A floor type air conditioner indoor unit 1 according to an embodiment of the present invention will be described with reference to the accompanying drawings.

As shown in fig. 1 to 10, the indoor unit 1 of a floor air conditioner according to the embodiment of the present invention includes a casing 100, a heat exchanger, a fan, a longitudinal air guide plate 400, a sensor 200, and a controller 300.

The casing 100 has an air inlet and an air outlet, the heat exchanger is installed in the casing 100, the blower is installed in the casing 100, and is used for guiding air to enter the casing 100 from the air inlet and exchange heat with the heat exchanger, and then exhaust from the air outlet, the longitudinal air deflector 400 is rotatably installed in the casing 100 and located at the air outlet, a rotation axis of the longitudinal air deflector extends along an axial direction of the casing 100, by rotation of the longitudinal air deflector 400, a flow direction of the air exhausted from the air outlet is adjusted, the longitudinal air deflector 400 has at least three boundary positions 410 within a rotation range, two adjacent boundary positions 410 define an air guiding area, the sensor 200 is installed in the casing 100 and is used for detecting a user position, the controller 300 is installed in the casing 100 and is respectively connected with the longitudinal air deflector 400 and the sensor 200, and the controller 300 is configured to: when the controller 300 receives the first control signal, the controller 300 obtains the user position fed back by the sensor 200, and compares the user position with at least three dividing positions 410, if the user position is located between two adjacent dividing positions 410 in the rotation direction of the longitudinal air guiding plate 400, the controller 300 controls the longitudinal air guiding plate 400 to rotate disorderly in a plurality of air guiding areas, so that the air volume in the air guiding area corresponding to the user position is not larger than the air volume in any one of the other air guiding areas and is smaller than the air volume in at least one of the other air guiding areas.

Wherein the first control signal enables the floor air conditioner 1 to enter a natural wind mode.

When the user position is located on the dividing position 410 in the rotation direction of the longitudinal air deflector 400, the user position may be assigned to the right air guiding area adjacent to the user position according to the left-to-right direction of the indoor unit 1 of the vertical air conditioner, or the user position may be assigned to the left air guiding area adjacent to the user position according to the right-to-left direction of the indoor unit 1 of the vertical air conditioner, or may be adjusted according to the actual situation, for example, a part of the dividing position 410 may belong to the left air guiding area, and another part of the dividing position 410 belongs to the right air guiding area. Of course, it is understood that the air guiding area is provided on only one side of each of the leftmost boundary position 410 and the rightmost boundary position 410, and the leftmost boundary position 410 may be assigned to the air guiding area adjacent thereto, and the rightmost boundary position 410 may be assigned to the air guiding area adjacent thereto.

For example, when the longitudinal air guiding plate 400 of the floor air conditioner indoor unit 1 is turned between two adjacent dividing positions 410, the longitudinal air guiding plate 400 guides the air-conditioned air to the air guiding area. The extending direction of the air outlet of the indoor unit 1 of the floor air conditioner is the circumferential extending direction of the floor air conditioner, i.e. the horizontal extending direction.

According to the indoor unit 1 of the floor air conditioner of the embodiment of the present invention, the sensor 200 is installed on the casing 100 to detect the user position, for example, the sensor 200 may be an infrared sensor, and further, the user position may be detected by the infrared sensor, and a user position signal is transmitted to the controller 300, and the controller 300 compares the user position with the dividing position 410 to determine the air guiding area corresponding to the user position.

In addition, when the air conditioner receives the first control signal, the controller 300 obtains the user position fed back by the sensor 200, and compares the user position with at least three boundary positions 410, if the user position is located between two adjacent boundary positions 410 in the rotation direction of the longitudinal air deflector 400, the controller 300 controls the longitudinal air deflector 400 to rotate disorderly according to the user position, so that on one hand, the air conditioning air can be blown closer to natural air and more comfortable to air outlet by controlling the longitudinal air deflector 400 to rotate disorderly, on the other hand, the air conditioning air can be blown to the air guiding area where the current user is located less in the disorderly blowing state by controlling the longitudinal air deflector 400, thereby preventing too much air conditioning air from blowing to the body of the user, ensuring better air conditioning blowing feeling, and better user experience.

