The embodiment of the present disclosure provides an air conditioner including a cabinet 100 and an indoor heat exchanger 110. As shown in fig. 1, the casing 100 is provided with an air outlet 101 and an air inlet 102, and the indoor heat exchanger 110 is disposed in the casing 100. When the air conditioner operates in the dehumidification mode, the indoor heat exchanger 110 is cooled. Air enters the casing 100 from the air inlet 102 and is condensed when passing through the indoor heat exchanger 110, so that the humidity of the air is reduced. Then, the low-temperature dried air is blown into the room from the air outlet 101, but at the same time, the temperature in the room is caused to be low.
In some embodiments, the air conditioner further includes a heating device 200. The heating device 200 includes a first heating part 210 and a second heating part 220. The first heating portion 210 is rotatably disposed on a first side of the air outlet 101, and the second heating portion 220 is rotatably disposed on a second side of the air outlet 101. The heating device 200 has a heating position corresponding to the airflow path through which the first heating portion 210 and/or the second heating portion 220 are rotated to the air outlet 101, and a retracted position corresponding to the airflow path through which the first heating portion 210 and the second heating portion 220 are retracted.
In the present embodiment, the heating device 200 is disposed at the air outlet 101, and when the first heating portion 210 and/or the second heating portion 220 are rotated to the heating position, the air blown out from the air outlet 101 can be heated. In this way, in the case of cooling and dehumidifying the air conditioner, the temperature of the low-temperature dried air is increased when the air passes through the heating device 200, and thus the outlet air temperature of the air conditioner is increased, thereby realizing the effect of constant temperature dehumidification. In addition, under the condition that the air conditioner does not need constant temperature dehumidification, the first heating part 210 and the second heating part 220 can rotate to the avoiding positions, and at this time, the heating device 200 does not influence the normal air outlet of the air conditioner.
Alternatively, as shown in fig. 2, the first heating part 210 includes a mounting plate 240 and a heating member 250. Wherein a first side of the mounting plate 240 is provided with a rotational axis 244. A heating member 250 is provided on the mounting plate 240 for heating air flowing therethrough. The second heating unit 220 has the same structure as the first heating unit 210.
In the present embodiment, in order to facilitate distinguishing between the first heating portion 210 and the second heating portion 220, the mounting plates 240 of the first heating portion 210 and the second heating portion 220 are referred to as a first mounting plate 241 and a second mounting plate 242, respectively, and the heating members 250 are referred to as a first heating member 251 and a second heating member 252, respectively. Wherein a second side of each mounting plate 240 may be flipped about a corresponding rotational axis 244.
Optionally, the length direction of the mounting plate 240 is parallel to the length direction of the air outlet 101. The first mounting plate 241 is located on a first side of the air outlet 101 in the width direction, for example, on an upper side of the air outlet 101. The second mounting plate 242 is located at a second side of the air outlet 101 in the width direction, for example, a lower side of the air outlet 101.
Alternatively, as shown in fig. 2, the heating member 250 includes a heating belt 253 and a heat sink 254. The heating belt 253 is connected to a heating power source, and the heating belt 253 generates heat when the heating power source is powered on. The heat radiating fins 254 are disposed on the heating belt 253 for radiating heat. Thus, when the heating power supply is energized, the heating belt 253 generates heat. And, heat is efficiently diffused to the air flowing therethrough by the heat sink 254.
Alternatively, the heating tape 253 is disposed along the length direction of the mounting plate 240, and a plurality of heat radiating fins 254 are symmetrically disposed at both sides of the heating tape 253. In this way, the longer heating belt 253 can be arranged, and the temperature diffusion of the heat radiating fins 254 is relatively uniform, thereby improving the heating effect of the heating member 250.
Optionally, as shown in fig. 2, the mounting plate 240 is provided with ventilation holes 243.
