Under the action of the auxiliary air inlet 123, air first enters the electrically controlled compartment 120 from the auxiliary air inlet 123 and then enters the second compartment 102 from the air inlet 107.

Alternatively, as shown in fig. 3, the electronically controlled compartment 120 includes a first partition 121 and a second partition 122. Wherein the first partition wall 121 is used as a partition wall provided with an air inlet 107 at the left side or the right side of the second compartment 102; the second partition wall 122 is perpendicular to the first partition wall 121 and parallel to the rear panel 106 of the cabinet 100, and is provided with an auxiliary air inlet 123.

In this embodiment, air from the rear side of the housing 100 enters the electrically controlled compartment 120 from the auxiliary air intake 123 and then enters the second compartment 102 from the air intake 107. An air circulation space is reserved between the electric cabinet and the first partition wall 121 and between the electric cabinet and the second partition wall 122, and circulated air can also play a role in cooling the electric cabinet, so that the normal operation of the electric cabinet is ensured.

Optionally, the air inlet 107 on the first partition 121 and the auxiliary air inlet 123 on the second partition 122 are disposed opposite to each other.

In this embodiment, the first partition wall 121 and the second partition wall 122 are vertically disposed, and the auxiliary air inlet 123 and the air inlet 107 are disposed opposite to each other, so that the air flow path can be shortened, and air can be quickly blown from the auxiliary air inlet 123 to the air inlet 107.

Optionally, a plurality of air inlets 107 are uniformly distributed on the first partition wall 121; the second partition wall 122 is provided with a plurality of auxiliary air inlets 123 which are uniformly distributed up and down.

Still another example, three air inlets 107 are provided on the first partition wall 121, and the three air inlets 107 are uniformly arranged up and down and are each configured as a circular opening. The second partition wall 122 is provided with three auxiliary air inlets 123, the three auxiliary air inlets 123 are uniformly distributed up and down and are all configured as round openings, and the three auxiliary air inlets 123 and the three air inlets 107 respectively correspond to each other.

Optionally, an air inlet 107 at the upper side of the second compartment 102 is provided at the rear of the upper panel 104 of the casing 100. The air inlet 107 at the lower side of the second chamber 102 is disposed on the lower panel 105 of the housing 100, and the air inlet 107 at the rear side of the second chamber 102 is disposed on the rear panel 106 of the housing 100.

In this embodiment, after the enclosure 100 is lifted, the upper panel 104 is closer to the roof, and the air inlet 107 is disposed at the rear of the upper panel 104, compared with the air inlet disposed at the middle and front of the upper panel 104, the air inlet is less affected by the wall.

Optionally, the air inlet 107 at the upper side of the second compartment 102 is configured as a strip-shaped opening.

In this embodiment, after the enclosure 100 is lifted, the upper panel 104 of the enclosure is closer to the roof, the air intake of the air inlet 107 at the upper side of the second chamber 102 is smaller than the air intake of the air inlets 107 at other sides, and the air inlet 107 at the upper side of the second chamber 102 is designed to be a long and narrow strip-shaped opening.

Optionally, a plurality of air inlets 107 are uniformly arranged on the upper side and the lower side of the second chamber 102. Thus, the number of the air inlets 107 is increased to increase the air inlet quantity.

Optionally, air inlet grids are provided at the air inlets 107 on the upper side, the lower side, the left side, the right side and the rear side of the second compartment 102. Thus, foreign matter is blocked from entering the second compartment 102 from the air inlet 107 by the air inlet grill.

Optionally, the air inlet 107 of the upper panel 104 of the housing 100 is referred to as a first air inlet, the air inlet 107 of the lower panel 105 is referred to as a second air inlet, the air inlet 107 of the rear panel 106 is referred to as a third air inlet, the air inlet 107 communicated with the electric control chamber 120 on one side is a fourth air inlet, and the air inlet 107 opposite to the fourth air inlet on the other side is a fifth air inlet. The air outlet area of the air outlet 108 of the casing 100 is A, the air inlet area of the first air inlet is 1/2A, the air inlet area of the second air inlet is A, the air inlet area of the third air inlet is A, the air inlet area of the fourth air inlet is 1/4A, and the air inlet area of the fifth air inlet is 1/4A. Here, the air intake area of the first air intake refers to the sum of the air intake areas of all the first air intake openings formed on the upper panel 104, and the air intake areas of the remaining second air intake openings to the fifth air intake opening are also the same.

In this embodiment, the proper air inlet 107 may be selectively plugged or opened according to the limitation of the installation space to meet different application scenarios, so that the sum of the air inlet areas of the air inlets 107 on different panels is greater than or equal to the air outlet area of the air outlet 108, and the indoor unit is maintained to operate at the normal wind speed.

Illustratively, the ducted air conditioner is mounted inside the television cabinet, and the upper and lower sides of the cabinet 100 have no air intake space. Under this scene, shutoff first air intake and second air intake open third air intake, fourth air intake and fifth air intake. Thus, the third air inlet is mainly used for air intake, and the fourth air inlet and the fifth air inlet are used for auxiliary air intake.

