[0059] Figure 1 is a schematic structural diagram of an electric three-way valve 10 according to an embodiment of the utility model, as shown Figure 1 As shown, and refer to Figures 2 to 8 The embodiment of the utility model provides an electric three-way valve 10 for an air conditioner, comprising a diverter cavity 100, a rotating block 200 and a driving device. The diverter cavity 100 has a diverter cavity, and a first outlet 101 and a second outlet 102 are arranged on the cavity wall of the diverter cavity. The rotating block 200 is rotatably installed in the diverter cavity to rotate to a first position of blocking the first outlet 101 and opening the second outlet 102, or to a second position of blocking the second outlet 102 and opening the first outlet 101, or to a third position of simultaneously opening the first outlet 101 and the second outlet 102. The driving device is configured to drive the rotating block 200 to rotate.

[0060] Driven by the driving device, the rotating block 200 is rotatably installed in the diverter cavity. The refrigerant enters the diverter cavity. When only the first outlet 101 is needed to flow out the refrigerant, the rotating block 200 rotates to the second position of blocking the second outlet 102 and opening the first outlet 101, and the refrigerant flows out from the first outlet 101. When only the second outlet 102 is needed to flow out the refrigerant, the rotating block 200 rotates to the first position of blocking the first outlet 101 and opening the second outlet 102, and the refrigerant flows out through the second outlet 102. When the first outlet 101 and the second outlet 102 are needed to flow out the refrigerant at the same time, the rotating block 200 rotates to the third position, and the refrigerant flows out through the first outlet 101 and the second outlet 102. The above arrangement enables the rotating block to have at least three positions, so that the first outlet and the second outlet can selectively flow out the refrigerant, or can flow out the refrigerant at the same time. The above arrangement enables the three-way valve to have a variety of refrigerant outflow modes, thereby improving the user experience.

[0061] In some embodiments of the utility model, the three-way valve 10 further includes a guide device, which is configured to allow the rotating block 200 to rotate in a first direction when it moves from the third position to the first position, and to rotate in a second direction when it moves from the third position to the second position, wherein the first direction and the second direction are opposite. The setting of the guide device allows the rotating block 200 to move along a set track of the guide device, thereby preventing the rotating block from colliding with other structures.

[0062] Furthermore, in some embodiments of the present invention, the guide device is also configured to have a limiting function, so that when the rotating block 200 moves to the first position, the rotating block is prevented from continuing to rotate in the first direction, and when the rotating block 200 moves to the second position, the rotating block is prevented from continuing to rotate in the second direction. The setting of the limiting function makes the rotating block rotate more accurately, ensuring that it can accurately move to the first position, the second position or the third position.

[0063] Further, in some embodiments of the utility model, as shown in the figure, the guide device includes a guide groove 108 and a protrusion, and the protrusion is inserted into the guide groove 108. One of the guide groove 108 and the protrusion is set on the cavity wall of the diverter cavity, and the other is set on the rotating block. For example, the guide groove 108 is set on the cavity wall of the diverter cavity, and the protrusion is set on the rotating block, and the protrusion is set on the side of the rotating block facing the guide groove.

[0064] In some embodiments of the present invention, Figure 2 As shown, a refrigerant inlet is also provided on the cavity wall of the diverter cavity. The rotating block includes a flow guide surface 210, and the flow guide surface 210 has a first end 201 and a second end 202 arranged opposite to each other. When the rotating block is in a first position, the refrigerant inlet and the second outlet are on the same side of the flow guide surface 210, and the first end 201 is adjacent to the refrigerant inlet. When the rotating block is in a second position, the refrigerant inlet and the first outlet are on the same side of the flow guide surface 210, and the second end 202 is adjacent to the refrigerant inlet. When the rotating block is in a third position, the refrigerant inlet, the first outlet and the second outlet are on the same side of the flow guide surface 210.

[0065] When the rotating block is in the first position, the refrigerant entering from the refrigerant inlet passes through the first end 201 and enters the second outlet under the guidance of the guide surface 210. When the rotating block is in the second position, the refrigerant entering from the refrigerant inlet passes through the second end 202 and enters the first outlet under the guidance of the guide surface 210. When the rotating block is in the third position, part of the refrigerant entering from the refrigerant inlet enters the first outlet and the second outlet, and the other part flows back through the blocking of the guide surface 210 and enters the first outlet and the second outlet. The setting of the guide surface 210 is conducive to the smooth outflow of the refrigerant and improves the outflow speed of the refrigerant.