In this embodiment, when the heating device 200 is located at the heating position, the air outlet is blocked to a certain extent because the heating device is located on the air flow path of the air outlet 101. Here, by providing the vent holes 243 in the mounting plate 240, blocking can be reduced, and the air-out effect can be improved. Also, when the heating device 200 is in the evasive position, heat may be dissipated to the air flowing therethrough through the vent 243 when the heating element 250 is activated.
Alternatively, the diameter of the ventilation holes 243 is d, and 1 mm≤d≤2 mm. Thus, by setting a reasonable aperture, the air outlet is more smooth.
In some embodiments, as shown in fig. 4, the air conditioner further includes a through-flow air duct 300. The through-flow air duct 300 includes an air duct upper wall 310 and an air duct lower wall 320, and the end of the air duct upper wall 310 and the end of the air duct lower wall 320 define an air duct outlet, and the air duct outlet faces the air outlet 101. The air duct upper wall 310 has a first chamber 311 disposed at an end thereof, and the first chamber 311 is configured to house the first heating portion 210. The end of the air duct lower wall 320 is provided with a second chamber 321, and the second chamber 321 is used for accommodating the second heating part 220.
In this embodiment, the front end of the duct upper wall 310 and the front end of the duct lower wall 320 define the duct inlet. The cross-flow fan 120 is arranged in the cross-flow air duct 300, when the cross-flow fan 120 is started, air enters the cross-flow air duct 300 from the air duct inlet, then is blown to the air outlet 101 from the air duct outlet, and finally is blown into a room from the air outlet 101. By providing the first chamber 311 and the second chamber 321, the space inside the through-flow duct 300 is not occupied, and the first heating part 210 and the second heating part 220 can be provided with a space.
Optionally, as shown in fig. 5, the end of the duct upper wall 310 is provided with a front volute tongue 312. In the retracted position, the heating element 250 of the first heating portion 210 is positioned within the first compartment 311, the mounting plate 240 of the first heating portion 210 covers the first compartment 311, and a second side of the mounting plate 240 corresponds to the front volute tongue 312.
In the present embodiment, at the avoidance position, the first mounting plate 241 covers the first chamber 311, so that some foreign matters can be prevented from entering the first chamber 311. In the case where the second side of the first mounting plate 241 corresponds to the front volute tongue 312, the air flows out from the front volute tongue 312 and then continues to flow along the first mounting plate 241 toward the air outlet 101. In this way, the first mounting plate 241 can also function to direct the circulation of air. As shown in fig. 5, in the case where the first mounting plate 241 is provided with the ventilation holes 243, even if the first mounting plate 241 is located at the escape position, heat can be transferred from the ventilation holes 243 to the air flowing therethrough as long as the first heating member 251 starts heating. In this way, the air outlet temperature can be increased without blocking the air outlet.
Alternatively, as shown in fig. 7, the mounting plate 240 of the first heating portion 210 may be rotated from the dodging position toward the inside of the air outlet 101 to the heating position. The rotation angle of the mounting plate 240 is alpha, and alpha is more than or equal to 0 deg. and less than or equal to 53 deg..
In the present embodiment, the first mounting plate 241 is turned by an angle α of 0 ° at a position covering the first chamber 311 and corresponding to the front volute tongue 312, as shown in fig. 5. The first mounting plate 241 is rotated to the limit position toward the air outlet 101 by an angle of rotation α of 53 °, as shown in fig. 7.
Optionally, the first heating portion 210 further includes a first motor, and the first motor is configured to rotate the first mounting plate 241. The first motor is electrically connected to the heating controller, and the heating controller adjusts the rotation angle α of the first mounting plate 241 by the first motor.
Optionally, as shown in fig. 6, the end of the duct lower wall 320 is provided with an air outlet section 323. In the dodged position, the heating element 250 of the second heating portion 220 is located in the second chamber 321, the mounting plate 240 of the second heating portion 220 covers the second chamber 321, and the second side of the mounting plate 240 corresponds to the air outlet section 323.
