[0051] The present application provides a floor type air conditioner indoor unit.

[0052] Please refer to Figures 1 to 7 The present application provides a floor type air conditioner indoor unit, which comprises a shell 100, a air diffusing assembly 110 and a valve assembly. The shell 100 is provided with a first air outlet 101 and a second air outlet 104, and the shell 100 is provided with a heat exchange air duct 105 communicating with the first air outlet 101 and an air diffusing air duct 108 communicating with the second air outlet 104. The air diffusing assembly 110 is arranged in the air diffusing air duct 108 or at the second air outlet 104, and the air diffusing assembly 110 is adapted for air flow to pass through and diffuse the air flow passing through. The valve assembly 150 is used to connect or disconnect the air diffusing air duct 108 inside the air diffusing assembly 110 and the heat exchange air duct 105.

[0053] In the present application embodiment, the shell 100 extends in the up-down direction as a whole, and the cross-sectional shape of the shell 100 can be circular, oval, rectangular, etc., which can be selected according to actual use requirements, and is not specifically limited here. The shape of the first air outlet 101 and the second air outlet 104 can be strip-shaped, rectangular, oval, etc. Generally, in order to increase the air supply and the air supply range, the first air outlet 101 and the second air outlet 104 are in the form of a strip extending in the up-down direction. The shell 100 is also provided with an air inlet, and of course, the shape of the air inlet can also be strip-shaped, rectangular, oval, etc. The heat exchange air duct 105 communicates the air inlet with the first air outlet 101, and the heat exchange air duct 105 is provided with a heat exchanger, a fan assembly 160 and other structures. The fan assembly 160 is used to drive air to enter the heat exchange air duct 105 from the air inlet and exchange heat with the heat exchanger, and then blow out from the first air outlet 101.

[0054] The air diffusion assembly 110 is arranged at the second air outlet 104 or near the second air outlet 104 of the air diffusion air duct 108, and the overall shape of the air diffusion assembly 110 is matched with the shape of the second air outlet 104. The air diffusion assembly 110 is suitable for air flow to pass through and diffuse the air flow passing therethrough. By using the air diffusion assembly 110, the air blown out of the second air outlet 104 can flow in a diffused manner, that is, the air flow changes the original flow direction after passing through the air diffusion assembly 110 and can flow in different directions, so as to realize the diffused flow of the air and realize the breeze feeling or breeze feeling air outlet. The air diffusion assembly 110 can specifically include an air diffusion grille structure, a cyclone fan wheel 115 structure, a plurality of air diffusion holes and the like, as long as it can realize the diffusion of the air flow passing therethrough. The air diffusion assembly 110 is mounted on the inner surface of the shell 100, and specifically, the air diffusion assembly 110 is fixedly mounted on the inner surface of the shell 100.

[0055] The valve assembly 150 is used to connect or disconnect the air diffusion air duct 108 inside the air diffusion assembly 110 and the heat exchange air duct 105. That is, the valve assembly 150 has a connection position for connecting the heat exchange air duct 105 and the air diffusion air duct 108 inside the air diffusion assembly 110, and a disconnection position for disconnecting the heat exchange air duct 105 and the air diffusion air duct 108 inside the air diffusion assembly 110. When the valve assembly 150 is in the connection position, the heat exchange air duct 105 is connected with the air diffusion air duct 108 inside the air diffusion assembly 110, so that the air flow in the heat exchange air duct 105 can flow into the air diffusion air duct 108, and then be blown out of the second air outlet 104 after being diffused and expanded by the air diffusion assembly 110, so as to realize the breeze feeling or windless feeling. When the valve assembly 150 is in the disconnection position, the heat exchange air duct 105 is not connected with the air diffusion air duct 108 inside the air diffusion assembly 110, so that the air flow in the heat exchange air duct 105 can only be blown out of the first air outlet 101, so as to realize rapid heating and cooling. The valve assembly 150 can be slidingly connected with the shell 100, or can be rotatably connected with the shell 100, that is, the valve assembly 150 can switch between the connection position and the disconnection position by rotating or sliding.

