Fig. 1 is a schematic sectional view of a condensate water treatment apparatus and a water pan according to an embodiment of the present utility model, as shown in fig. 1, and referring to fig. 2 to 5, an embodiment of the present utility model provides a condensate water treatment apparatus 10 of an air conditioner, including a drainage apparatus 104 for draining waste water, a water using apparatus 102, and a turning apparatus 101. The drain water inlet 1041 of the drain device 104 is disposed below the water outlet 401 of the water pan of the air conditioner. The water-using device 102 has a water inlet provided below the water outlet 401 of the water-receiving tray. The steering device 101 is rotatably or movably arranged, the steering device 101 being configured to be brought into at least a first state and a second state by rotation or movement. In the first state, the steering device 101 establishes a fluid connection between the water outlet 401 of the drip tray and the water inlet; in the second state, the steering device 101 establishes a fluid connection between the water outlet 401 of the drip tray and the drain water inlet 1041.

In this embodiment, the water-using device 102 can be a plurality of recycling condensed water devices. For example, the water device 102 may be a water storage device having a certain capacity to store a certain amount of condensed water for reuse by other devices. For example, the water device 102 may also be a humidifying device, and condensed water is pumped to a heat exchanger or evaporated in an air duct after entering the water device 102 to humidify indoor air. For example, the water device 102 may also be a humidifier, and the condensed water is atomized and blown out through the air outlet after entering the water device 102. For example, the water-using device 102 may be a cooling device, and the condensed water is pumped to the condenser after entering the water-using device 102, so as to reduce the temperature of the condenser and improve the heat dissipation efficiency of the condenser. For example, the water usage device 102 may also be a self-cleaning device, and the condensed water is sprayed into the surface of the heat exchanger or the air duct after entering the water usage device 102 to remove dust and sundries on the heat exchanger or the air duct.

In the condensate water treatment apparatus of an air conditioner according to the embodiment of the present utility model, in the first state, condensate water in the water pan 40 enters the steering apparatus 101 and enters the water using apparatus 102 through the water inlet, and in the second state, condensate water in the water pan 40 enters the steering apparatus 101 and enters the drainage apparatus 104 through the drainage water inlet 1041, and is drained by the drainage apparatus 104. Due to the arrangement of the steering device 101, the steering device 101 rotates and moves to a corresponding state, so that the condensed water in the water receiving disc 40 can enter the water using device 102 or the water draining device 104 to finish the treatment of the water in the water receiving disc 40, and when the condensed water is prevented from overflowing or the impurity and dust in the condensed water are excessive, or the condensed water is not needed to be reused, the steering device 101 is in a second state to directly drain the condensed water. Thus, on the one hand, the condensed water can be prevented from entering the water using device 102, and the condensed water is prevented from getting damp and moldy after being not used for a long time. On the other hand, clogging of the related equipment or piping caused when impurities and dust are extracted along with the condensed water and reused can be avoided. When the condensed water in the water pan 40 needs to be reused, the steering device 101 is in the first state, and the condensed water enters the water using device 102. The condensed water can be treated by only one steering device 101, and the connection is not needed by redundant connecting devices, so that the structure is very simple, the installation is convenient, and the production cost is low.

In the present embodiment, when the air conditioner is in the cleaning mode, that is, the condensed water with the impurities and dust carried in the water receiving tray 40 is discharged, the turning device 101 is in the second state. When the air conditioner is in the default mode, i.e., the non-cleaning mode, the turning device 101 is in the first state, and condensed water flows into the water using device 102 for recycling.

In some embodiments of the utility model, the turning device 101 comprises a first flow channel and a second flow channel. The steering device 101 is rotatably provided. In the first state, the water outlet 401 of the drip tray and the water inlet are fluidly connected via the first flow path. In the second state, the water outlet 401 of the drip tray and the drain water inlet 1041 are fluidly connected via a second flow path.

In this embodiment, when the steering device 101 is in the first state, the condensed water enters the water device 102 through the first flow passage, and when the steering device 101 is in the second state, the condensed water enters the water drain device 104 through the second flow passage. The operation is very simple, and the use is convenient.

In some embodiments of the present utility model, as shown in fig. 1, the steering device 101 includes a water chamber 1012 disposed therein and a steering water outlet 1013 in communication with the water chamber 1012. The water chamber 1012 is communicated with the water outlet 401 of the water pan. The turning device 101 is turned or moved to selectively communicate the turning water outlet 1013 with the drain water inlet 1041 or with the water inlet, thereby selectively flowing the water in the water receiving tray 40 to the water using device 102 or the drain device 104.

