Fig. 1 is a schematic structural view of an indoor unit of a wall-mounted air conditioner according to an embodiment of the present invention; fig. 2 is a schematic cross-sectional view of an air outlet in an indoor unit of a wall-mounted air conditioner in a closed state according to an embodiment of the present invention; fig. 3 is a schematic cross-sectional view of an indoor unit of a wall-mounted air conditioner according to an embodiment of the present invention when an air outlet area is a second predetermined value; fig. 6 is a schematic block diagram of connection of an indoor unit of a wall-mounted air conditioner according to an embodiment of the present invention.
Referring to fig. 1 and 2, in the present embodiment, the wall-mounted air conditioner indoor unit includes a housing 100, a first air guide plate 210, and a second air guide plate 220. The casing 100 is provided with an air outlet 110 facing the front; the first air deflector 210 and the second air deflector 220 are rotatably disposed at the air outlet 110, the air outlet 110 has a closed state jointly closed by the first air deflector 210 and the second air deflector 220, and the first air deflector 210 is located above the second air deflector 220.
In the present embodiment, the case 100 includes a front panel 120 defining a front appearance of the indoor unit, a front side panel 150, a rear side panel 180, a left side panel 130 defining a left side appearance of the indoor unit, a right side panel defining a right side appearance of the indoor unit, a top side panel 160, and a bottom side panel 140 defining a bottom appearance of the indoor unit, and the front panel 120 is openably located in front of the case 100. The rear side plate 180 may be a mounting plate on which the indoor unit of the air conditioner is mounted to a wall of the indoor space. The air outlet 110 may be opened between the front side plate 150 and the bottom side plate 140.
Referring to fig. 1, 2 and 3, in the present embodiment, for convenience of explanation and understanding of the following embodiments, it is defined that the top of the first air deflector 210 in the closed state of the air outlet 110 is the first side 211, the bottom of the first air deflector 210 in the closed state of the air outlet 110 is the second side 212, the top of the second air deflector 220 in the closed state of the air outlet 110 is the third side 221, and the bottom of the second air deflector 220 in the closed state of the air outlet 110 is the fourth side 222. Therefore, the above-mentioned definition is not considered as limiting the actual protection scope of the present invention.
It can be appreciated that the first air deflector 210 and the second air deflector 220 in this embodiment have a plurality of air guiding states, so that the direction of the air flow of the air outlet 110 can be limited. Moreover, since the air outlet 110 is jointly closed by the first air deflector 210 and the second air deflector 220, the air flow from the air outlet of only one air deflector can still flow into the indoor space from the other air deflector which is not closed, so that the first air deflector 210 can be in a state of being capable of guiding the air flow of the air outlet to flow downwards.

And detecting whether the operation mode of the air conditioner indoor unit is a cooling mode.

At this time, the temperature of the indoor space is not lowered too fast or too slow, so that the air conditioner indoor unit is more easily adapted to the user when the normal cooling mode is switched to the anti-direct-blowing mode of the first predetermined value. Meanwhile, in the process that the air conditioner indoor unit is switched from the direct blowing prevention mode with the first preset value to the direct blowing prevention mode with the air outlet area being other preset values, the value of increasing or decreasing the air outlet area is not very large, and a user can be well adapted to the direct blowing prevention modes with different air outlet areas of the air conditioner indoor unit or well adapted to the air conditioner indoor unit to be switched among a plurality of direct blowing prevention modes, so that the user is gradually adapted to the direct blowing prevention modes with the plurality of air outlet areas of the air conditioner indoor unit. Therefore, the buffer period for the user to enter the anti-direct-blowing mode from the normal cooling mode can be given to the user, and the user experience of the indoor unit of the air conditioner is further improved.
In addition, the preset time length can be preferably three minutes, so that the user can adapt to the direct blowing prevention mode, the user cannot experience a longer buffering period, the current indoor space temperature cannot immediately approach the set temperature and feel uncomfortable, and the user experience is guaranteed.
Referring to fig. 8, in the present embodiment, after controlling the indoor unit of the air conditioner to operate for a preset period of time in step S814, step S704, controlling the first air deflector 210 to rotate to a state of guiding the outlet air flow downward, and controlling the second air deflector 220 to rotate further includes:
step S816, detecting an ambient temperature of a space in which the indoor unit of the air conditioner is located.
It should be understood that the present embodiment may detect the ambient temperature by the temperature sensor 530 in the above embodiment.
Step S818, controlling the first air deflector 210 and the second air deflector 220 to rotate according to the difference between the ambient temperature and the preset temperature so as to adjust the air outlet area; the first air deflector 210 is always in a state of guiding the air-out airflow downward.
Because the method in this embodiment can control the first air deflector 210 and the second air deflector 220 to rotate according to the difference between the ambient temperature and the preset temperature to adjust the air outlet area in the direct blowing prevention mode, the rate of adjusting the temperature of the indoor unit of the air conditioner to the indoor space is adapted to the requirement of the user, and the user experience is further improved.
It can be appreciated that the preset temperature is a temperature value set by the user according to his own will, and the control method in this embodiment can control the first air deflector 210 and the second air deflector 220 to rotate according to the detected difference between the ambient temperature in the indoor space and the preset temperature to adjust the air outlet area, so as to achieve the beneficial technical effect that the speed of the air conditioner indoor unit for adjusting the temperature of the indoor space adapts to the requirement of the user.