In addition, the air volume in the air guiding area corresponding to the user position is not greater than the air volume in any one of the other air guiding areas and is less than the air volume in at least one of the other air guiding areas, that is, the air guiding quantity in the air guiding area corresponding to the user position can be the minimum, and the air guiding quantity in at least one air guiding area is greater than the air guiding quantity in the air guiding area corresponding to the user position, so that the longitudinal air guide plate 400 can blow more air-conditioned air into the air guiding area with the maximum air guiding quantity, thereby blowing the air-conditioned air indoors, ensuring the sufficient air quantity of the air-conditioned air to achieve the purpose of indoor cooling or heating more quickly, simultaneously preventing a large amount of air-conditioned air from blowing into the area where the user is located, preventing the air-conditioned air from blowing directly to the user, and ensuring better comfortable air blowing for the user.

Moreover, the air volume in the air guide area corresponding to the user position is not greater than the air volume in any of the other air guide areas, that is, the air volume in the air guide area corresponding to the user position is smaller than the air volume in the other air guide areas, rather than no air volume in the air guide area corresponding to the user position, and it is also ensured that air conditioning air blows through the air guide area while ensuring that the air volume in the air guide area corresponding to the user position is smaller, so that the air outlet of the indoor unit 1 of the floor air conditioner is closer to the natural air blowing mode.

In addition, the controller 300 may adjust the rotation mode of the longitudinal air guiding plate 400 by continuously acquiring the user position information detected by the sensor 200, so that the rotation of the longitudinal air guiding plate 400 may consider the information of the user movement, and the longitudinal air guiding plate 400 is prevented from rotating in the previous rotation mode after the user position is changed, thereby ensuring that the air-conditioned air is less blown to the user, and improving the blowing experience of the user.

Thus, the air outlet of the indoor unit 1 of the floor air conditioner according to the embodiment of the invention can imitate natural wind, so that the air conditioning wind blows less to users, and the floor air conditioner has the advantages of strong disorder, comfortable air blowing and the like.

In some embodiments of the invention, as shown in fig. 1-6, the controller 300 is configured to: when the controller 300 receives the first control signal, if the user position is not located between any two dividing positions 410 in the rotation direction of the longitudinal air guiding plate 400, the longitudinal air guiding plate 400 is controlled to rotate in disorder in a plurality of air guiding areas, so that the air volume in the plurality of air guiding areas is different.

It can be understood that the air outlet can only extend a part along the circumferential direction of the indoor unit 1 of the floor air conditioner, rather than completely surrounding the circumferential direction of the indoor unit 1 of the floor air conditioner, that is, in the circumferential direction or the length direction of the indoor unit 1 of the floor air conditioner, the air guiding range of the indoor unit 1 of the floor air conditioner can only correspond to a part of the indoor area, and the other part of the indoor area belongs to the blowing blind area, and the air conditioning air can not blow directly into the user, if the user is in the blowing blind area, the air conditioning air can not blow directly into the user, but the air conditioning air can also drive the air flow to flow and influence the blowing body feeling of the user, and at this time, the air conditioning air can still be close to the natural air by controlling the longitudinal air deflector 400 to rotate disorderly, so that the air conditioning air can be simulated into the natural air, further avoiding the discomfort of the user caused by the blowing of the air conditioning air, and the user experience is better.

In addition, if the first control signal is received during the normal operation of the indoor unit 1 of the floor air conditioner to turn on the natural wind mode, that is, when the indoor unit 1 of the floor air conditioner is normally cooling, heating or blowing, the user switches the operation mode of the indoor unit 1 of the floor air conditioner to the natural wind mode, the longitudinal air guiding plate 400 is reset (for example, the longitudinal air guiding plate 400 is rotated to the direction perpendicular to the air outlet), and then the indoor unit 1 of the floor air conditioner detects the air guiding area where the user is located, and controls the longitudinal air guiding plate 400 to rotate in an unordered manner.