In this embodiment, the condensed water in the water pan 40 enters the water chamber 1012 through the water outlet 401 of the water pan, and the turning device 101 rotates or moves to enable the water in the water chamber 1012 to flow to the drain water inlet 1041 through the turning water outlet 1013 to enter the drain device 104 or to flow to the water inlet to enter the water device 102, so as to finish the treatment of the condensed water. The water in the same water cavity 1012 can flow to two different places to finish the treatment by only controlling the turntable of the steering device 101, which is very simple and convenient.

In some embodiments of the utility model, as shown in FIG. 1, the steering device 101 is a steering box, and the steering device 101 further includes a steering inlet 1011 in communication with the water chamber 1012. The diversion inlet 1011 is always below the water outlet 401 of the drip tray.

In this embodiment, the condensate water enters the diversion inlet 1011 from top to bottom through the water outlet 401 of the water pan and then enters the water cavity 1012. Because the diversion water inlet 1011 is always positioned below the water outlet 401 of the water receiving disc, the condensed water can be discharged by utilizing the gravity effect, and the independent water diversion device is not needed, so that the structure of the condensed water treatment device 10 is simpler, and the cost is saved under the condition of not affecting the effect.

In some embodiments of the present utility model, as shown in fig. 2, the water outlet 401 of the drip tray is always inserted into the diversion inlet 1011.

In this embodiment, no matter how the steering device 101 rotates or moves, the condensed water in the water receiving disc 40 always flows into the steering water inlet 1011 through the water outlet 401 of the water receiving disc, so that the condensed water is prevented from leaking out during the rotation or movement process of the steering device 101, and the condensed water drops into the air conditioner, thereby damaging devices in the air conditioner.

In some embodiments of the utility model, the diverting inlet 1011 includes oppositely disposed first and second edges 1014, 1015. In one of the first and second states, the first edge 1014 is below the water outlet 401 of the drip tray and the second edge 1015 is above the water outlet 401 of the drip tray. In the other of the first and second states, the first edge 1014 is above the water outlet 401 of the drip tray and the second edge 1015 is above the water outlet 401 of the drip tray.

In this embodiment, when the turning device 101 is in the first state, the turning water outlet 1013 supplies water to the water device 102, the first edge 1014 is lower than the water outlet 401 of the water tray, the second edge 1015 is higher than the water outlet 401 of the water tray, and water can flow into the water device 102 along the surface of the first edge 1014. When the water device is installed, the water outlet 401 of the edge water receiving tray moves into the steering water inlet 1011 when the component of the water device is pushed inwards, so that the installation is convenient. When the steering device 101 is in the second state, the steering water outlet 1013 supplies water to the drainage device 104, the first edge 1014 and the second edge 1015 are both higher than the water outlet 401 of the water receiving disc, so that all condensed water enters the drainage device 104, and if the condensed water contains impurities and dust, the first edge 1014 and the second edge 1015 higher than the water outlet 401 of the water receiving disc can also prevent the condensed water from leaking outside in the process of entering the steering device 101, thereby playing a certain role in protecting the air conditioner.

In some embodiments of the present utility model, as shown in fig. 1, 3 and 5, the steering device 101 is rotatably disposed on the drainage device 104 or the water using device 102 around a horizontal rotation axis. The steering device 101 is also drivingly connected to a motor 103 to establish a first state and a second state by rotation driven by the motor 103.

In this embodiment, the motor 103 drives the steering device 101 to rotate through the rotating shaft, so that the steering device 101 is in the first state or the second state. The motor 103 is electrically connected with a control system of the air conditioner, and a user can control the steering device 101 only by operating the control system, so that the use is simple and quick.

The steering device 101 provided in the drain device 104 or the water using device 102, that is, the steering device 101 is very close to one of the drain device 104 and the water using device 102, and the first state and the second state can be completed by steering at a small angle.

Preferably, the steering device 101 is disposed on the water using device 102 and between the water draining device 104 and the water using device 102, so that the first state and the second state can be further realized under the condition that the steering of the steering device 101 is smaller.

In some embodiments of the present utility model, the water drain 104 comprises a first water tank having a drain water inlet 1041 at an upper end, and the water using device 102 comprises a second water tank having a water inlet at an upper end. The condensate water treatment apparatus 10 further includes a connection port at a preset height of the second water tank, the connection port connecting the first water tank and the second water tank.

