Referring to fig. 1 to 7, an embodiment of the present disclosure provides an indoor unit of an air conditioner, including a casing 10, a heat exchange assembly 20, and a double-through-flow air duct assembly, where the casing 10 is provided with an air inlet 101; the heat exchange assembly 20 includes a first heat exchange element 201 and a second heat exchange element 202 disposed opposite each other; the double through-flow air duct component is arranged in the shell 10 and at least defines three air ducts which are arranged side by side along the transverse direction; the first heat exchange element 201 and the second heat exchange element 202 are respectively and correspondingly arranged on two air channels on two sides, and the air channel in the middle is communicated with the adjacent air channels, so that the airflows of the adjacent air channels are mixed, and the temperature of the air outlet is uniform.

By adopting the air conditioner indoor unit provided by the embodiment of the disclosure, the first heat exchange element 201 and the second heat exchange element 202 are respectively and correspondingly arranged on the two outermost air channels formed by the double-through-flow air channel assembly, the air flow after heat exchange of the first heat exchange element 201 and the second heat exchange element 202 is blown out through the corresponding air channels, and is communicated with the adjacent air channels through the middle air channel, and the air flow after heat exchange flows and mixes with the middle air channel, so that the air outlet temperature of the corresponding two air channels is different due to different heat exchange efficiency of the heat exchange elements, the air outlet temperature between the adjacent air channels is similar through the middle air channels, the purpose of uniform air outlet temperature is achieved, and the user experience is improved.

The indoor unit of the air conditioner can be a cabinet air conditioner, the front side of the casing 10 is provided with an air outlet 102, the rear side is provided with an air inlet 101, and the heat exchange assembly 20 is arranged close to the air inlet 101. Optionally, the first heat exchange element 201 is a heat exchanger and the second heat exchange element 202 is a heat exchanger. After the air flow is sucked through the air inlet 101 and flows through the heat exchange assembly 20 to exchange heat with the heat exchange assembly 20, the temperature is increased or reduced, so that the purpose of heating or refrigerating is realized.

The first heat exchanging element 201 and the second heat exchanging element 202 are disposed opposite to each other and along the direction of the air inlet grille 103, so that the air flow entering from the air inlet grille 103 exchanges heat with the heat exchanger. For example, the first heat exchanging element 201 and/or the second heat exchanging element 202 may have an arcuate configuration to match the orientation of the air inlet grille 103.

The double-through-flow air duct assembly is located at the air outlet side of the heat exchange assembly 20, and defines three air ducts arranged side by side in the transverse direction, wherein the air inlet area, the air outlet area and the ventilation area of the three air ducts can be partially identical. In particular, the two air channels on two sides have the same structure. Therefore, the indoor unit of the air conditioner is of a symmetrical structure, is convenient to process and is more attractive.

The first heat exchange element 201 and the second heat exchange element 202 are respectively corresponding to two air channels on two sides, and air flows subjected to heat exchange by the first heat exchange element 201 and the second heat exchange element 202 are respectively blown out from the corresponding air channels. In practical application, the power of the first heat exchange element 201 and the second heat exchange element 202 is generally the same, but after a certain period of use, the first heat exchange element 201 and the second heat exchange element 202 have conditions of refrigerant leakage, surface area ash, impurity shielding, and the like, so that the heat exchange efficiency of the first heat exchange element 201 and the heat exchange efficiency of the second heat exchange element 202 are different, and the temperature of the air flow subjected to heat exchange by the first heat exchange element 201 and the second heat exchange element 202 are different, so that the temperature of the air flow blown by the two air channels are different, and the experience of a user is affected. The air channels in the middle are communicated with the adjacent air channels, so that air flows in the air channels at least at two sides can flow to the middle air channel, mixed air flows out from the middle air channel, and the difference of the air outlet temperatures of the air channels at two sides can be reduced, namely, the temperature of the air flows blown out by the three air channels is stably transited so that the air outlet temperature of the air outlet 102 is uniform.

