 degrees in the positive direction relative to the Y axis; in a second preset condition, see fig. 2, the first plate 2 is tilted 5 ° downwards and the second plate 3 is tilted 9 ° downwards in relation to the Y axis; in a third predetermined condition, as shown in fig. 3, the first plate 2 is tilted downward 38 ° with respect to the Y-axis, and the second plate 3 is tilted downward 26 ° with respect to the Y-axis; in a fourth preset condition, referring to fig. 4, the first plate 2 is downwardly inclined 83 ° with respect to the Y-axis, and the second plate 3 is downwardly inclined 87 ° with respect to the Y-axis; the air deflector is in a first range in a first preset state, is in the first air guiding range in a second preset state and a third preset state, and is in a second range in a fourth preset state.
If the first step S101 detects that the air conditioner operates in the cooling mode and the air deflector is in the state (second air guiding range) shown in fig. 1, when the first difference is greater than 2 ℃, the fan operates at the highest fourth gear, and the compressor operates at the highest fourth frequency; when the first difference is less than or equal to 2 ℃, the fan operates at the lowest first gear, and the compressor operates at the lowest first frequency.
If the first step S101 detects that the air conditioner operates in the cooling mode and the air deflector is in the state (the first air guiding range) shown in fig. 2, when the first difference is greater than 5 ℃, the fan operates at a third gear and the compressor operates at a third frequency; when the first difference value is greater than 2 ℃ and less than or equal to 5 ℃, the fan operates at a second gear, and the compressor operates at a second frequency; when the first difference is less than or equal to 2 ℃, the fan operates at a first gear, the compressor operates at a first frequency, and the air deflector is adjusted to a first range.
If the first step S101 detects that the air conditioner operates in the heating mode and the air deflector is in the state (the first air guiding range) shown in fig. 3, when the first difference is greater than 5 ℃, the fan operates at a third gear and the compressor operates at a third frequency; when the first difference value is greater than 2 ℃ and less than or equal to 5 ℃, the fan operates at a second gear, and the compressor operates at a second frequency; when the first difference is less than or equal to 2 ℃, the fan operates at a first gear, the compressor operates at a first frequency, and the air deflector is adjusted to a second range.
If the first step S101 detects that the air conditioner operates in the heating mode and the air deflector is in the state (second air guiding range) shown in fig. 4, when the first difference is greater than 2 ℃, the fan operates at the highest fourth gear, and the compressor operates at the highest fourth frequency; when the first difference is less than or equal to 2 ℃, the fan operates at the lowest first gear, and the compressor operates at the lowest first frequency.
It should be noted that, whether the air deflector can blow directly to the user when operating at a specific angle is also related to the installation position and height of the indoor unit, so each angle relationship of the embodiment is only used for explaining the technical solution of the embodiment, and the first range, the second range and the first air guiding range of the air deflector can be set for specific situations; of course, the first range and the second range may be set in a conservative manner according to the type and model of the air conditioner, for example, in a wall-mounted unit, no matter how high the wall-mounted unit is installed, generally, as long as the air deflector is in the raising state, the situation of the air-out direct-blowing user of the air conditioner does not occur, and therefore, the raising angle range of the air deflector can be set as the first range.
Because the air outlet is adjusted when the set air guide angle is not at the first air guide angle (at the second air guide angle), the direct blowing cannot be caused to the user, and the body feeling of the user cannot be obviously influenced by the air outlet temperature/air speed at the time, the fan is adjusted to operate at the fourth gear of the highest gear when the first difference is more than 2 ℃, and the compressor is adjusted to operate at the fourth frequency of the highest frequency, so that the temperature of the indoor environment can be quickly adjusted and improved; moreover, in this embodiment, when the air guide angle is not set within the first air guide range, the highest operating gear (fourth gear) of the fan is higher, and the highest operating frequency (fourth frequency) of the compressor is higher, and when the air guide angle is set within the first air guide range, the highest operating gear (third gear) of the fan is lower, and the highest operating frequency (third frequency) of the compressor is lower, which is not only beneficial to avoiding discomfort to the user when the air-out of the air conditioner is blown directly to the user, but also beneficial to improving the regulation and improvement rate of the indoor environment temperature as much as possible when the air-out of the air conditioner is not blown directly to the user.
In the embodiment, the air guide angle of the air guide plate is not changed in the process of executing the step one S101 to the step six S106 and the step eight S108 to the step ten S110, and the air guide angle of the air guide plate is kept to be the set air guide angle in the process, which is favorable for better meeting the use requirements of users; of course, in another embodiment of the present invention, in each step described above in this paragraph, the air guiding angle of the air guiding plate may be adjusted within the first air guiding range and the second air guiding range in which the air guiding angle is set.
Of course, in other embodiments of the present invention, the air conditioner has only a single cooling (or heating) function, so that the above method does not need to obtain a cooling/heating mode, and the air conditioner can be controlled to operate in the cooling (or heating) mode uniformly.
