The particular type of decontamination module 41 is not limited and one or more screens having a sterilizing function for certain specific contaminants may be configured depending on the actual use scenario. For example, the cleaning module 41 includes a dust removing mesh, a formaldehyde filtering mesh, and a plasma mesh, which are sequentially disposed in the flow direction of the air stream. The specific material of the dust removing net is not limited, and the dust removing net can play a primary role in dust removal. Besides the function of efficiently absorbing formaldehyde, the formaldehyde filter screen can also filter out other volatile organic compounds, allergens, bacteria and the like. The plasma net disinfects the air flow in the form of ion emission. As another example, the purification module 41 is a HEPA mesh (HIGH EFFICIENCY parts and effective air filter) AIR FILTER.
In some embodiments, referring to fig. 5 to 8, a second filter module 43 is disposed at the first air inlet 103, and the second filter module 43 filters indoor return air to reduce the probability of dust and other impurities entering the first air duct 101. It should be noted that, the second filter module 43 may also use a low wind resistance filter to avoid forming a larger wind resistance for the air entering the first air duct 101.
It should be noted that, in the first state, the switching duct assembly 14 may direct the airflow of the second duct to any suitable air outlet position, for example, the airflow of the second duct may be directly directed to the outside of the housing 1, that is, the airflow of the second duct may not exchange heat with the evaporator 3, and for example, the airflow of the second duct may be directed to the first duct 101 and supplied through the first air supply port 104.
For example, referring to fig. 5 to 8, a first air outlet 14a is provided on a side of the switching air duct assembly 14 facing the evaporator 3, and air flow in the switching air duct assembly 14 can flow out of the first air outlet 14a and into the evaporator 3. The air flow in the switching air duct assembly 14 can flow out of the first air outlet 14a and flow to the evaporator 3, and the switching air duct assembly 14 comprises two modes, namely, when the switching air duct assembly 14 flows in from the first air inlet 103, indoor return air entering the switching air duct assembly 14 passes out of the switching air duct assembly 14 from the first air outlet 14a and flows to the evaporator 3, and when the switching air duct assembly 14 flows in from the second air duct, air flow from the second air duct flows out of the first air outlet 14a and flows to the evaporator 3.
In this embodiment, the preset air outlet position includes a first air outlet 14a, and the first air duct 101 and the second air duct may supply air through a first air supply port 104. In this embodiment, the air flow from the second air duct flows through the evaporator 3 and is supplied through the first air supply opening 104, so that the sent air flow is close to the room temperature, and the user experience is improved.
For example, a plasma module may be disposed in the second air duct, and the plasma emitted by the plasma module can enter the first air duct 101 along with the airflow, so as to perform a sterilization and disinfection function on the first air duct 101.
Illustratively, in some embodiments, the housing 1 is provided with a second air outlet 105, the transfer duct assembly 14 is provided with a second air outlet 14b in communication with the second air outlet 105, and in the first state, the transfer duct assembly 14 is capable of selectively exhausting air from the first air outlet 14a or exhausting air from the second air outlet 14 b. That is, when the switching air duct assembly 14 is in the first state, there are two preset air outlet positions of the switching air duct assembly 14, one is the first air outlet 14a, and the other is the second air outlet 14b, so that the indoor air conditioner has two different air outlet modes. Referring to fig. 6, when the switching duct assembly 14 outputs the airflow of the second duct from the first air outlet 14a, the airflow from the second duct flows to the evaporator 3 through the first air outlet 14a and is sent out from the first air outlet 104, and at this time, the temperature of the sent airflow is close to room temperature. Referring to fig. 5, when the switching air duct assembly 14 outputs the air flow of the second air duct from the second air outlet 14b, the air flow from the second air duct is sequentially sent out through the second air outlet 14b and the second air outlet 105, and at this time, the sent air flow does not flow through the evaporator 3, and the temperature of the indoor air is not affected.
In some embodiments, a first air inlet 14c is disposed on a side of the switching air duct assembly 14 adjacent to the first air inlet 103, and a second air inlet 14d is disposed at an end of the switching air duct assembly 14 adjacent to the second air duct, where the second air inlet 14d is engaged with the end of the second air duct. The first air inlet 14c and the first air outlet 14a are located in a flow path of indoor return air from the first air inlet 103. That is, when the transfer duct assembly 14 is in the second state, the indoor return air can pass through the transfer duct assembly 14 almost along the original path to minimize the influence on the flow performance of the indoor return air.