In this embodiment, the connection port connects the first water tank and the second water tank, that is, water in one of the first water tank and the second water tank may flow into the other water tank through the connection port.

Preferably, the preset distance is the height of the second tank, that is, the connection port is at the top of the second tank. In this embodiment, the connector is used for discharging the unnecessary comdenstion water in the second water tank, avoids the second water tank to condense too much and overflow from other positions. By arranging the connecting ports, the redundant condensed water can be automatically discharged, so that a water level sensor is not additionally arranged in the connecting ports, and the overall cost of the air conditioner in the whole machine production is saved.

In some embodiments of the utility model, the connection port is on the underside of the turn water outlet 1013. The condensate water treatment apparatus 10 further includes a water guide 105, the water guide 105 being formed by a lower sidewall of the connection port extending a distance toward the direction of the first tank. The end of the water guiding means 105 facing the first water tank extends into the first water tank.

In this embodiment, water in the second water tank exceeding the water level of the connection port enters the first water tank through the water guiding device 105. Moreover, because a gap with a certain width may exist between the first water tank and the second water tank, the water guide device 105 extends for a distance towards the direction of the first water tank, so that water cannot enter the gap, water leakage of the air conditioner is avoided, and user experience is improved.

In some alternative embodiments of the utility model, the second water tank is provided with an outlet which communicates with the outside of the air conditioner, through which the water in the second water tank can flow out of the air conditioner in case of overfilling or excessive impurities.

In some embodiments of the present utility model, as shown in fig. 1, the water guiding device 105 is disposed obliquely, and one end of the water guiding device 105 extending into the first water tank is lower than the lower side wall of the connection port.

In this embodiment, water in the second water tank may enter the water guiding device 105 inclined towards the bottom of the first water tank through the connection port, and the inclined water guiding device 105 may reduce the resistance of water in the flowing process, so that the water circulation is smoother.

In addition, the water guide device 105 which is inclined towards the bottom of the first water tank can reduce the possibility that condensed water entering the first water tank enters the second water tank along the water guide device 105, so that the purity of the water in the second water tank is ensured to a certain degree.

In some embodiments of the utility model, the connection port extends upwardly through the second tank. The water guide 105 is located above the corresponding side wall of the first tank. The connecting ports are positioned at the upper ends of the corresponding side walls of the second water tank.

In this embodiment, the connection port of the second water tank is penetrated upwards, that is, the steering water outlet 1013 of the steering device 101 rotates in the connection port, and the connection port is located on the corresponding side wall of the first water tank and the second water tank, so that the condensed water fully enters the first water tank or the second water tank, and the condensed water is better prevented from splashing.

In some embodiments of the utility model, the first water tank and the second water tank are disposed adjacent. The first water tank has a smaller volume than the second water tank.

In this embodiment, since the first water tank is used for draining water and does not need to store water, only a smaller volume is needed, and the space occupation is reduced, so that the volume of the condensate water treatment apparatus 10 is reduced. Alternatively, in the case where the overall space of the condensate water treatment apparatus 10 is unchanged, the second tank is made to have a larger volume to store more condensate water.

An embodiment of the present utility model provides an indoor unit of an air conditioner, as shown in fig. 4, including an evaporator 20 and a water pan 40. Also included is the condensate water treatment apparatus 10 described in the above embodiments. The water pan 40 is disposed below the evaporator 20.

In this embodiment, condensed water generated during the heat exchange of the evaporator 20 also falls into the water pan 40. The water pan 40 prevents condensed water from falling on other parts inside the air conditioner indoor unit, and protects the air conditioner indoor unit. But also gathers condensed water, and lays a foundation for further treatment of the condensed water.

In some embodiments of the present utility model, the air conditioner indoor unit further includes a humidifying device and a water pump. The humidifying device is used to supply water to the evaporator 20. The humidifying device is communicated with a second water tank of the condensed water processing device 10 through a water pipe 30, and water in the second water tank is led into the humidifying device through a water pump so as to realize water supply to the humidifying device.

By now it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the utility model have been shown and described herein in detail, many other variations or modifications of the utility model consistent with the principles of the utility model may be directly ascertained or inferred from the present disclosure without departing from the spirit and scope of the utility model. Accordingly, the scope of the present utility model should be understood and deemed to cover all such other variations or modifications.