[0056] The floor type air conditioner indoor unit has a first air outlet 101 and a second air outlet 104, and a heat exchange air duct 105 communicating with the first air outlet 101 and a diffusion air duct 108 communicating with the second air outlet 104 are arranged inside the floor type air conditioner indoor unit; a diffusion assembly 110 is arranged in the diffusion air duct 108 or at the second air outlet 104, and the diffusion assembly 110 is adapted for air flow to pass through and diffuse the air flow passing therethrough; a valve assembly 150 is used to open or block the diffusion air duct 108 and the heat exchange air duct 105, so that by switching the position of the valve assembly 150, the floor type air conditioner indoor unit has a normal air outlet mode and a breeze mode. When the floor type air conditioner indoor unit is in the breeze mode, the valve assembly 150 opens the diffusion air duct 108 and the heat exchange air duct 105, so that a part of the air flow is diffused and expanded by the diffusion assembly 110 and blown out from the second air outlet 104 to form a breeze air flow, and another part of the air flow is blown out from the first air outlet 101, that is, the air flow is blown out in at least two directions, thereby effectively increasing the air outlet area of the breeze mode, effectively increasing the air volume of the breeze, and improving the comfort and capacity of the breeze mode. At the same time, the valve assembly 150 is used to adjust the air outlet mode, and the diffusion assembly 110 does not need to be driven by a driving mechanism to move to change the air outlet mode, so that the large movement space required by the movement of the diffusion assembly 110 can be avoided, the installation position of the display box is not occupied, the structural strength requirement of the panel is relatively low, and the cost is reduced.

[0057] It can be understood that the number of the first air outlet 101 can be one, two or more. In an embodiment, in order to increase the air volume, the number of the first air outlet 101 is two. Please refer to Figure 1 and Figure 2 , the first air outlet 101 includes a left air outlet 102 and a right air outlet 103 located on opposite sides of the second air outlet 104. Accordingly, the heat exchange air duct 105 includes a left air duct 106 communicating with the left air outlet 102 and a right air duct 107 communicating with the right air outlet 103. In this embodiment, by arranging the left air outlet 102 and the right air outlet 103, and arranging the left air outlet 102 and the right air outlet 103 on opposite sides of the second air outlet 104, the air flow of the floor type air conditioner indoor unit can be blown out in three directions, thereby further increasing the air outlet area of the breeze mode, further increasing the air volume of the breeze, and improving the comfort and capacity of the breeze mode.

[0058] Specifically, the indoor unit of the floor air conditioner 100 further comprises a left volute assembly 130 and a right volute assembly 140. The left volute assembly 130 comprises a left volute 131 and a left volute tongue 132, and the left volute 131 and the left volute tongue 132 surround to form the left air duct 106. The right volute assembly 140 comprises a right volute 141 and a right volute tongue 142, and the right volute 141 and the right volute tongue 142 surround to form the right air duct 107. In this embodiment, the fan assembly 160 comprises a first cross-flow fan 161 and a second cross-flow fan 162. The first cross-flow fan 161 is arranged in the left air duct 106, and the second cross-flow fan 162 is arranged in the right air duct 107.

[0059] Please also refer to Figure 2 The air diffusing air duct 108 is formed between the left air duct 106 and the right air duct 107. The valve assembly 150 comprises a first valve 151 and a second valve 152. The first valve 151 is used to connect or disconnect the air diffusing air duct 108 located inside the air diffusing assembly 110 with the left air duct 106. The second valve 152 is used to connect or disconnect the air diffusing air duct 108 located inside the air diffusing assembly 110 with the right air duct 107.

[0060] That is, the first valve 151 has a connection position for connecting the left air duct 106 with the air diffusing air duct 108 located inside the air diffusing assembly 110, and a disconnection position for disconnecting the left air duct 106 with the air diffusing air duct 108 located inside the air diffusing assembly 110. The second valve 152 has a connection position for connecting the right air duct 107 with the air diffusing air duct 108 located inside the air diffusing assembly 110, and a disconnection position for disconnecting the right air duct 107 with the air diffusing air duct 108 located inside the air diffusing assembly 110. When the first valve 151 is in the connection position, the air flow in the left air duct 106 can flow into the air diffusing air duct 108, and then be blown out from the second air outlet 104 after air diffusion by the air diffusing assembly 110, so as to realize the feeling of breeze or no wind. When the second valve 152 is in the connection position, the air flow in the right air duct 107 can flow into the air diffusing air duct 108, and then be blown out from the second air outlet 104 after air diffusion by the air diffusing assembly 110, so as to realize the feeling of breeze or no wind.