Optionally, the dual through-flow air duct assembly includes a volute 301, a first volute tongue 302, and a second volute tongue 303. The volute 301 includes opposed first and second side walls 3011, 3012, the first and second side walls 3011, 3012 defining a first air path 304; the first volute tongue 302 and the first side wall 3011 of the volute 301 define a second air channel 305; the second volute tongue 303 and the second side wall 3012 of the volute 301 define a third air channel 306; the second air duct 305 and the third air duct 306 are located at two sides of the first air duct 304, and the side wall of the volute 301 is configured with a plurality of ventilation holes to communicate the first air duct 304 with the second air duct 305 and the first air duct 304 with the third air duct 306.

The first heat exchange element 201 is disposed at the air inlet end of the second air duct 305, and after a part of air flow exchanges heat with the first heat exchange element 201, the air flow enters the second air duct 305. Similarly, the second heat exchange element 202 is disposed at the air inlet end of the third air duct 306, and part of the airflow enters the third air duct 306 after exchanging heat with the second heat exchange element 202. The airflows in the second air duct 305 and the third air duct 306 flow into the first air duct 304 through the ventilation holes on the side wall of the volute 301 to be mixed, so that the uniformity of the airflows is improved.

The first side wall 3011 and the second side wall 3012 of the volute 301 are identical in structure and symmetrically arranged, and the first volute tongue 302 and the second volute tongue 303 are identical in structure and symmetrically arranged, so that the second air duct 305 and the third air duct 306 are symmetrically arranged relative to the first air duct 304, and under the condition that the air conditioner indoor unit works, the difference of gas flow in the second air duct 305 and the third air duct 306 is reduced, the pressure in the second air duct 305 and the third air duct 306 is kept, the gas flow flowing into the first air duct 304 from the second air duct 305 and the third air duct 306 is further ensured, the gas temperature of the two air ducts can be averaged, the stability of the air conditioner indoor unit in the working process can be improved, and shaking is avoided.

Optionally, a plurality of vent holes in the sidewall configuration of the volute 301 are preferentially ordered. In this way, turbulence is avoided when the air flows.

Optionally, the aperture of the vent hole gradually increases from the air inlet end to the air outlet end along the blowing direction of the air flow in the air channel. In this way, on one hand, the stability of the airflow in the flowing process can be improved, on the other hand, the flow rate of the airflow in the second air duct 305 and the third air duct 306, which is close to the air outlet end, can be improved by matching with the cross-flow fan, and the uniformity of the airflow at the air outlet 102 is further improved.

The first volute tongue 302 and the second volute tongue 303 are respectively and rotatably connected with the swinging blade 310 so as to adjust the air outlet direction of the corresponding air duct.

Optionally, the dual through-flow air duct assembly further includes a second through-flow fan 308 and a third through-flow fan 309; the second cross-flow fan 308 is vertically arranged in the second air duct 305; the third cross flow fan 309 is vertically disposed in the third air duct 306 and symmetrically disposed with the second cross flow fan 308. The second cross flow fan 308 drives the airflow in the second air channel 305, and the third cross flow fan 309 drives the airflow in the third air channel 306. The second cross flow fan 308 and the third cross flow fan 309 are symmetrically arranged, which is helpful for improving the stability of the indoor unit of the air conditioner.

In the case that there is no cross flow fan in the first air duct 304 of the indoor unit of the air conditioner, the air flow in the first air duct 304 is sucked and blown out passively by the suction force of the second cross flow fan 308 and the third cross flow fan 309 and acts on the first air duct 304 through the ventilation holes on the side wall of the volute 301.

Optionally, the air intake area of the first air duct 304 is smaller than the air intake area of the second air duct 305 and smaller than the air intake area of the third air duct 306. In this way, the flow rate of the gas exchanging heat with the first heat exchanging element 201 and the second heat exchanging element 202 can be ensured, thereby ensuring the heating or cooling effect of the air conditioner.

Optionally, the ventilation area of the first air duct 304 is smaller than the ventilation area of the second air duct 305 and smaller than the ventilation area of the third air duct 306. In this way, on the one hand, the air output of the second air duct 305 and the third air duct 306 can be ensured, and the phenomenon that excessive air flows from the second air duct 305 and the third air duct 306 to the first air duct 304 to cause larger fluctuation of air flow and turbulent flow is avoided, so that the stability of the air output is affected. Optionally, the air inlet area of the second air duct 305 is equal to the air inlet area of the third air duct 306.