In the present embodiment, at the avoidance position, the second mounting plate 242 covers the second chamber 321, so that some foreign matters can be prevented from entering the second chamber 321. When the second side of the second mounting plate 242 corresponds to the air outlet section 323, the air flows out of the air outlet section 323 and then continues to flow along the second mounting plate 242 toward the air outlet 101. In this way, the second mounting plate 242 can also function to direct the flow of air. As shown in fig. 6, in the case where the second mounting plate 242 is provided with the ventilation holes 243, even if the second mounting plate 242 is located at the escape position, heat can be transferred from the ventilation holes 243 to the air flowing therethrough as long as the second heating member 252 starts heating. In this way, the air outlet temperature can be increased without blocking the air outlet.
Alternatively, as shown in fig. 7, the mounting plate 240 of the second heating portion 220 may be rotated from the dodging position toward the inside of the air outlet 101 to the heating position. The rotation angle of the mounting plate 240 is beta, and beta is more than or equal to 0 deg. and less than or equal to 65 deg..
In the present embodiment, the second mounting plate 242 takes a rotation angle β of 0 ° at a position covering the second cabin 321 and corresponding to the air outlet section 323, as shown in fig. 6. The second mounting plate 242 rotates toward the air outlet 101 to a limit position, and the rotation angle β is 65 °, as shown in fig. 7.
Optionally, the second heating portion 220 further includes a second motor, and the second motor is configured to rotate the second mounting plate 242. The second motor is electrically connected to the heating controller, and the heating controller adjusts the rotation angle β of the second mounting plate 242 by the second motor.
Optionally, after the first mounting plate 241 and the second mounting plate 242 are respectively rotated to the extreme positions, a circulation gap is still provided therebetween. The rotation angle of the mounting plate 240 varies, and there is a difference in heating effect on the air flowing therethrough. Wherein, when α takes 53 ° and β takes 65 °, the air flowing therethrough can be sufficiently contacted with the first heating member 251 and the second heating member 252, and the heating effect is the best at this angle. And under the action of the circulation gap, the air outlet of the air conditioner is ensured.
In some embodiments, as shown in fig. 1, the air conditioner further includes an air deflector 260. The air deflector 260 is rotatably disposed at the air outlet 101. The heating device 200 further includes a third heating portion 230, where the third heating portion 230 is disposed on the air deflector 260. In this way, the air guide plate 260 guides the air in the air direction, and the third heating unit 230 can heat the air flowing therethrough. The first heating part 210, the second heating part 220 and the third heating part 230 are combined to use, and the constant temperature dehumidification effect is further improved.
Alternatively, as shown in fig. 3, the third heating part 230 is embedded in the air deflector 260, and the third heating part 230 includes an embedded heating belt 261 and an embedded heat sink 262. Wherein, embedded heating band 261 connects in heating power, and embedded heating band 261 produces the heat when heating power circular telegram. The embedded heat sink 262 is disposed on the embedded heating belt 261 for dissipating heat.
In this embodiment, since the wind deflector 260 mainly plays a role in guiding wind direction, the third heating part 230 is mounted in an embedded manner in order to secure the wind guiding effect. Thus, when the heating power source is energized, the embedded heating belt 261 generates heat. And, the heat is diffused to the plate body of the air guide plate 260 by the embedded heat sink 262, thereby heating the air flowing through the air guide plate 260.
Alternatively, the embedded heating belt 261 is arranged along the length direction of the air guide plate 260, and the embedded heat radiating fins 262 are arranged along the width direction of the air guide plate 260.
Optionally, the third heating portion 230 further includes a third motor, and the third motor is used to drive the air deflector 260 to rotate. The third motor is electrically connected to the heating controller, and the heating controller adjusts the rotation angle of the air deflector 260 by the third motor.