[0061] The first valve 151 and the second valve 152 can be in sliding connection with the shell 100, or in rotating connection with the shell 100, and are not specifically limited. In an embodiment, please refer to Figure 2 and Figure 5 The first valve 151 and the second valve 152 are in rotating connection with the shell 100. Specifically, the first valve 151 and the second valve 152 extend in the up-down direction. The first valve 151 has an axis extending along the length direction thereof, and the second valve 152 has an axis extending along the length direction thereof.

[0062] It can be understood that, in order to better drive the first valve 151 and the second valve 152 to rotate, the floor type air conditioner indoor unit further comprises a first driving device 153 and a second driving device 154, the first driving device 153 is connected to the first valve 151 to drive the first valve 151 to rotate around an axis extending along the length direction of the first valve 151, so as to guide the left air duct 106 and the air distribution duct 108 to be connected or disconnected; the second driving device 154 is connected to the second valve 152 to drive the second valve 152 to rotate around an axis extending along the length direction of the second valve 152, so as to guide the right air duct 107 and the air distribution duct 108 to be connected or disconnected. Specifically, the first driving device 153 is a driving motor, and the second driving device 154 is a driving motor, but is not limited thereto.

[0063] Please refer to Figure 2 , the air distribution duct 108 is formed by the shell 100, the left volute 131, the right volute 141, the first valve 151, and the second valve 152. Specifically, when the first valve 151 disconnects the left air duct 106 and the air distribution duct 108 located inside the air distribution assembly 110, the free end of the first valve 151 abuts against the wall surface of the left volute 131; when the second valve 152 disconnects the right air duct 107 and the air distribution duct 108 located inside the air distribution assembly 110, the free end of the second valve 152 abuts against the wall surface of the right volute 141. In an embodiment, in order to prevent the airflow in the air distribution duct 108 from flowing into the shell 100 to cause air mixing, a partition plate 170 (as shown in Figure 2 ) can be arranged between the left volute 131 and the right volute 141, and the partition plate 170 connects the left volute 131 and the right volute 141. In addition, in order to better install the valve, a valve installation cavity can be arranged on the shell for installing the valve. Specifically, the shell comprises a panel and a panel reinforcing plate, and the valve installation cavity can be formed on the panel reinforcing plate.

[0064] Please refer to Figures 1 to 7 , in the embodiment of the present application, the floor type air conditioner indoor unit further comprises a switch door assembly 180. In some embodiments, the switch door assembly 180 is slidingly installed on the outer surface of the shell 100, but is not limited thereto.

[0065] The switch door assembly 180 has an open position, when the switch door assembly 180 is in the open position, the switch door assembly 180 at least partially opens the first air outlet 101 and / or the second air outlet 104 (as shown in Figure 5(As shown). It is understood that "at least partially open" means partially opening the first air outlet 101 and / or the second air outlet 104, or fully opening the first air outlet 101 and / or the second air outlet 104. Specifically, the door opening assembly 180 at least partially opens the first air outlet 101 and / or the second air outlet 104, meaning that the door opening assembly 180 at least partially opens the first air outlet 101, and / or the door opening assembly 180 at least partially opens the second air outlet 104.

[0066] Furthermore, the door opening and closing assembly 180 also has a first closed position and a second closed position. When the door opening and closing assembly 180 is in the first closed position, the door opening and closing assembly 180 completely closes the first air outlet 101; when the door opening and closing assembly 180 is in the second closed position, the door opening and closing assembly 180 completely closes the second air outlet 104 (e.g., Figure 7 (As shown).

[0067] In some embodiments, the curvature of the sliding trajectory of the door opening / closing assembly 180 from the first closed position to the open position is greater than the curvature of the sliding trajectory of the door opening / closing assembly 180 from the open position to the second closed position. Thus, when the indoor unit of the floor-standing air conditioner is in the low-wind mode, such as... Figure 5 As shown, the door opening and closing assembly 180 slides from the first closed position to the open position. At this time, the door opening and closing assembly 180 partially opens the first air outlet 101 and fully opens the second air outlet 104. Part of the airflow inside the air conditioner is dispersed and amplified by the air diffusion assembly 110 and blown out from the second air outlet 104 to form a gentle breeze. The other part is blown out from the first air outlet 101. That is, the airflow is dispersed and blown out in at least two directions, thereby effectively increasing the air outlet area of ​​the gentle breeze mode, effectively increasing the air volume of the gentle breeze mode, and improving the comfort and capability of the gentle breeze mode.

