Embodiments of the present application provide an air conditioner indoor unit and an air conditioner, which will be described in detail below.

First, referring to FIG. 1, FIG. 1 shows a schematic cross-sectional view of an air-conditioning indoor unit in an embodiment of the present application, wherein the air-conditioning indoor unit includes:

base 10;

The fresh air duct 20 extending along the length direction of the base 10, the fresh air module 30 and the electric control module 40 installed on the base;

On the cross section of the base 10 perpendicular to its length direction, a fresh air module installation area 110, an electric control module installation area 120 and a fresh air duct area 130 are formed;

Wherein, the boundary line 50 between the fresh air module installation area 110 and the electric control module installation area 120 is a straight line or a curve extending from the fresh air duct area 130 .

Specifically, the base 10 is used as an assembly base of the indoor unit of the fresh air air conditioner, and components of the indoor unit of the air conditioner such as the fresh air module 30 , the electronic control module 40 , and the evaporator can be installed. Wherein, the fresh air module 30 and the electric control module 40 are located at the same end on the base 10, for example, the fresh air module 30 and the electric control module 40 are arranged on the right end or the left end of the base 10, and the wind wheel 80 and the evaporator are installed along the length direction of the base 10 In the remaining space on the base 10, the length of the evaporator is long and there is enough surface for heat exchange.

It is worth noting that this application does not specifically limit the shape of the base 10, but for ease of understanding, the length direction of the base 10 refers to the direction of the longest edge of the cubic space occupied by the base. Correspondingly, the width direction of the base 10 refers to the The length direction of the base 10 is perpendicular to the direction of the horizontal plane, and the height direction of the base 10 refers to the direction perpendicular to the length direction of the base 10 and located on the vertical plane.

One end of the fresh air pipe 20 is connected to the fresh air module 30 , and the other end is extended to the outside, so that the fresh air module 30 communicates with the outside world to introduce outside air and deliver it to the room. Generally, as shown in Figure 1, the fresh air pipe 20 is located on the back side of the base 10, and the axis of the fresh air pipe 20 is along the length direction of the base 10, so that the fresh air pipe 20 can be hidden on the back side of the base 10 so that the new air The air duct 20 takes up less space. Exemplarily, the fresh air pipe 20 may be a plastic pipe or a metal pipe.

The fresh air module 30 is used to introduce outdoor fresh air through the fresh air pipe 20, wherein the fresh air module 30 is located in the indoor part of the fresh air air conditioner, such as a wall-mounted indoor unit, and the fresh air pipe 20 communicates with the external air conditioner through the wall. When the fresh air module 30 is working, for example, when the corresponding fan in the fresh air module 30 starts up, fresh air is introduced from the outside into the fan volute of the fresh air module 30, and then blows into the room through the air outlet 311 to refresh the indoor air.

In some embodiments of the present application, the axis of the fresh air module 30 is parallel to the length direction of the base 10. Since the length of the fresh air module along the axial direction is small, the axis of the fresh air module 30 is parallel to the length direction of the base 10 to install the fresh air module. 30 can further reduce the length of the air conditioner indoor unit. It can be understood that the fresh air module 30 humidifies other components such as a humidifying device to realize functions such as fresh air humidification.

The electronic control module 40 is used to control the startup and shutdown of the fresh air module 30. It can be understood that the electronic control module 40 can also control the startup and shutdown of other electrical devices, such as controlling the startup of the motor of the wind deflector 70 to realize the wind sweeping function, and for example The rotation of the wind wheel 80 is controlled to blow cold/warm wind into the room. Wherein, the electric control module 40 may include a circuit board and a square electric control box, and the circuit board is installed and sealed in the electric control box, so as to prevent the circuit board from contacting with the outside to generate condensation and short circuit.

On the cross section of the base 10 perpendicular to its length direction, a fresh air module installation area 110, an electric control module installation area 120 and a fresh air duct area 130 are formed, because the fresh air module installation area is set on the same cross section of the base 10 perpendicular to its length direction 110, the electric control module installation area 120 and the fresh air pipe area 130, that is, the fresh air module 30 and the electric control module 40 are arranged side by side along the length direction of the base 10, so that the fresh air module 30 and the electric control module 40 occupy the space on the base 10 in the same length direction, That is, the fresh air module 30 and the electric control module 40 are located at the same end of the base, which is beneficial to shorten the length of the air conditioner indoor unit with the fresh air function.

In some embodiments of the present application, as shown in FIG. 1 , the fresh air module installation area 110 may be located above the electric control module installation area 120 and the fresh air duct area 130 . In some other embodiments of the present application, as shown in FIG. 3 or FIG. 4 , the fresh air module installation area 110 may also be located under the electric control module installation area 120 and the fresh air duct area 130 .

The boundary line 50 between the fresh air module installation area 110 and the electronic control module installation area 120 is a straight line or a curve extending from the fresh air duct area 130. Generally, for the curved outer wall of the fresh air module 30, the boundary line 50 can be aligned with the fresh air area. The arc-shaped outer wall surface of the module 30 is tangent or parallel to the tangent plane. It can be understood that when there is a certain distance between the electronic control module 40 and the fresh air module 30, the dividing line 50 can be a plurality of parallel straight lines, at least one of which passes through the fresh air duct area 130; or, the dividing line 50 can also be electrically The control module 40 is parallel to the side facing the fresh air module 30.

In the above embodiment, since the boundary line 50 between the fresh air module installation area 110 and the electronic control module installation area 120 is a straight line or a curve extending through the fresh air duct area 130, that is, the fresh air duct 20 is located between the fresh air module 30 and the electronic control module. The junction gap between the modules 40 makes the fresh air pipe 20, the fresh air module 30, and the electric control module 40 compactly assembled, which in turn facilitates the reduction of the volume of the air conditioner indoor unit.