[0066] In some embodiments of the present invention, Figure 2 As shown, the drainage surface 210 is a plane.

[0067] In some alternative embodiments of the present invention, the guide surface 210 is a curved surface, and when the rotating block is at the third position, the curved surface arches in a direction away from the refrigerant inlet.

The first outlet and the second outlet can be arranged on the first wall surface. Preferably, the first outlet and the second outlet are arranged on the peripheral wall surface, and this arrangement is conducive to reducing the overall installation volume of the three-way valve. When the refrigerant inlet, the first outlet and the second outlet are all arranged on the peripheral wall surface, the pipeline can be directly connected to the refrigerant inlet, the first outlet and the second outlet. If the first outlet and the second outlet are arranged on the first wall surface, the pipelines connected to the first outlet and the second outlet need to have a bend to ensure that the pipelines connected to the first outlet and the second outlet extend to both sides of the three-way valve.

[0069] In other embodiments of the utility model, the refrigerant inlet is arranged on the first wall surface. The first outlet and the second outlet can be arranged on the second wall surface, and the first outlet and the second outlet can also be arranged on the peripheral wall surface. Preferably, the first outlet and the second outlet are arranged on the peripheral wall surface.

[0076] When the driving coil is energized, a magnetic field is generated around it, and the magnet is rotated in the magnetic field due to the magnetic force. By changing the magnitude and direction of the current, the rotation direction and speed of the magnet can be controlled. The rotation of the magnet drives the driving shaft to rotate. The rotation of the driving shaft drives the first gear to rotate, and the first gear drives the meshing second gear to rotate, and the second gear drives the rotating shaft to rotate, thereby realizing the rotation switching of the rotating block 200 between the first position, the second position and the third position.

The refrigerant flows out from the first outlet 101 and / or the second outlet 102, and enters the corresponding first evaporator 71 and the second evaporator 72 to achieve heat exchange with the airflow flowing through the surface of the first evaporator 71 and / or the airflow flowing through the surface of the second evaporator 72.

[0086] In some embodiments of the present invention, Figure 5 and Figure 6As shown, the indoor unit further includes a housing 80 and an air mixing fan 86. The housing 80 has a first air supply duct 81 and a second air supply duct 82, and a mixed air inlet 85, a first air outlet 87 and a second air outlet 88 are arranged on the front wall of the housing 80, wherein the first air supply duct 81 and the second air supply duct 82 are arranged in sequence along the width direction of the housing 80, a first connecting port 83 is arranged on the side wall of the first air supply duct 81 facing the second air supply duct 82, and a second connecting port 84 is arranged on the side wall of the second air supply duct 82 facing the first air supply duct 81. The mixed air inlet 85 is arranged between the first air supply duct 81 and the second air supply duct 82. The air mixing fan 86 is disposed in the shell 80 and is located between the first air supply duct 81 and the second air supply duct 82. It is configured to promote air flow to enter the shell 80 from the air mixing inlet 85 and enter the first air supply duct 81 through the first connecting port 83 and enter the second air supply duct 82 through the second connecting port 84.

[0087] When the indoor unit of the air conditioner is working, the air mixing fan 86 starts to work, and the indoor air is sucked into the housing 80 by the air mixing inlet 85. Then, under the action of the air mixing fan 86, a part of the indoor air enters the first air supply duct through the first connecting port 83, and the indoor air is mixed with the heat exchange air in the first air supply duct before being blown out indoors. Another part of the indoor air enters the second air supply duct through the second connecting port 84, and the indoor air is mixed with the heat exchange air in the second air supply duct before being blown out indoors. Since the wind blown out of the first air supply duct and the second air supply duct is a mixed wind of the heat exchange air and the indoor air, when the indoor unit of the air conditioner is in the cooling mode, the indoor air can neutralize the relatively strong cold wind, so that the wind blown out of the indoor unit of the air conditioner is cool but not cold. When the indoor unit of the air conditioner is in the heating mode, the indoor air can neutralize the relatively strong warm wind, so that the wind blown out of the indoor unit of the air conditioner is warm but not dry, thereby improving the user experience.

[0088] In some embodiments of the present invention, Figure 6 As shown, the indoor unit of the air conditioner further includes a first baffle. The first baffle is movably disposed in the housing 80 and configured to close the first communication port 83.

[0089] In some embodiments of the present invention, Figure 6 As shown, the indoor unit of the air conditioner further includes a second baffle. The second baffle is movably disposed in the housing 80 and configured to close the second communication port 84.

[0090] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived from the contents disclosed in the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all such other variations or modifications.