Illustratively, the air conditioning indoor unit includes a first mode, a second mode, and a third mode.
In the first mode, referring to fig. 6, the first air outlet 14a is opened, the second air outlet 14b and the first air inlet 14c are both closed, and in this mode, the switching air duct assembly 14 is in the first state, and the air flow from the second air duct flows to the evaporator 3 through the first air outlet 14a and is sent out from the first air outlet 104.
In the second mode, referring to fig. 5, the second air outlet 14b is opened, the first air outlet 14a and the first air inlet 14c are both closed, and in this mode, the switching air duct assembly 14 is in the first state, and the air flow from the second air duct flows to the second air outlet 105 through the second air outlet 14b and is sent out from the second air outlet 105;
in the third mode, referring to fig. 7, the second air outlet 14b is closed, the first air outlet 14a and the first air inlet 14c are both opened, and in this mode, the switching air duct assembly 14 is in the second state, and the indoor return air from the first air inlet 103 enters the switching air duct assembly 14 through the first air inlet 14c and flows to the evaporator 3 through the first air outlet 14 a.
Note that, the second air inlet 14d may be kept open, or an opening/closing door may be provided at the second air inlet 14d to selectively open or close the second air inlet 14d. In the embodiment of the application, the second air inlet 14d is in the open state, so that the structure and control can be simplified.
When the switching air duct assembly 14 is in the second state, in order to facilitate the air intake of the switching air duct assembly 14 from the first air intake 103, in the third mode, the air supply mechanism is in the non-working state, that is, the air pressure in the second air duct is atmospheric pressure, and the air resistance of the switching air duct assembly 14 from the second air duct is greater than the air resistance of the air intake from the first air intake 103. For example, the wind resistance of the purifying module 41 and the wind resistance of the first filter module 42 are greater than the wind resistance of the second filter module 43, and the air is introduced into the adapting air duct assembly 14 from the first air inlet 103 under the negative pressure of the wind wheel 2, but not substantially from the second air duct.
In some embodiments, the indoor unit of the air conditioner includes a fourth mode, please refer to fig. 8, in which the second air outlet 14b is closed, the first air outlet 14a and the first air inlet 14c are both opened, i.e. the switching air duct assembly 14 is in the second state, the air supply mechanism is in the working state, and the air resistance of the switching air duct assembly 14 from the second air duct is smaller than the air resistance of the first air inlet 103. It should be noted that, when the air supply mechanism is in a working state, the air pressure in the second air duct at the air outlet side of the air supply mechanism is positive pressure, the air supply mechanism sends the air flow in the second air duct into the switching air duct assembly 14, and under the action of the wind wheel 2, the air flow entering the switching air duct assembly 14 will not be blown out from the first air inlet 14c, but will only be blown out from the first air outlet 14 a.
In some embodiments, referring to fig. 5 to 8, the housing 1 includes a chassis 11, a face frame assembly 12, and a panel, the chassis 11 and the face frame assembly 12 are fastened to each other to form an installation space, the chassis 11 is configured with a volute 111, the wind wheel 2 is rotatably disposed in the volute 111, the evaporator 3 is covered on an air inlet side of the volute 111, and an air outlet end of the volute 111 is formed as a first air supply port 104. The chassis 11 is used as a structural stress member of the air conditioner indoor unit, for example, the air conditioner indoor unit is hung on a wall body through the chassis 11, and the chassis 11 bears the weight of the parts such as the face frame assembly 12, the panel, the wind wheel 2, the air supply mechanism, the electric control box and the like.
The first air inlet 103 is disposed on the top side of the face frame assembly 12, the switching air duct assembly 14 is disposed between the front side of the evaporator 3 and the rear side of the face frame assembly 12, and in the second state, part of the indoor return air from the first air inlet 103 passes through the switching air duct assembly 14 from top to bottom. In this embodiment, the switching air duct assembly 14 is disposed at the front side of the evaporator 3, and makes full use of the space at the front side of the evaporator 3, so that the air flow of the second air duct is conveniently guided to the evaporator 3 without changing the structural design of the first air duct 101.
In some embodiments, referring to fig. 5 to 8, the evaporator 3 includes a rear vapor 31, a middle vapor 32, and a front vapor 33 connected in sequence. Specifically, the rear steam 31 is disposed obliquely upward, the middle steam 32 is disposed obliquely downward, and the front steam 33 is connected to the bottom end of the middle steam 32 along the direction from the rear to the front of the air conditioning indoor unit. The rear steam 31, the middle steam 32 and the front steam 33 are formed in an inverted V-shaped structure and are inverted over the scroll case 111.