It should be noted that: the "ventilation area" referred to herein refers to the ventilation area of the cross section of the duct throughout.

Optionally, an end of the first heat exchange element 201 opposite to the second heat exchange element 202 defines an accommodating space 203, and the air conditioning indoor unit further includes: the heating element 40 is arranged in the accommodating space 203 in a vertical extending manner and corresponds to the first air duct 304; under heating conditions, part of air entering the casing 10 through the air inlet 101 is heated by the heating element 40 and blown out through the first air duct 304.

The first heat exchange element 201 and the second heat exchange element 202 are symmetrically disposed, and a certain distance is reserved between two opposite ends to define an accommodating space 203, and the heating element 40 is disposed in the accommodating space 203 along a vertical extension. Thus, the air flow entering the housing 10 from the air inlet 101 flows partly through the first heat exchange element 201, partly through the heating element 40 and partly through the second heat exchange element 202. The air flowing through the heating element 40 flows into the first air duct 304 corresponding to the heating element 40, and is blown out through the first air duct 304.

Under heating working conditions, the heating element 40 works, part of air flow entering the shell 10 from the air inlet 101 directly flows to the heating element 40, and the air flow is not blocked, so that the flow passing through the heating element 40 is more, the heating element 40 can exert high heating performance, and the heating effect of the air conditioner can be improved.

Under the refrigeration working condition, the heating element 40 does not work, the air flows through the heating element 40 and enters the first air channel 304, the air flows in the adjacent air channels flow into the first air channel 304 and are mixed with the air flows in the first air channel 304, so that the cold air blown out from the first air channel 304 is relatively soft, and the user experience is improved.

In practical application, the heating element 40 is detachably connected to the casing 10 and electrically connected to an electronic control module of the indoor unit of the air conditioner, so as to control the operation of the heating element 40 through the electronic control module.

Alternatively, the heating element 40 may be a PTC heater.

Optionally, the volute 301 has a U-shaped structure, and the volute 301 further includes: an open end 3014 facing the heating element 40 and the open area covering the heating element 40; and a closed end 3015 configured with a plurality of air outlet holes 3018 for blowing air flow of the first air duct 304 out of the air outlet holes 3018.

The open end 3014 of the volute 301 is oriented toward the heating element 40 such that airflow through the heating element 40 flows into a first air duct 304 defined by the volute 301. The opening area of the opening end 3014 may be understood as an air inlet area of the first air duct 304. The open area of open end 3014 covers heating element 40. In this way, the air flow through the heating element 40 may flow entirely into the first air duct 304.

In practical applications, the heating element 40 may be disposed within the opening of the open end 3014, or may be disposed outside the opening of the open end 3014, so long as the open area of the open end 3014 is ensured to cover the heating element 40.

The closed end 3015 is configured with a plurality of air outlet holes 3018, so that the air flowing into the first air duct 304 from the open end 3014 can be blown out through the air outlet holes 3018, thereby realizing the circulation of the air in the first air duct 304.

Alternatively, the two edges of the open end 3014 are respectively bent and extended outwards to form a lap portion 3017, and are respectively connected to the first heat exchange element 201 and the second heat exchange element 202, so that the air flow flowing through the accommodating space 203 flows into the first air duct 304.

The two edges of the open end 3014 are the edge of the first side wall 3011 of the scroll 301 and the edge of the second side wall 3012 of the scroll 301, respectively, and the two edges are bent and extended outwardly to form the overlapping portion 3017, where the overlapping portions 3017 defining the two edges are the first overlapping portion 3017 and the second overlapping portion 3017, respectively, for convenience of description and distinction. Wherein the first overlap 3017 is connected to the first heat exchange element 201 and the second overlap 3017 is connected to the second heat exchange element 202. In this way, the two overlapping portions 3017 are trumpet-shaped so that the air flow flowing in from the accommodation space 203 entirely flows into the open end 3014 of the scroll casing 301, i.e., into the first air passage 304.

In addition, the connection of the first overlap 3017 to the first heat exchange element 201 and the connection of the second overlap 3017 to the second heat exchange element 202 also help to improve the stability of the volute 301. Alternatively, the first overlap 3017 is connected to an edge of the first heat exchange element 201 and the second overlap 3017 is connected to an edge of the second heat exchange element 202. In this way, the overlap 3017 is prevented from affecting the airflow through the heat exchange element, and the overlap 3017 is prevented from obstructing the airflow.