In some embodiments of the present application, the electronic control module 40 and the fresh air module 30 can be in direct contact to achieve compact assembly; Condensation phenomenon, the electronic control module 40 and the fresh air module 30 can also be installed at intervals, for example, refer to FIG. Installed at intervals through the arc mounting base 11.

It can be understood that FIG. 1 is only an exemplary embodiment diagram in which the boundary line 50 between the fresh air module installation area 110 and the electric control module installation area 120 passes through the fresh air duct area 130 in the embodiment of the present application. The fresh air duct 20, the fresh air duct The module 30 and the electric control module 40 can also pass through other reasonable layouts, so that the boundary line 50 between the fresh air module installation area 110 and the electric control module installation area 120 passes through the fresh air duct area 130, and reaches the fresh air duct 20, the fresh air module 30, The purpose of compact assembly of the electronic control module 40, for example, refer to Figure 3 and Figure 4, Figure 3 shows another schematic cross-sectional view of the air-conditioning indoor unit in the embodiment of the application, Figure 4 shows the schematic cross-sectional view of the air-conditioning indoor unit in the embodiment of the application Another schematic cross-sectional view of FIG. 1 , wherein the boundary line 50 may pass horizontally or obliquely through the junction of the fresh air module 30 and the electronic control module 40 and pass through the fresh air duct area 130 .

In some embodiments of the present application, the boundary line 50 extends obliquely upward from the fresh air duct area 130, and the electronic control module 40 is installed close to the fresh air module 30 along the boundary line 50. Installing obliquely upward along the dividing line 50 and close to the fresh air module 30 can increase the length of the installation space of the electric control module 40 along the width direction of the base 10 and the length along the height direction of the base 10, which is conducive to increasing the size of the electric control module. 40; at the same time, since the electronic control module 40 is installed obliquely upward along the dividing line 50, an installation space is also formed obliquely below it, which can accommodate the display module and the wind deflector motor.

For example, referring to FIG. 1 , the electric control module 40 is installed close to the fresh air module 30 , and on the cross section of the base 10 perpendicular to its length direction, a display module installation area 140 and/or a guide area 140 below the electric control module installation area 120 are also formed. The wind panel motor installation area 150, the display module installation area 140 and the wind deflector motor installation area 150 are used to respectively install the display module and the wind deflector motor. While the control module 40 is compactly installed, it is convenient to connect the display module and the wind deflector motor.

As an example, in some embodiments of the present application, the display module installation area 140 and the air deflector motor installation area 150 are sequentially arranged below the electronic control module installation area 120 along the length direction of the base 10, wherein the air deflector motor It can be located on the side close to the wind wheel 80, so that the wind deflector motor can control the rotation of the wind deflector 70 corresponding to the length of the wind wheel 80, and the display module on the side away from the wind wheel 80 displays the operating parameters of the air conditioner.

In some other embodiments of the present application, the display module installation area 140 and the wind deflector motor installation area 150 are sequentially arranged below the electric control module installation area 120 along the width direction of the base 10. Generally, the display module installation area 140 is located at At the edge of the base 10, since the display module installation area 140 can have the same length as the electric control module 40, the display module installation area 140 can have more display areas to better provide display functions, while the wind deflector motor is installed The area 150 is located behind the display module installation area 140, and the air deflector motor can be covered by the display module, which is beneficial to reasonably allocate the installation space of the electronic control module 40, the display module, and the air deflector motor.

In some embodiments of the present application, referring to FIG. 1 , the fresh air duct 20 and the electronic control module 40 may be located under the fresh air module 30 , and the electric control module 40 located under the fresh air module 30 may It can be more convenient for wiring or testing. It can be understood that the fresh air duct 20 and the electronic control module 40 can also be arranged in other ways, for example, referring to FIG. 3 and FIG. 4 , the fresh air duct 20 and the electronic control module 40 can also be located above the fresh air module 30 .

Further, in order to facilitate the assembly of the fresh air module 30 , the electronic control module 40 and the fresh air duct 20 to occupy a smaller space and reduce the volume of the air conditioner indoor unit, refer to FIG. 1 , wherein the fresh air module 30 is wider than the fresh air duct 20 diameter and the length of the electric control module 40 along the width direction of the base 10, and the width of the fresh air module 30 is less than or equal to the width of the base 10, that is, the length of the fresh air duct 20 and the electric control module 40 along the width direction of the base 10 is less than The width of the fresh air module 30, so that the fresh air duct 20 and the electric control module 40 can be installed under or above the fresh air module 30 at the same time, so that the fresh air module 30, the electric control module 40 and the fresh air duct 20 occupy the same area of the base 10. The width space is conducive to the reduction of the width of the air conditioner indoor unit.

Similarly, since the volume of the fresh air module 30 is larger than that of the electric control module 40, in order to make the fresh air module 30 and the electric control module 40 occupy a smaller space after assembly, the length of the electric control module 40 along the length direction of the base 10 is smaller than that of the fresh air module 40. The length of the module 30 along the length direction of the base 10, that is, after the electric control module 40 and the fresh air module 30 are assembled, the space occupied by the fresh air module 30 and the electric control module 40 along the length direction of the base 10 is the length of the fresh air module 30 along the length direction of the base 10 The length of the fresh air module 30 and the electric control module 40 after assembly is only the length of the larger fresh air module 30, rather than the sum of the lengths of the fresh air module 30 and the electric control module 40, which in turn facilitates the shortening of the length of the air conditioner indoor unit .