If the first control signal is received immediately when the floor air conditioner indoor unit 1 is started up, so as to start the natural wind mode, if the floor air conditioner indoor unit 1 is in the refrigeration or air supply mode, the longitudinal air deflector 400 is reset (for example, the longitudinal air deflector 400 is rotated to the direction perpendicular to the air outlet), then the floor air conditioner indoor unit 1 detects the air guide area where the user is located, and controls the longitudinal air deflector 400 to rotate disorderly;

if the indoor unit 1 of the floor air conditioner is powered on to heat, at this time, the indoor unit 1 of the floor air conditioner immediately receives the first control signal, that is, the user immediately switches the operation mode of the indoor unit 1 of the floor air conditioner to the natural wind mode, the indoor unit 1 of the floor air conditioner firstly prevents cold wind, prevents the outlet wind before heating from being cold wind and directly blowing the body of the user, and after the cold wind is prevented, the longitudinal air deflector 400 is reset (for example, the longitudinal air deflector 400 is rotated to the direction perpendicular to the air outlet), and then the indoor unit 1 of the floor air conditioner detects the air guiding area where the user is located, and controls the longitudinal air deflector 400 to rotate disorderly.

It can be understood that when the vertical air conditioner indoor unit 1 is just turned on to operate in the heating mode, hot air cannot be blown out immediately, a part of cold air or air conditioning air with a temperature close to the indoor temperature can be blown out from the vertical air conditioner indoor unit 1, the cold air prevention means that the longitudinal air deflector 400 and the transverse air deflector are rotated to the positions inclined relative to the air outlet so as to discharge the part of air conditioning air and prevent the part of air conditioning air from blowing to the body of a user, when the vertical air conditioner indoor unit 1 starts to heat and can blow out hot air, the cold air prevention is turned off, and the longitudinal air deflector 400 is controlled to rotate in disorder according to the air guiding area where the user is located after being reset, so that the air blowing experience of the user is further improved, and the air blowing comfort level is higher.

Certainly, the above-mentioned rotation mode of controlling the longitudinal air deflector is not only suitable for the vertical air conditioner indoor unit 1 to receive the first control signal immediately when the air conditioner indoor unit 1 is started to heat, and if the vertical air conditioner indoor unit 1 is switched from the air supply mode to the heating mode and receives the first control signal, the vertical air conditioner indoor unit 1 can also be controlled to prevent cold wind first, and after the cold wind is prevented, the longitudinal air deflector 400 is controlled to reset and then rotates disorderly according to the air guide area where the user is located, so that the air blowing experience of the user is better improved.

In some embodiments of the present invention, as shown in fig. 2 to fig. 5, the plurality of wind guide areas at least include a first area 700, a second area 800, and a third area 900 sequentially arranged along a horizontal direction;

the controller 300 is configured to: when receiving the first control signal, the controller 300 compares the current user position with the boundary position 410 on both sides of the first area 700, the boundary position 410 on both sides of the second area 800, and the boundary position 410 on both sides of the third area 900 in the rotation direction of the longitudinal air guiding plate 400;

if the user position is located between the boundary positions 410 at the two sides of the first area 700 in the rotation direction of the longitudinal air guiding plate 400, that is, the user position is located in the first area 700, the longitudinal air guiding plate 400 is controlled to rotate circularly in the third area 900 for a first preset number of times, then rotates circularly in the whole of the first area 700 and the second area 800 for a second preset number of times, and repeats the first preset period;

if the user position is located between the boundary positions 410 on the two sides of the second area 800 in the rotation direction of the longitudinal air guiding plate 400, that is, the user position is located in the second area 800, the longitudinal air guiding plate 400 is controlled to rotate circularly in one of the first area 700 and the third area 900 for a third preset number of times, then the other one of the first area 700 and the third area 900 and the second area 800 rotate circularly in the whole for a fourth preset number of times, and a second preset period is repeated;

if the user position is located between the boundary positions 410 at the two sides of the third area 900 in the rotation direction of the longitudinal air guiding plate 400, that is, the user position is located in the third area 900, the longitudinal air guiding plate 400 is controlled to rotate circularly in the first area 700 for a fifth preset number of times, and then rotates circularly in the second area 800 and the third area 900 for a sixth preset number of times, and the third preset period is repeated.