Optionally, the closed end 3015 of the volute 301 protrudes from the plane of the air outlet 102 of the second air duct 305 and/or the plane of the air outlet 102 of the third air duct 306, so that the air flow blown out from the first air duct 304 is not regulated by the swing blade 310.

Here, "connected" is detachably connected or abutted.

Optionally, the first side wall 3011 of the volute 301 is bent at a position opposite to the first volute tongue 302 to form a concave space 3016 matched with the swing vane 310, so that the swing vane 310 acts to adjust the airflow of the second air duct 305; and/or, the second side wall 3012 of the volute 301 is bent at a position opposite to the second volute tongue 303 to form a concave space 3016 matched with the swing vane 310, so that the swing vane 310 acts to adjust the airflow of the third air duct 306.

The first side wall 3011 of the volute 301 is bent towards the first air channel 304 at a position opposite to the first volute tongue 302, so that a concave space 3016 is formed, and a space which accommodates the swing blade 310 and matches with the swing blade 310 is defined at the bent position of the first volute tongue 302 and the first side wall 3011, so that the swing blade 310 swings, and the air flow of the second air channel 305 is regulated.

In addition, the first side wall 3011 is bent in the direction of the first air duct 304, and the air outlet 102 of the second air duct 305 is directed in the opposite direction, so that the air outlet range of the air conditioner can be widened. Similarly, the second side wall 3012 bends towards the first air duct 304, and the air outlet 102 of the third air duct 306 faces towards the opposite direction, so that the air outlet range of the air conditioner can be enlarged.

Optionally, the indoor unit of the air conditioner further includes a first through-flow fan 307, where the first through-flow fan 307 is disposed in the casing 10 and located in the middle air duct to drive the airflow in the air duct to flow.

In the case that the first through-flow fan 307 is disposed in the middle air duct, that is, the first air duct 304, the first through-flow fan 307 actively sucks and blows out the first air duct 304, which helps to accelerate the airflow velocity in the first air duct 304.

Optionally, the first through-flow fan 307 is disposed vertically in the first air duct 304. The first through-flow fan 307 is preferentially disposed near the air outlet end of the first air duct 304. In this way, the first through-flow fan 307 can suck the air outside the indoor unit of the air conditioner into the first air duct 304, and can suck the air flow of the adjacent air duct into the first air duct 304 to mix with the air flow in the first air duct 304, so as to achieve the purpose of uniform air outlet temperature of the air outlet 102.

Optionally, the dual through-flow air duct assembly further includes a second through-flow fan 308 and a third through-flow fan 309; the second cross-flow fan 308 is vertically arranged in the second air duct 305; the third cross flow fan 309 is vertically arranged in the third air duct 306 and is symmetrically arranged with the second cross flow fan 308; wherein the second through-flow fan 308 and/or the third through-flow fan 309 are located on the air inlet side of the first through-flow fan 307, so that the air streams of the adjacent air channels of the first through-flow fan 307 are sucked into the first air channel 304 and mixed.

The second through-flow fan 308 is located on the air inlet side of the first through-flow fan 307, which helps the second through-flow fan 308 and the first through-flow fan 307 cooperate with each other, that is, the second through-flow fan 308 blows out the air flow, and the first through-flow fan 307 sucks in the air flow, so that the air flow in the second air duct 305 flows smoothly into the first air duct 304, so as to prevent turbulence.

Similarly, the third through-flow fan 309 is located on the air inlet side of the first through-flow fan 307, which is helpful for the third through-flow fan 309 and the first through-flow fan 307 to cooperate with each other, i.e. the third through-flow fan 309 blows out the air flow, and the first through-flow fan 307 sucks in the air flow, so that the air flow in the third air duct 306 flows smoothly into the first air duct 304, so as to prevent turbulence.

Optionally, the first through-flow fan 307 is vertically disposed, and a distance from an axis to the closed end 3015 is smaller than a distance from the axis to the open end 3014, so as to extend a length of an air duct on an air inlet side of the first through-flow fan 307, so that air flows in adjacent air ducts flow into the first air duct 304 and are blown out through the first through-flow fan 307.

