The first accommodating space 121 and the second accommodating space 122 are symmetrically disposed with respect to the air outlet 20, and the first accommodating space 121 is taken as an example to describe specific configurations of the fan, the evaporator, and the like.
The first air inlet 30 is formed at an upper portion of the first accommodating space 121, and is used for guiding normal temperature air that does not undergo heat exchange outside the jet type indoor unit 100 of the air conditioner into the first accommodating space 121. First air intake 30 is close to one side of first accommodation space 121 and is formed with first filter screen 31 and is used for supporting first filter screen support 32 and first filter screen support handle 33 of first filter screen 31, and first filter screen support 32 is connected with first filter screen support handle 33, first filter screen 31 is used for filtering the air that gets into by first air intake 30. A first fan 34 and a first evaporator set 35 are further disposed between the first filter screen 31 and the air outlet 20, the first fan 34 is preferably a cross-flow fan, which can reduce the working noise, and the first fan 34 is integrally cylindrical, and the central axis of the first fan 34 is parallel to the upper edge of the air outlet 20, i.e. the first fan 34 is disposed horizontally, on one hand, the overall volume of the jet type air conditioning indoor unit 100 can be reduced, and on the other hand, the air outlet surface of the first fan 34 can be aligned to the air outlet 20, so as to increase the air volume and the air speed entering the air outlet 20. The first evaporator group 35 is located between the first fan 34 and the first filter screen 31, the refrigerant can flow to the first evaporator group 35 through the copper pipe from the lower position of the rear shell 12, here, the first evaporator group 35 is composed of two evaporators with a certain included angle, so that the first fan 34 can be wrapped well, the heat exchange area is increased, and the refrigerating and heating capacity is improved. A first air outlet duct 36 is formed between the first fan 34 and an upper region of the air outlet 20, and the first air outlet duct 36 is used for transmitting the air after heat exchange to the air outlet 20.
A second air inlet 40 is formed at a lower portion of the second accommodating space 122, and a second filter screen 41, a second filter screen bracket 42, a second filter screen bracket handle 43, a second fan 44 and a second evaporator set 45 are further accommodated between the second air inlet 40 and a lower edge of the air outlet 20, and specific descriptions of these components may refer to descriptions of corresponding components in the first accommodating space 121, which are not repeated herein. A second air outlet duct 46 is formed between the second fan 44 and a lower region of the air outlet 20, and the second air outlet duct 46 is used for transmitting the air after heat exchange to the air outlet 20.
In the present embodiment, while the first air duct 36 and the second air duct 46 blow out the heat-exchange air to the air outlet 20, the non-heat-exchange air (normal temperature air) that can suck part of the external non-heat-exchange air participates in the final air outlet of the air conditioner, such mixed air is soft, and the user can feel more comfortable when blowing the mixed air to the user, thereby improving the user comfort experience effect. And moreover, partial external non-heat-exchanged air is sucked into the final air outlet of the air conditioner under the action of negative pressure generated by the heat-exchanged air, so that the integral air inlet volume of the air conditioner is increased, the flow of indoor air is accelerated, and the integral uniformity of the indoor air is further improved. In other words, when the cold (hot) air after heat exchange is injected into the ambient air at a high speed, a discontinuous surface with different speed exists between the cold (hot) air and the ambient static air, the cold (hot) air is disturbed and loses stability to generate vortex, the ambient air is sucked in to be jetted, the sucked air flows forwards along with the original cold (hot) air jet flow, the jet flow area of the cold (hot) air after entrainment and mixing is continuously enlarged, the flow speed is continuously reduced, the flow is continuously increased, the most direct effect is that the wind is softer and more natural, the cold but not cold when being blown to the human body, and the problem of air conditioning diseases is solved.