Still another exemplary, ducted air machines are mounted against the ceiling, with no air intake space on the upper side of the cabinet 100. Under this scene, the first air inlet is blocked, and the second air inlet to the fifth air inlet are opened.

Still another example, ducted air machines are installed in the bookcase, and the rear side and the lower side of the cabinet 100 have no air intake space. Under this scene, shutoff second air intake and third air intake open first air intake, fourth air intake and fifth air intake.

Optionally, the first air inlet to the fifth air inlet are all provided with wind shields, and the wind shields are movably arranged and cover or avoid the corresponding air inlets 107. The indoor unit has a breeze purification mode. Under breeze purification mode, the wind guard of first air intake, the wind guard of second air intake and the wind guard of third air intake are in shielding state, and the wind guard of fourth air intake and the wind guard of fifth air intake are in dodging state. Thus, the sum of the air inlet areas of the fourth air inlet and the fifth air inlet is 1/2 of the air outlet area of the air outlet 108, and the air speed is smaller. And the high-efficiency air filter screen at the fourth air inlet and the fifth air inlet is matched, so that a better purifying effect can be realized.

Optionally, the first air inlet to the fifth air inlet are all provided with wind shields, and the wind shields are movably arranged and cover or avoid the corresponding air inlets 107. The indoor unit provided by the embodiment of the disclosure meets the air inlet requirement under different scenes through the five-way air inlet design. However, since the second air inlet and the fifth air inlet are located close to the air outlet 108, there is a possibility that an air duct short circuit occurs, that is, cold air/hot air blown out from the air outlet 108 is not blown into the room, and is sucked into the casing 100 from the second air inlet or the fifth air inlet, which seriously affects the cooling/heating effect.

In this embodiment, in order to adjust the air intake policy in time when an air duct short circuit occurs, a control method of an indoor unit is provided:

s01: obtaining the temperature difference delta T1 between the air outlet and the fifth air inlet, obtaining the temperature difference delta T2 between the fifth air inlet and the fourth air inlet, and obtaining delta T1-delta T2 = T;

s02: judging whether the fifth air inlet is short-circuited or not according to T;

s03: under the condition that the fifth air inlet is short-circuited, the wind shield corresponding to the fifth air inlet is controlled to be in a shielding state, and the wind shield corresponding to the fourth air inlet is controlled to be in an avoiding state.

Wherein, the air outlet 108 and each air inlet 107 are provided with temperature sensors, so as to sense the temperatures of the corresponding air outlet 108 and air inlet 107. In this embodiment, when T is smaller than 0, it is determined that the short circuit occurs in the fifth air inlet. For example, the air conditioner operates in a cooling mode, the fourth air inlet is blocked, the fifth air inlet is open, the temperature of the air outlet 108 is 20 ℃, and the average indoor temperature is 30 ℃. In this case, if no short circuit occurs, the temperatures of the fourth air inlet and the fifth air inlet approach the indoor average temperature of 30 ℃, at this time Δt1=10, Δt2=0, and t=10. In this scenario, if a short circuit occurs, the temperature of the fifth air inlet approaches the temperature of the air outlet 108 by 20 ℃, the temperature of the fourth air inlet is 30 ℃, Δt1=0, Δt2=10, and t= -10. And the air inlet areas of the fourth air inlet and the fifth air inlet are the same, if the fifth air inlet is short-circuited, the fourth air inlet is used for air inlet, and the initial air inlet quantity can be maintained while the short circuit of the air duct is solved. It will be appreciated that if the second air inlet is shorted, the third air inlet may be used to enter air, and the short circuit determination and the control of the wind deflector are the same as the control method described above.

Optionally, the embodiment of the disclosure provides another control method of an indoor unit:

s04: acquiring the change rate Deltav 1 of the temperature difference between the air outlet and the second air inlet, and acquiring the change rate Deltav 2 of the indoor temperature, wherein Deltav 1-Deltav2=V;

s05: judging whether the second air inlet is short-circuited or not according to the V;

s06: under the condition that the second air inlet is short-circuited, the wind shield corresponding to the second air inlet is controlled to be in a shielding state, and the wind shield corresponding to the third air inlet is controlled to be in an avoiding state.

Wherein, the air outlet 108 and each air inlet 107 are provided with temperature sensors, so as to sense the temperatures of the corresponding air outlet 108 and air inlet 107. In this embodiment, when V is out of the preset difference range, it is determined that the second air inlet is shorted. And the air inlet areas of the second air inlet and the third air inlet are the same, if the second air inlet is short-circuited and the third air inlet is used for air inlet, the initial air inlet quantity can be maintained while the short circuit of the air duct is solved. It will be appreciated that if the fifth air inlet is shorted, the fourth air inlet may be used to enter air, and the short circuit determination and the control of the wind deflector are the same as the control method described above.