Specifically, after the longitudinal air deflector 400 repeats the first preset period, the second period or the third period, the vertical air conditioner indoor unit 1 detects the position of the user again, and adjusts the rotation mode of the longitudinal air deflector 400 again according to the air guiding area where the user is located, so that the air supply of the vertical air conditioner indoor unit 1 can take the user moving factor into consideration, the rotation mode of the longitudinal air deflector 400 can be adjusted in time, and the air blowing experience of the user is further improved.

For example, the first preset number, the second preset number, the third preset number, the fourth preset number, the fifth preset number, and the sixth preset number may be the same or different, and for example, the first preset number, the second preset number, the third preset number, the fourth preset number, the fifth preset number, and the sixth preset number may be 3.

The repeating of the first preset period refers to that the longitudinal air deflector 400 is rotated in the third area 900 for a first preset number of times in a circulating manner, and then rotated in the first area 700 and the second area 800 for a second preset number of times in a circulating manner; the repetition of the second preset period means that the longitudinal air deflector 400 is repeatedly rotated in one of the first area 700 and the third area 900 for a third preset number of times, and then rotated in the other of the first area 700 and the third area 900 and the second area 800 for a fourth preset number of times; the third preset period is repeated, in which the longitudinal air guiding plate 400 is repeatedly rotated for a fifth preset number of times in the first area 700, and then rotated for a sixth preset number of times in the second area 800 and the third area 900 as a whole.

And, the circulation rotation in the whole of the first and second regions 700 and 800 means that the longitudinal wind deflectors 400 pass through the first and second regions 700 and 800 and rotate back and forth in the first and second regions 700 and 800; the circulation rotation in the entirety of the second and third sections 800 and 900 means that the longitudinal wind deflectors 400 pass through the second and third sections 800 and 900 and rotate back and forth in the second and third sections 800 and 900.

In this way, the longitudinal air deflector 400 rotates in a circulating manner in the air guiding area outside the position of the user, and then rotates in a circulating manner in the whole of the air guiding area outside the position of the user and the other air guiding area adjacent to the air guiding area, so that the air volume in the air guiding area outside the position of the user is larger in unit time, and because the longitudinal air deflector 400 rotates in a circulating manner in the whole of the air guiding area at the position of the user and the other air guiding area adjacent to the air guiding area, that is, air conditioning air is intermittently blown into the air guiding area at the position of the user instead of always being always blown into the air guiding area, the air volume in the air guiding area is smaller, so that the air conditioning air directly blowing the body of the user is reduced, the rotation disorder of the air conditioning air in the air guiding areas is stronger, true natural air can be simulated, and the air blowing experience of the user can be improved.

Moreover, by setting the preset times, the continuous cycle rotation times of the longitudinal air deflector 400 in a single air guiding area can be controlled, so that the longitudinal air deflector 400 can rotate sufficiently in the single air guiding area, the air conditioning wind of the vertical air conditioner indoor unit 1 can be controlled to blow into the appointed air guiding area, the direction change of the air conditioning wind in the single air guiding area is controlled, the disorder is stronger, and the air conditioning wind is closer to the blowing mode of natural wind.

In addition, by setting a preset period, the number of rotation periods of the longitudinal air deflector 400 can be controlled, when the number of rotation periods of the longitudinal air deflector 400 reaches the set number of rotation periods, the vertical air conditioner indoor unit 1 can detect the user position again, when the user moves to change the current user position, for example, the user moves from the first area 700 to the second area 800 or the third area 900, or the user moves from the second area 800 to the first area 700 or the third area 900, or the user moves from the third area 900 to the first area 700 or the second area 800, or the user moves from the air guiding area to the outside of the air guiding areas, or the user moves from the outside of the air guiding areas to the inside of the air guiding areas, and the vertical air conditioner indoor unit 1 can detect the position change of the user in real time, thereby switching the rotation manner of the longitudinal air deflector 400 to adapt to the position movement of the user, further improving the air conditioning experience of the user, avoiding the air conditioning wind from being directly blown by the user movement, and providing more comfortable air conditioning.