The embodiment of the disclosure also provides a method for controlling the air conditioner, and the structure of the air conditioner is detailed above. As shown in fig. 9, the method includes:
S10, the heating controller acquires the temperature difference between the set temperature and the indoor temperature and acquires the indoor relative humidity;
And S20, controlling the operation states of the first heating part and the second heating part by the heating controller according to the temperature difference and the relative humidity.
In this embodiment, when the air conditioner is cooled and dehumidified, the indoor temperature is generally lower than the user's set temperature, resulting in discomfort to the user. In this embodiment, the heating device is disposed at the air outlet, and the first heating portion and the second heating portion can heat the air blown out from the air outlet. In this way, the temperature of the dehumidified low-temperature dried air increases when it passes through the heating device, and thus the indoor temperature increases. Therefore, the operation states of the first heating portion and the second heating portion are controlled according to the temperature difference and the relative humidity, and the constant-temperature dehumidification effect can be achieved. Here, the indoor temperature is denoted by T0, the set temperature is denoted by T1, and the temperature difference between the set temperature and the indoor temperature is denoted by T, and t1—t0=t.
Optionally, in step S20, the heating controller controls the operation states of the first heating part and the second heating part according to the temperature difference and the relative humidity, including:
the heating controller controls the rotation angle of the first mounting plate and the second mounting plate according to the temperature difference and the relative humidity, and controls the opening or closing of the first heating element and the second heating element.
In this embodiment, in the case where the first heating member and the second heating member are turned on, the air flowing therethrough can be heated. In the case where the first heating member and the second heating member are turned off, the air cannot be heated. And, the rotation angle of first mounting panel and second mounting panel is different, and the heating effect of convection air is different.
Alternatively, as shown in FIG. 10, the steps of the heating controller controlling the rotation angles of the first and second mounting plates and the opening or closing of the first and second heating members according to the temperature difference and the relative humidity include:
s21, when the relative humidity is greater than or equal to a first humidity threshold value, and the temperature difference is greater than zero and smaller than a first temperature threshold value, the heating controller controls the first mounting plate and the second mounting plate not to rotate, and the heating controller controls the first heating piece and the second heating piece to start;
S22, when the relative humidity is greater than or equal to a first humidity threshold value and the temperature difference is greater than or equal to a first temperature threshold value, the heating controller controls the first mounting plate and the second mounting plate to rotate from the first cabin and the second cabin towards the air outlet respectively, and the heating controller controls the first heating element and the second heating element to start;
S23, when the relative humidity is smaller than a second humidity threshold and the indoor temperature is larger than or equal to the set temperature, the heating controller controls the first mounting plate and the second mounting plate to rotate back to the first cabin and the second cabin respectively, and the heating controller controls the first heating piece and the second heating piece to stop, wherein the second humidity threshold is smaller than the first temperature threshold.
In the present embodiment, in the case where the relative humidity is greater than or equal to the first humidity threshold, the humidity is large and dehumidification is required.
Wherein, in case the temperature difference is greater than zero and less than the first temperature threshold, the temperature difference is relatively small. At this time, the first mounting plate and the second mounting plate do not rotate, but the first heating member and the second heating member are activated. Under the action of the vent holes, the first heating element and the second heating element can heat the air flowing through even if the first heating element and the second heating element are respectively positioned in the first cabin and the second cabin. In this way, the air outlet temperature can be increased without blocking the air outlet.
Wherein, in the case that the temperature difference is greater than or equal to the first temperature threshold, the temperature difference is relatively large. At this time, the first mounting plate and the second mounting plate are rotated toward the air outlet, and the first heating member and the second heating member are started. Thus, when the air flows through the first heating element and the second heating element, the air can be efficiently heated, and the indoor temperature is rapidly increased.
When the relative humidity is smaller than the second humidity threshold value and the indoor temperature is larger than or equal to the set temperature, the humidity and the temperature meet the temperature requirement of a user, and a more comfortable body feeling is brought. At this time, the first heating member and the second heating member are rotated back into the first chamber and the second chamber, respectively. Thus, the blocking of the normal air outlet of the air conditioner can be avoided.