In addition, the first fan 34 and the second fan 44 are directly arranged on the upper side and the lower side of the air outlet 20, the lengths of the first air outlet channel 36 and the second air outlet channel 46 are shortened, and the distance from the heat exchange air generated by the first fan 34 and the second fan 44 to the air outlet 20 is shorter, so that the attenuation of the transmission speed of the heat exchange air is less, the heat exchange air can still be transmitted to the air outlet 20 at a higher speed, the drainage effect on the normal temperature air is better, and the whole air outlet efficiency of the air conditioner is high. Moreover, since the first fan 34 and the second fan 44 are directly disposed on the upper side and the lower side of the air outlet 20, and the air outlet surfaces of the first fan 34 and the second fan 44 are directly aligned with the air outlet 20, the first air outlet duct 36 and the second air outlet duct 46 do not need to be disposed in a bending or bending structure, and the structure is simple and easy to mold.
As shown in fig. 3 and 4, the jet type air conditioning indoor unit 100 further includes an opening and closing assembly 50 for opening and closing the first air outlet duct 36 and the second air outlet duct 46.

In the present embodiment, while the first fan 34 and the second fan 44 blow out the heat-exchange air to the air outlet 20, the non-heat-exchange air (normal temperature air) that can suck part of the external non-heat-exchange air participates in the final air outlet of the air conditioner, such mixed air is softer, and the user feels more comfortable when blowing on the body, thereby improving the user comfort experience effect. And moreover, partial external non-heat-exchanged air is sucked into the final air outlet of the air conditioner under the action of negative pressure generated by the heat-exchanged air, so that the integral air inlet volume of the air conditioner is increased, the flow of indoor air is accelerated, and the integral uniformity of the indoor air is further improved. In other words, when the cold (hot) air after heat exchange is injected into the ambient air at a high speed, a discontinuous surface with different speed exists between the cold (hot) air and the ambient static air, the cold (hot) air is disturbed and loses stability to generate vortex, the ambient air is sucked in to be jetted, the sucked air flows forwards along with the original cold (hot) air jet flow, the jet flow area of the cold (hot) air after entrainment and mixing is continuously enlarged, the flow speed is continuously reduced, the flow is continuously increased, the most direct effect is that the wind is softer and more natural, the cold but not cold when being blown to the human body, and the problem of air conditioning diseases is solved.
In addition, the first fan 34 and the second fan 44 are directly disposed at the upper side and the lower side of the air outlet 20, the lengths of the first air outlet channel 36 between the first fan 34 and the air outlet 20 and the second air outlet channel 46 between the second fan 44 and the air outlet 20 are shortened, and the distance from the heat exchange air generated by the first fan 34 and the second fan 44 to the air outlet 20 is shorter, so that the transmission speed attenuation of the heat exchange air is less, the heat exchange air can be transmitted to the air outlet 20 at a higher speed, the flow guiding effect on the normal temperature air is better, and the overall air outlet efficiency of the air conditioner is high. Moreover, since the first fan 34 and the second fan 44 are directly disposed on the upper and lower sides of the air outlet 20, and the air outlet surfaces of the first fan 34 and the second fan 44 are directly aligned with the air outlet 20, the first air outlet duct 36 and the second air outlet duct 46 do not need to be disposed in a bending or bending structure, and the structure is simple and easy to mold.
In this embodiment, the step of "guiding the heat-exchange air generated by the first fan 34 and/or the second fan 44 to the air outlet 20" specifically includes:
the outlet baffle 521 moves a first distance relative to the outlet liner 51 to open a first opening 511 and a second opening 512 respectively located at the upper and lower sides of the outlet liner 51, the outlet liner 51 is located at the edge area of the outlet 20, wherein the first distance is substantially equal to the maximum width of the edge of the outlet liner 51;
the first air deflector 522 and/or the second air deflector 523 both rotate by a first angle, so that the heat-exchanged air is transmitted to the air outlet 20 through the corresponding first opening 511 and/or the second opening 512, and the heat-exchanged air is mixed with the normal-temperature air at the air outlet 20.