The "the distance from the axis of the first flow fan 307 to the closed end 3015 is smaller than the distance from the axis to the open end 3014" may be understood herein as: the first through-flow fan 307 is disposed proximate the closed end 3015. In this way, the length of the air duct on the air intake side of the first flow fan 307 can be extended so that the ventilation hole of the side wall of the volute 301 is located on the air intake side of the first flow fan 307 as much as possible. When the first through-flow fan 307 works, the air flow of the adjacent air channels can be sucked into the first air channel 304 through the vent holes to be mixed with the air flow in the first air channel 304 and blown out; which helps to enhance the mixing of the air flow in the first duct 304 with the air flow in the adjacent duct.

Optionally, the cross-sectional area of the first cross-flow fan 307 is smaller than the cross-sectional area of the second cross-flow fan 308 and/or the cross-sectional area of the third cross-flow fan 309.

It can be understood that: at the same time, the airflow rate of the first cross flow fan 307 is smaller than the airflow rate of the second cross flow fan 308 and/or is also smaller than the airflow rate of the third cross flow fan 309. In this way, the air conditioning indoor unit is also an air outlet duct mainly comprising the second duct 305 and the third duct 306. The air flows in the second air duct 305 and the third air duct 306 of the mixed part of the first air duct 304 play a role in transition of the air outlet temperature of the second air duct 305 and the third air duct 306, so that the air outlet temperature of the air outlet 102 is uniform.

In addition, under the heating condition, the heating element 40 in the first air duct 304 works to heat the air flowing in the first air duct 304, so that the temperature of the air flowing in the first air duct 304 is increased, and the heating effect of the air conditioner is improved.

The first flow fan 307 is located at a bend in the side wall of the scroll 301 where the recessed space 3016 is configured such that the radial dimension of the first flow fan 307 matches the width dimension of the first air duct 304 therein. In this way, the air flows in the first air duct 304 all flow through the first through-flow fan 307 and blow out under the suction effect of the first through-flow fan 307.

The distance from the bending position of the first side wall 3011 with the concave space 3016 to the bending position of the second side wall 3012 with the concave space 3016 is smaller, so that a cross-flow fan with smaller ventilation area can be configured, and a cross-flow fan with lower power and energy consumption can be selected, thereby reducing the overall energy consumption of the air conditioner.

Optionally, the germicidal lamp 501 and the bipolar ion generator 502 are disposed at the top and bottom of the first air duct 304 opposite to each other, so that the active area of the germicidal lamp 501 and the bipolar ion generator 502 covers the air inlet area of the air inlet end of the first air duct 304.

The germicidal lamp 501 is disposed at the top of the first air duct 304, so that the light emitted from the germicidal lamp 501 irradiates downward. The bipolar ion generator 502 is disposed at the bottom of the first air duct 304 and is preferably located directly under the germicidal lamp 501, so that the bipolar ion generator and the germicidal lamp 501 can cooperate with each other to make the sterilization area of the two cover the air inlet area of the air inlet end of the first air duct 304, thereby ensuring the sterilization effect.

Optionally, the sterilization assembly 50 is located on the air intake side of the first through-flow fan 307, so that the air flow sterilized by the sterilization assembly 50 is blown out through the first through-flow fan 307.

The sterilization assembly 50 is located on the air inlet side of the first through-flow fan 307, and it is understood that the sterilization assembly 50 may be disposed not only on the air inlet end of the first air duct 304, but also near the air inlet side of the first through-flow fan 307. In this way, the air flow entering the first air duct 304 from the adjacent air duct is sterilized by the sterilizing component 50 and then blown out by the first through-flow fan 307, so as to ensure the sterilizing effect of the air conditioner.

It should be noted that, the sterilization assembly 50 only works for the air flow blown out by the first air duct 304, and is not equivalent to the sterilization mode of the air conditioner. The sterilization assembly 50 may operate not only when the sterilization mode of the air conditioner is operated, but also in modes of heating, cooling, purifying, dehumidifying, etc. The primary purpose of the sterilization assembly 50 is to minimize the bacteria and viruses carried by the air conditioning's daily blown air stream.