[0068] Specifically, the door opening / closing assembly 180 includes a left door 181 and a right door 182. The left door 181 is slidably mounted at the left air vent 102, and the right door 182 is slidably mounted at the right air vent 103. When the door opening / closing assembly 180 is in the open position, as... Figure 4 and Figure 5 As shown, the left and right opening / closing doors 181 and 182 fully open the second air outlet 104, with the left door 181 partially opening the left air outlet 102 (enclosing a leakage triangle area), and the right door 182 partially opening the right air outlet 103 (enclosing a leakage triangle area). When the door assembly 180 is in the first closed position, as... Figure 1 and Figure 2As shown, the left shutter door 181 completely closes the left air outlet 102, and the right shutter door 182 completely closes the right air outlet 103. When the shutter door assembly 180 is in the second closed position, as shown in Figure 6 and Figure 7 As shown, the left shutter door 181 and the right shutter door 182 jointly completely close the second air outlet 104.

[0073] In some embodiments, referring to Figure 10 , the air diffusion assembly 110 comprises a mounting plate 111 and a cyclone fan 115, the mounting plate 111 extends along the length direction of the second air outlet 104, the mounting plate 111 is provided with a mounting through hole 112, and the cyclone fan 115 is correspondingly mounted at the mounting through hole 112. The cyclone fan 115 can be fixedly mounted at the mounting through hole 112 of the mounting plate 111 or rotatably mounted at the mounting through hole 112 of the mounting plate 111. Specifically, the cyclone fan 115 is an axial flow fan. In some embodiments, two layers of fans can be provided, one of which is a static fan and the other of which is a dynamic fan. It can be understood that the cyclone fan 115 refers to that the blades of the cyclone fan 115 are curved or arranged at an angle with the air inlet direction, so that the air flow passing through the cyclone fan 115 forms a cyclone or the air inlet direction is inconsistent with the air outlet direction. In this way, the air flow can be effectively diffused and agitated, the air outlet is more gentle, the air resistance and air loss are small, and the windless wind volume can be effectively improved.

[0074] For example, the cyclone fan 115 comprises a first fan 116 and a second fan 117, the first fan 116 is fixedly connected at the mounting through hole 112, and the second fan 117 is rotatably mounted at the mounting through hole 112, so that the blades of the second fan 117 and the blades of the first fan 116 are arranged in a mutually laminated or staggered manner in the air passing direction of the mounting through hole 112. In order to make the air flow blown out of the mounting through hole 112 be the air flow diffused and blown out by the first fan 116 and the second fan 117, it is preferred that the mounting through hole 112 is circularly arranged and the size of the mounting through hole 112 is adapted to the size of the first fan 116 and the second fan 117.

The rotation of the second wind wheel 117 can be driven by a driving motor, or can be driven by a rolling bearing or the like, so that the second wind wheel 117 can automatically rotate under the driving of the airflow.

[0076] It should be noted that the first wind wheel 116 and the second wind wheel 117 are both installed at the installation through hole 112, and are arranged in a stacked or staggered manner in the airflow direction of the installation through hole 112, so that the first wind wheel 116 and the second wind wheel 117 are arranged in sequence in the airflow direction of the installation through hole 112. The installation through hole 112 plays a role of guiding and guiding the airflow. The number and size of the blades of the first wind wheel 116 and the number and size of the blades of the second wind wheel 117 can be the same or different. By fixing the first wind wheel 116 at the installation through hole 112 and rotating the second wind wheel 117 at the installation through hole 112, on the one hand, the airflow is driven to blow out of the installation through hole 112, reducing wind resistance and wind loss, effectively improving air volume, and flexibly controlling the strength of the airflow, on the other hand, the blades of the second wind wheel 117 and the blades of the first wind wheel 116 are overlapped or staggered, so that the airflow passing through the installation through hole 112 is continuously cut, scattered, divided and stirred by the first wind wheel 116 and the second wind wheel 117, so that the outflow is softer, the windless effect is greatly improved, and the divergence direction of the airflow is controllable and adjustable.
