As shown in fig. 13, 14 and 23, the indoor unit further includes an electric control board 910, and the electric control board 910 is used for controlling the operation of various electric components of the air conditioner. Because the electric control board 910 generates heat during operation, if the heat is not timely dissipated, the temperature of the electric control board 910 is increased, the electric control board 910 is easily burnt, and the indoor unit cannot work normally.

Therefore, the indoor unit further includes a radiator 920, and the radiator 920 is disposed near the electric control board 910 to dissipate heat generated when the electric control board 910 operates. The radiator 920 installed in the indoor unit of the current air conditioner generally dissipates heat by using air, and the air contacts the radiator 920 and exchanges heat with the radiator 920, so that the temperature of the air increases, and the heat of the radiator 920 is reduced.

At present, the electric control board 910 is usually installed in the electric box 900, the electric box 900 protects the electric control board 910, and prevents water, dust and impurities from contacting the electric control board 910, and because the radiator 920 needs to be close to the electric control board 910, the radiator 920 is also installed in the electric box 900, and the electric box 900 comprises a heat dissipation air inlet 901 and a heat dissipation air outlet 902, so that air can enter the electric box 900 from the heat dissipation air inlet 901 and then be output from the heat dissipation air outlet 902 after contacting the heat dissipation air inlet 901 and the electric box 900, thereby realizing air ventilation in the electric box 900 and further effective heat dissipation. In this embodiment, the electrical box 900 is located at one end of the casing 100 in the length direction and outside the first cavity 103 and the second cavity 104.

When the air conditioner is used for refrigerating the indoor environment, if air-conditioned air enters the electric box 900 to contact with the heat exchanger 400, condensation water is easily generated in the electric box 900, and the electric control board 910 is damaged.

Specifically, the second inner cavity 104 further includes a transition cavity 105, where the transition cavity 105 and the first cavity 1041 are distributed along the length direction of the housing 100; the heat dissipation air inlet 901 is communicated with the transition cavity 105, the heat dissipation air outlet 902 is communicated with the first inner cavity 103, the heat exchange fan 500 is operated, indoor air is led into the first cavity 1041 from the shell air inlet 101 through the first inner cavity 103, then enters the electric box 900 from the heat dissipation air inlet 901 to be contacted with the radiator 920 through the transition cavity 105, and finally enters the first inner cavity 103 from the heat dissipation air outlet 902.

Since the air in the first chamber 1041 is the air not subjected to the heat exchange by the heat exchanger 400, the air entering the transition chamber 105 from the first chamber 1041 is also the air not subjected to the heat exchange by the heat exchanger 400.

By making the air entering the electrical box 900 and contacting the heat sink 920 be the air not exchanging heat with the heat exchanger 400, the condensation of the indoor air in the electrical box 900 can be avoided as much as possible, and the reliability and safety of the operation of the electric control board 910 can be increased.

The side surface of the electric box 900 provided with the heat radiation air inlet 901 is arranged close to the second inner cavity 104, and the side surface of the electric box 900 provided with the heat radiation air outlet 902 is arranged close to the first inner cavity 103. The heat dissipation air inlet 901 and the heat dissipation air outlet 902 are respectively opened at two adjacent sides of the electrical box 900, so as to increase the flow path of air in the electrical box 900, and further increase the heat dissipation effect.

The electric control board 910 is installed on the side surface of the electric box 900 where the heat dissipation air inlet 901 is provided, and the plane where the electric control board 910 is located is intersected with the side surface of the casing 100 where the casing air inlet 101 is provided.

As shown in fig. 10 and 17, the casing 100 is connected to a connection plate 180, and the connection plate 180 is disposed in the second inner cavity 104 and connected to the heat exchanger 400; the connection plate 180 is disposed to intersect the heat exchanger 400, and the connection plate 180 and the housing 100 define a transition chamber 105. The connection plate 180 is provided with a first communication port 181, and the first communication port 181 is used for communicating the first cavity 1041 with the transition cavity 105.

The connecting plate 180, the bottom plate 140, the first side plate 150 and the fixing plate 170 together define the transition cavity 105, and the electrical box 900 is connected to a side of the first side plate 150 facing away from the transition cavity 105. The first side plate 150 is provided with a second communication port 152, and the second communication port 152 is correspondingly arranged with the heat dissipation air inlet 901, so that air in the transition cavity 105 can enter the electrical box 900 from the heat dissipation air inlet 901 through the second communication port 152.

In some embodiments, the heat dissipation air inlet 901 and the heat dissipation air outlet 902 are respectively in the form of a shutter to prevent flame, water or dust impurities, etc. from entering the electrical box 900 through the heat dissipation air inlet 901 and/or the heat dissipation air outlet 902.

Because the temperature of the air after contacting the radiator 920 is different from the temperature of the air-conditioning air, if the air after contacting the radiator 920 is output indoors, the user is easy to feel two different temperatures of air, the user experience is reduced, especially when the air-conditioning air is cold air, the air after contacting the radiator 920 is hot air, and the cold air and the hot air are simultaneously contacted with the user to easily cause discomfort to the user.

In this embodiment, the air output from the heat dissipation air outlet 902 to the electrical box 900 enters the first inner cavity 103, so as to prevent the air contacted with the heat sink 920 from being output indoors, and prevent the user from contacting two different temperatures of air at the same time.