Alternatively, the first humidity threshold is 70% rh and the second humidity threshold is 50% rh
Optionally, when the air conditioner is switched from the heating mode to the constant temperature dehumidification mode, the first temperature threshold value is 0.5 ℃.
Optionally, when the air conditioner is switched from the cooling mode to the constant temperature dehumidification mode, the first temperature threshold value is 1 ℃.
Alternatively, the larger the temperature difference, the larger the rotation angle of the first and second mounting plates. As shown in FIG. 7, the first mounting plate has a rotation angle α, and 0≤α≤53°. The rotation angle of the second mounting plate is beta, and beta is more than or equal to 0 degree and less than or equal to 65 degrees.
In this embodiment, the rotation angles of the mounting plates are different, and there is a difference in the heating effect on the air flowing therethrough. Under the condition of larger temperature difference, larger rotation angle is needed, so that air flowing through can be fully contacted with the first heating piece and the second heating piece, and the air outlet temperature is further rapidly increased. Because the space at the air outlet is limited, the first mounting plate, the second mounting plate and the air deflector can be prevented from interfering with each other by limiting the range of alpha and beta.
Alternatively, in the case where the temperature difference is greater than the first temperature threshold, α increases by 10 ° and rotates up to 53 ° for every 1 ° increase in the temperature difference. Meanwhile, every 1 ℃ is increased in temperature difference, beta is increased by 10 degrees, and the maximum rotation is 65 degrees.
Alternatively, the air deflector has a first position corresponding to the air deflector being rotated to be positioned in the middle of the air outlet, as shown in fig. 7. When the air deflector rotates to the first position, the vent hole of the first mounting plate is opposite to the air deflector in the range of values of alpha and beta, and the vent hole of the second mounting plate is opposite to the air deflector. And, the air flowing through the first mounting plate can be blown to the air guide plate through the vent hole, and the air flowing through the second mounting plate can be blown to the air guide plate through the vent hole. Thus, after the air is heated by the first heating part and the second heating part, the air can be heated by the third heating part, and the heating effect of the third heating part is ensured.
Alternatively, in steps S21 and S22, the air deflector may be rotated to the first position, and the third heating part is simultaneously activated.
As shown in fig. 11, the embodiment of the present disclosure further provides another method for controlling an air conditioner, including:
S10, the heating controller acquires the temperature difference between the set temperature and the indoor temperature and acquires the indoor relative humidity;
And S20, controlling the operation states of the first heating part and the second heating part by the heating controller according to the temperature difference and the relative humidity.
And S30, controlling the rotation angle of the air deflector by the heating controller according to the temperature difference and the relative humidity.
Optionally, as shown in fig. 12, in step S30, the heating controller controls the rotation angle of the air guide plate according to the temperature difference and the relative humidity, including:
And S31, when the relative humidity is greater than or equal to a first humidity threshold and the temperature difference is greater than or equal to a second temperature threshold, the heating controller controls the air deflector to rotate to be abutted against the first mounting plate, wherein the second temperature threshold is greater than the first temperature threshold.
And S32, controlling the third heating part to start by the heating controller under the condition that the temperature rising rate of the indoor temperature is smaller than the preset rate.
In this embodiment, the air deflector has a second position corresponding to the air deflector being rotated to abut the first mounting plate, as shown in fig. 8. In step S31, the air deflector rotates to the second position, and the first mounting plate is located at the upper side of the air outlet, so that the air can be guided to downwards discharge. Therefore, under the condition of large temperature difference, downward blowing is realized, and the indoor temperature is favorably and rapidly increased.
In step S32, when the air is blown downward, the third heating unit is controlled to be started in order to further increase the temperature increase rate. At this time, the first heating part, the second heating part and the third heating part play a heating role simultaneously, so that the temperature rising rate is quickly improved, and the constant-temperature dehumidification effect is further improved.
Optionally, the second temperature threshold is 5.5 ℃.