S902, obtaining a corresponding relation between a preset difference value and a preset area value of the air outlet area.
S904, determining a preset area value corresponding to the difference value according to the corresponding relation.
S906, controlling the first air deflector 210 and the second air deflector 220 to rotate so that the air outlet area is a preset area value corresponding to the difference value.
It can be understood that the corresponding relation can be obtained by a person skilled in the art through multiple tests, that is, whether the preset difference value can be reduced to 0 in a certain period of time is tested, if not, the preset air outlet area is replaced until the preset difference value can be reduced to 0 corresponding air outlet area is tested, and then the preset difference value is replaced, and the test is repeated, so that the corresponding relation between the preset difference value and the preset area value of the air outlet area can be obtained.
In this embodiment, the correspondence relationship is represented by the decrease of the preset area value with the stepwise decrease or continuous decrease of the preset difference value.
It should be appreciated that the stepwise decline may be represented by a predetermined difference range for a previous entity being greater than a predetermined difference range for a subsequent entity, and the continuous decline may be represented by a predetermined difference value being greater than a subsequent predetermined difference value. And, preset area value reduces along with the stepwise decline or the continuous decline of preset difference, shows that the smaller the difference, the lower the rate that the temperature that the user needs reduces, the smaller the air-out area that needs, and then the air conditioner indoor set is according to this correspondence table control first aviation baffle 210 and second aviation baffle 220 in order to adjust the air-out area can adapt to user's demand well, guarantees user experience.
Referring to fig. 3, 4 and 5, in the present embodiment, the state of guiding the air-out airflow downward includes a first state in which the first air deflector 210 rotates such that the first side 211 is located in the avoidance gap 170 and a second state in which the first side 211 abuts against the front side plate 150 of the housing 100.
Referring to fig. 3, 4 and 5, in one implementation of the correspondence relationship in this embodiment, the correspondence relationship includes:
Under the condition that the preset difference value is greater than the first preset value and less than or equal to the second preset value, the first air deflector 210 is controlled to rotate to a second state, the second air deflector 220 is controlled to sweep air and rotate, and the third side 221 is controlled to always face the air outlet 110, so that an air outlet area is defined between the second side 212 and the second air deflector 220, between the second air deflector 220 and the bottom end of the air outlet 110, and between the two sides of the air outlet 110 to be a second preset value.
It should be understood that, when the preset difference value is greater than the first preset value and less than or equal to the second preset value, the first air deflector 210 is already in the second state, so that the direct blowing preventing function of the indoor unit of the air conditioner can be realized, and meanwhile, the second air deflector 220 can perform wind sweeping rotation to improve the air supply range of the indoor unit of the air conditioner in the direct blowing preventing mode, further improve the speed of the indoor unit of the air conditioner for adjusting the indoor space temperature, and ensure the refrigerating capacity of the indoor unit of the air conditioner under the condition.
Under the condition that the preset difference is equal to the first preset value, the first air deflector 210 is controlled to rotate to a first state, and the second air deflector 220 is controlled to rotate to a state that the fourth side 222 faces the air outlet 110, so that an air outlet area is defined between the second side 212 and the third side 221, between the fourth side 222 and the bottom end of the air outlet 110, and between the two sides of the air outlet 110 to be a first preset value.
And when the preset difference is smaller than the first preset value and equal to or greater than the third preset value, controlling the air deflector to rotate to a second state, and controlling the second air deflector 220 to rotate to a state that the fourth side 222 faces the air outlet 110, so as to define an air outlet area as a third preset value between the second side 212 and the third side 221, between the fourth side 222 and the bottom end of the air outlet 110, and between the two sides of the air outlet 110.
The second preset value is larger than the first preset value, and the first preset value is larger than the third preset value; the second predetermined value is greater than the first predetermined value, and the first predetermined value is greater than the third predetermined value.
In addition, it can be appreciated that the air outlet area can be adjusted to a corresponding required preset air outlet area by controlling the states of the first air deflector 210 and the second air deflector 220 in the present embodiment. For example, in the step of controlling the first air deflector 210 to rotate to a state of guiding the air-out airflow downward and controlling the second air deflector 220 to rotate so that the air-out area is a first predetermined value, the first air deflector 210 may be controlled to rotate to a first state and the second air deflector 220 may be controlled to rotate to a state that the fourth side 222 faces the air-out opening 110, so as to define the air-out area between the second side 212 and the third side 221, between the fourth side 222 and the bottom end of the air-out opening 110, and between the two sides of the air-out opening 110 as the first predetermined value.
In this embodiment, the first preset value may be 0, that is, the difference between the ambient temperature and the preset temperature is 0.
Because the difference between the ambient temperature and the preset temperature is 0, the ambient indoor temperature has reached the temperature value set by the user, at this time, the cooling rate corresponding to the first preset value is appropriate, the air outlet is softer while the consistency between the indoor temperature and the temperature set by the user can be better maintained, after the air outlet enters the direct-blowing prevention mode, the first air deflector 210 and the second air deflector 220 are controlled to rotate according to the difference between the ambient temperature and the preset temperature, so that the first air deflector 210 and the second air deflector 220 of the indoor unit of the air conditioner are controlled to adjust the air outlet area to the first preset value before the air outlet area is adjusted, the user can adapt to the switching from the normal refrigeration mode to the direct-blowing prevention mode in which the air outlet area is forcibly adjusted to the first preset value more easily, so that the user can accept or adapt to the switching between the multiple direct-blowing prevention modes in which the air outlet area is adjusted according to the difference, and the user experience is further ensured.
And, under the condition that the difference value is the second preset value, the ambient temperature is greater than the preset temperature, at this time, the indoor unit of the air conditioner needs to have larger refrigerating capacity, and the ambient temperature needs to be quickly brought to the preset temperature, so the second preset value is greater than the first preset value; under the condition that the difference value is a third preset value, the ambient temperature is smaller than the preset temperature, the temperature of the indoor space is required to gradually rise to the preset temperature, and the smaller refrigerating capacity of the indoor unit of the air conditioner is required, so that the first preset value is larger than the third preset value.