In some embodiments of the invention, as shown in fig. 2 and 6, the controller 300 is configured to: when the controller 300 receives the first control signal, if the user position is not located between any two adjacent dividing positions 410 in the rotation direction of the longitudinal air guiding plate 400, that is, the user position is not located in the multiple air guiding areas, the longitudinal air guiding plate 400 is controlled to rotate circularly in one of the first area 700 and the third area 900 for a seventh preset number of times, the longitudinal air guiding plate 400 is controlled to rotate circularly in the other of the first area 700 and the third area 900 and the whole second area 800 for an eighth preset number of times, and a fourth preset period is repeated.

Specifically, after the longitudinal air deflector 400 repeats the fourth cycle, the vertical air conditioner indoor unit 1 detects the user position again through the sensor 200, and compares the user position with the boundary position 410 on the two sides of the first area 700, the boundary position 410 on the two sides of the second area 800 and the boundary position 410 on the two sides of the third area 900 in the rotation direction of the longitudinal air deflector 400, so as to adjust the rotation mode of the longitudinal air deflector 400 again according to the air guiding area where the user is located in real time, so that the air supply of the vertical air conditioner indoor unit 1 can take the user movement factor into consideration, and thus the rotation mode of the longitudinal air deflector 400 can be adjusted in time, and the air blowing experience of the user is further improved.

For example, the seventh preset number and the eighth preset number may be the same or different, and for example, both the seventh preset number and the eighth preset number may be 3.

The repetition of the fourth preset period refers to that the longitudinal air guiding plate 400 rotates circularly in one of the first area 700 and the third area 900 for a seventh preset number of times, and then rotates circularly in the other of the first area 700 and the third area 900 and the second area 800 for an eighth preset number of times. Also, the rotation circulating within the other of the first and third sections 700 and 900 and the second section 800 as a whole means that the longitudinal wind deflectors 400 pass through the other of the first and third sections 700 and 900 and the second section 800 and rotate back and forth within the other of the first and third sections 700 and 900 and the second section 800.

That is, when the user is inside the second area 800 or outside the plurality of air guiding areas, the longitudinal air guiding plates 400 may be rotated in the first area 700 or in the third area 900.

In this way, even if the user is not in the air guiding area, the longitudinal air guide plate 400 can control the air conditioning air to simulate the blowing mode of natural air, so as to reduce the influence of the air conditioning air on the indoor air flow, further avoid discomfort of the user caused by air outlet of the air conditioner, and achieve better user experience.

In some embodiments of the present invention, as shown in fig. 7 and 8, the angles of the demarcation locations 410 on both sides of the first zone 700, the angles of the demarcation locations 410 on both sides of the second zone 800, and the angles of the demarcation locations 410 on both sides of the third zone 900 are equal. In this way, the sizes of the first area 700, the second area 800 and the third area 900 can be ensured to be the same, and by controlling the rotation speeds of the longitudinal air deflectors 400 to be the same, the time for the longitudinal air deflectors 400 to pass through each air guiding area in a single rotation can be controlled to be the same, so that the air guiding amount of the longitudinal air deflectors 400 passing through each air guiding area in a single rotation is the same, and the control is convenient.

In some embodiments of the invention, the first preset number is not less than the second preset number, the third preset number is not less than the fourth preset number, the fifth preset number is not less than the sixth preset number, and the seventh preset number is not less than the eighth preset number.

That is to say, the first preset number of times may be greater than the second preset number of times, the third preset number of times may be greater than the fourth preset number of times, the fifth preset number of times may be greater than the sixth preset number of times, and the seventh preset number of times may be greater than the eighth preset number of times, so that the longitudinal air deflectors 400 may rotate more times in the air guiding area outside the air guiding area where the user is located, so that the air-conditioning air may blow more toward the air guiding area outside the air guiding area where the user is located, further reducing the air-conditioning air blowing directly to the user, and making the air blowing more comfortable.