The transfer duct assembly 14 abuts against the front side of the middle steam 32, and indoor return air passing through the transfer duct assembly 14 can flow to the middle steam 32 and the front steam 33, that is, the transfer duct assembly 14 does not affect the heat exchange efficiency of the middle steam 32 and the front steam 33 on indoor return air. Because the middle steam 32 is arranged obliquely downwards, the space between the middle steam 32 and the face frame assembly 12 is in a form of big end down, the transfer air duct assembly 14 is wedged into the space between the middle steam 32 and the face frame assembly 12, and the middle steam 32 can play a certain supporting role on the transfer air duct assembly 14, that is, can bear the weight of the transfer air duct assembly 14 by means of the middle steam 32.
It will be appreciated that the switched air duct assembly 14 may be connected to the face frame assembly 12, or the switched air duct assembly 14 may be connected to the evaporator 3, or both the face frame assembly 12 and the evaporator 3 may be connected to the switched air duct assembly 14.
Illustratively, referring to fig. 4, the evaporator 3 is provided with refrigerant pipe ends 3a at opposite ends in the length direction, and the transfer duct assembly 14 is detachably connected to the refrigerant pipe ends 3a, so that the transfer duct assembly 14 can be installed by fully utilizing the existing structure of the evaporator 3.
The specific connection manner of the transfer duct assembly 14 and the refrigerant tube end 3a is not limited as long as it is convenient to install and detach. As an example, referring to fig. 10 to 12, an elastic buckle 143 is disposed on a side of the adapting duct assembly 14 facing the evaporator 3, the elastic buckle 143 has a clamping groove 143a and an opening 143b, and the opening 143b is restored to be spread by the refrigerant pipe end 3a during the process of clamping the refrigerant pipe end 3a into the clamping groove 143 a. Specifically, during the assembly process, the clamping groove 143a of the switching air duct assembly 14 is aligned to the refrigerant pipe end 3a and is buckled on the refrigerant pipe end 3a, during the process that the refrigerant pipe end 3a is clamped into the clamping groove 143a, the refrigerant pipe end 3a forces the elastic buckle 143 to elastically deform and enlarge the opening 143b, when the refrigerant pipe end 3a is clamped into the clamping groove 143a, the elastic buckle 143 partially or completely recovers the elastic deformation, and the opening 143b is contracted to limit the refrigerant pipe end 3a in the clamping groove 143 a. When the transfer air duct assembly 14 needs to be disassembled, only the transfer air duct assembly 14 needs to be pulled by force, and the elastic buckle 143 is separated from the refrigerant pipe end 3 a.

Referring to fig. 11, a first air outlet 14a is provided at the rear side of the air duct body 141, a first air inlet 14c is provided at the top side, a second air outlet 14b is provided at the front side, the second air outlet 14b is aligned with the second air outlet 105, and the valve assembly 142 can move relative to the air duct body 141 to selectively close the first air inlet 14c, the first air outlet 14a or the second air outlet 14b. In this embodiment, the duct body 141 remains stationary and the direction of airflow is switched by movement of the valve assembly 142.
The specific configuration of the duct body 141 is not limited, and in some embodiments, referring to fig. 10 and 11, the duct body 141 includes a top frame plate 1413, a first frame plate 1411 abutting against the evaporator 3, and a second frame plate 1412 disposed at a front side of the first frame plate 1411, and a lower end of the first frame plate 1411 is connected to a lower end of the second frame plate 1412. The first frame plate 1411, the second frame plate 1412, and the top frame plate 1413 generally form a triangular structure. Wherein the gaps on the first frame plate 1411 form the first air outlet 14a, the gaps on the second frame plate 1412 form the second air outlet 14b, and the gaps on the top frame plate 1413 form the first air inlet 14c.
The valve assembly 142 includes a first valve plate 1421 and a second valve plate 1422, wherein a lower end of the first valve plate 1421 is rotatably connected to a connection of the first frame plate 1411 and the second frame plate 1412, and the first valve plate 1421 can be selectively stacked on an inner surface of the first frame plate 1411 or on an inner surface of the second frame plate 1412, that is, opening and closing of the first air outlet 14a and the second air outlet 14b are controlled by the first valve plate 1421, so that at most one of the first air outlet 14a or the second air outlet 14b is closed at the same time, and not both are simultaneously in a closed state. The second valve plate 1422 is disposed at the first air inlet 14c to selectively open or close the first air inlet 14c.