It should be noted that, the air output from the heat dissipation air outlet 902 into the first inner cavity 103 and the second inner cavity 104 of the electrical box 900 may contact with the heat exchanger 400 and exchange heat to form air-conditioning air, or may contact a part of the air with the heat exchanger 400 and exchange heat to form air-conditioning air, and another part of the air enters the transition cavity 105 through the first through hole and enters the electrical box 900 through the heat dissipation air inlet 901 to continue heat dissipation, which belongs to a common general knowledge technology in the art and is not repeated herein.

Because the electrical box 900 is disposed outside the first inner cavity 103 and the second inner cavity 104, and the electrical control board 910 in the electrical box 900 needs to be fireproof, waterproof, dustproof, and the like, in this embodiment, the enclosure 100 further includes the protection cover 120, the protection cover 120 and the first side board 150 are disposed correspondingly, an accommodating space is defined between the protection cover 120 and the first side board 150, the electrical box 900 is disposed in the accommodating space, and the protection cover 120 is utilized to protect the electrical box 900, thereby protecting the electrical control board 910.

It should be noted that, in some embodiments, other components are also mounted on a side of the second side plate 160 facing away from the second inner cavity 104, so that the second side plate 160 is correspondingly provided with the protection cover 120, and the protection cover 120 is located on two sides of the casing 100 in the length direction.

The heat dissipation principle of the electrical box 900 in the air conditioner is as follows: through the operation of the heat exchange fan 500, indoor air enters the first cavity 1041 from the casing air inlet 101 through the first inner cavity 103, then enters the electric box 900 from the heat dissipation air inlet 901 through the first communication port 181 through the transition cavity 105 and through the second communication port 152 to contact with the heat radiator 920, and the temperature of the air after passing through the heat radiator 920 is raised and enters the first inner cavity 103 from the heat dissipation air outlet 902.

The air conditioner is provided with the transition cavity 105, and the interior of the electric box 900 is communicated with the first inner cavity 103 by utilizing the transition cavity 105, so that air which does not exchange heat with the heat exchanger 400 enters the electric box 900 to be contacted with the radiator 920, thereby avoiding condensation of indoor air in the electric box 900 as much as possible, and improving the working reliability and safety of the electric control board 910; by making the air in contact with the heat sink 920 enter the first inner cavity 103, the air in contact with the heat sink 920 is prevented from being output into the room, so that discomfort to the user caused by outputting the air with two different temperatures into the room is avoided.

The air conditioner is arranged opposite to the first side plate 150 by the connecting plate 180 at intervals, so that the connecting plate 180, the first side plate 150 and the fixing plate 170 jointly define a transition cavity 105; by arranging the first communication port 181 on the connecting plate 180, the first communication port 181 is utilized to communicate the transition cavity 105 with the first cavity 1041, so that the air which does not exchange heat in the first cavity 1041 can enter the transition cavity 105 from the first communication port 181; the second communication port 152 is arranged on the first side plate 150, and the heat dissipation air inlet 901 of the electrical box 900 is correspondingly arranged with the second communication port 152, so that the second communication port 152 and the heat dissipation air inlet 901 are utilized to communicate the transition cavity 105 with the interior of the electrical box 900, and air in the transition cavity 105 enters the interior of the electrical box 900 from the heat dissipation air inlet 901 through the second communication port 152; by communicating the heat dissipation air outlet 902 of the electrical box 900 with the first inner cavity 103, the heat dissipation air outlet 902 is utilized to communicate the interior of the electrical box 900 with the first inner cavity 103, so that air contacted with the heat sink 920 can be output into the first inner cavity 103 through the heat dissipation air outlet 902, and the air contacted with the heat sink 920 is prevented from being output into a room.

As shown in fig. 17, the heat exchanger 400 is connected to a pipe, in which a refrigerant flows, and the pipe is generally located outside the first cavity 1041 and the second cavity 1042, and in this embodiment, the pipe is disposed in the transition cavity 105 to house the pipe.

It should be noted that, although the transition cavity 105 is provided with a pipeline, in consideration of the small influence of the pipeline on the air flow and the small influence on the heat dissipation effect of the electrical box 900, the air in the first inner cavity 103 may still enter the transition cavity 105 from the first through hole and enter the electrical box 900 from the heat dissipation air inlet 901 through the second through hole.

The transition cavity 105 includes a transition cavity 105 opening, the transition cavity 105 opening is disposed towards the front panel 110, because the transition cavity 105 is located in the second inner cavity 104, and the housing air outlet 102 is disposed in the second inner cavity 104, the transition cavity 105 is also communicated with the housing air outlet 102, and because the air in the first cavity 1041 which is not subjected to heat exchange also enters the transition cavity 105, the air in the transition cavity 105 which is not subjected to heat exchange is easily output to the room by the housing air outlet 102, thereby affecting the heat exchange effect of the air conditioner. Therefore, in the present embodiment, by providing the cover plate 410, the cover plate 410 is used to block the transition cavity 105 from the housing air outlet 102, so as to prevent the air in the transition cavity 105 from being output from the housing air outlet 102 into the room.