Of course, the first preset number and the second preset number may be the same, the third preset number and the fourth preset number may be the same, the fifth preset number and the sixth preset number may be the same, and the seventh preset number and the eighth preset number may be the same; or the first preset number, the second preset number, the third preset number, the fourth preset number, the fifth preset number, the sixth preset number, the seventh preset number and the eighth preset number may be the same.

In some embodiments of the present invention, the first preset period, the second preset period, the third preset period and the fourth preset period are equal to and greater than 1.

For example, the first predetermined period, the second predetermined period, the third predetermined period, and the fourth predetermined period are equal and may be 2, 3, 4, or 5. In this way, no matter which air guiding area the current user position is in or outside, the number of rotation cycles of the longitudinal air guiding plate 400 may be the same, so that the rotation time of the longitudinal air guiding plate 400 in different rotation modes is the same, and the amount of air guiding into the room after detecting the user position once is the same.

Moreover, after the position of the current user is detected, the longitudinal air deflector 400 is controlled to rotate for at least two periods, so that the position of the current user is prevented from being frequently detected, the rotation state of the longitudinal air deflector 400 is prevented from being frequently switched, and the rotation of the longitudinal air deflector 400 is facilitated to be simplified.

In some embodiments of the present invention, the longitudinal air guiding plate 400 has a first limit position 420 and a first limit position 430 in the rotation direction, both the first limit position 420 and the first limit position 430 are the boundary position 410, and the area corresponding to the included angle between the first limit position 420 and the first limit position 430 is adapted to the air outlet in the rotation direction of the longitudinal air guiding plate 400. Like this, the wind-guiding coverage of vertical aviation baffle 400 can suit with the coverage of air outlet, the length of air outlet can not set up too big, the structure sets up more rationally, and vertical aviation baffle 400 can be with air conditioner wind along a plurality of positions in the horizontal extending direction guide room of air outlet, and, can avoid vertical aviation baffle 400 to take place the position with the lateral wall of air outlet and interfere when rotating, the air outlet can not shelter from the air conditioner wind that vertical aviation baffle 400 water conservancy diversion was said simultaneously, so that the air-out of vertical air conditioner indoor unit 1 is more unobstructed.

In other particular embodiments of the present invention, the controller 300 is configured to: when the controller 300 receives the first control signal, if the user position is located between two adjacent boundary positions 410 in the rotation direction of the longitudinal air guiding plate 400, the longitudinal air guiding plate 400 is controlled to rotate in an unordered and cyclic manner in a plurality of air guiding areas, and the number of times of the cyclic rotation of the longitudinal air guiding plate 400 in the air guiding area corresponding to the user position is smaller than the number of times of the cyclic rotation of the longitudinal air guiding plate 400 in any one of the other air guiding areas.

That is to say, the number of times of the circular rotation of the longitudinal air guiding plate 400 in the air guiding area corresponding to the user position is the least, so that in a single period, the amount of air guided by the longitudinal air guiding plate 400 into the air guiding area corresponding to the current user position is the least, air conditioning air blowing directly to the body of the user is further reduced, and the user experience is better.

Thus, in some embodiments, the user may control and adjust the operation mode of the indoor unit 1 of the floor air conditioner via the keys on the remote control device 500. In other embodiments, the user can also control and adjust the operation mode of the floor air conditioner indoor unit 1 by directly touching the control switch 600 on the casing 100 of the floor air conditioner indoor unit 1, which is more convenient for the user to use.

Other constructions and operations of the floor air conditioner indoor unit 1 and the floor air conditioner indoor unit 1 according to the embodiments of the present invention are known to those skilled in the art and will not be described in detail herein.

The floor air conditioner indoor unit 1 in this application performs a refrigeration cycle of the floor air conditioner indoor unit 1 by using a compressor, a condenser, an expansion valve, and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies refrigerant to the air that has been conditioned and heat-exchanged.

The compressor compresses a refrigerant gas in a high-temperature and high-pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.

The expansion valve expands the liquid-phase refrigerant in a high-temperature and high-pressure state condensed in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a cooling effect by heat-exchanging with a material to be cooled using latent heat of evaporation of a refrigerant. Throughout the cycle, the floor air conditioner indoor unit 1 can adjust the temperature and humidity of the indoor space.
