Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail below. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the examples given herein without making any creative effort, shall fall within the protection scope of the present application.
At present, most of air conditioner indoor unit drainage adopts a water pump to drain condensed water in a water receiving tray, in the related technology, the liquid level height of the condensed water is generally detected through a float type liquid level switch, and the water pump is controlled to drain the condensed water according to the detected liquid level height. However, in the air-conditioning transportation process, the float type liquid level switch can be locked due to bumping, if the float type liquid level switch is clamped at a higher liquid level height, the float type liquid level switch can be mistakenly considered to have a fault, the water full protection fault is reported, and the normal operation is influenced. The statistics of after-sale maintenance of the water pump can also show that most of water pump failures are caused by the fact that the water pump liquid level switch is blocked, so that the reduction or the complete solving of the fault that the water pump liquid level switch is blocked has great significance for reducing the fault rate of the air conditioning unit.
In order to solve this problem, the present application provides a new condensate drain and related solutions, which are described in detail below.
Examples
Referring to fig. 1, fig. 1 is a structural view of a condensed water drainage apparatus according to an embodiment of the present application.
As shown in fig. 1, the present embodiment provides a condensed water drain device applied to an air conditioner, including: the device comprises a main control board 1, a water pump 2 and an electrode 3, wherein the water pump 2 and the electrode 3 are respectively connected with the main control board 1; the electrode 3 is fixedly arranged at a position which is away from the bottom of the water receiving tray 4 of the condensed water by a preset distance so as to prevent movement; the electrode 3 is used for monitoring the change of the liquid level of condensed water in the water receiving tray 4, generating a level signal and sending the level signal to the main control panel 1;
and the main control board 1 is used for controlling the water pump 2 to discharge water according to the level signal corresponding to the liquid level.
The electrode 3 is made of a conductive material, such as a metal, for example, iron. After the electrode 3 contacts water, the resistance changes, correspondingly, the generated level signals are different, and the main control board 1 controls the water pump 2 to drain water according to the level signals corresponding to the liquid level.
It should be noted that the specific implementation manner of the main control panel 1 controlling the water pump 2 to drain water is the existing mature technology, for example, when the liquid level is lower than the set value, the liquid level does not contact the electrode 3, the water pump 2 stops running, the condensed water cannot be drained, and the condensed water will slowly accumulate, when the liquid level rises to the set value, the water pump 2 starts to rotate to normally pump water, and as the condensed water in the water pan 4 is continuously pumped out, the liquid level is reduced, and more water is pumped out, and less water is not pumped out. For another example, different liquid levels correspond to different level signals, and different voltage signals are correspondingly generated to provide the water supply pump 2, so that more water is pumped and less water is pumped. Wherein, the main control board can be the existing main control board.
In the scheme of this application, replaced float formula liquid level switch by electrode 3, through the change of electrode 3 response comdenstion water liquid level and produce level signal, carry out water pump 2's control by main control board 1 according to this, carry out the drainage, because this electrode 3 is fixed the setting, can not take place the activity in the transportation, avoided appearing the dead problem of water pump 2 liquid level switch card among the above-mentioned correlation technique to normal operating has been guaranteed.
In practice, the electrode 3 may have various specific structures. Two structures are illustrated below.
Structure one
Because the atmospheric environment contains various impurities such as dust, the air return opening of the air conditioner sucks air into the unit for refrigeration, the impurities can remain in the evaporator or flow into the water pan 4 along with the condensed water, and as time passes, the water pan 4 has more stains, so that the risk of blocking the water suction opening of the water pump 2 exists, and the air conditioning unit is in failure. To solve this problem, in some embodiments, as shown in fig. 2 and 3, the electrode 3 is a cage-type mesh structure, which covers the water pump 2 and is fixedly connected to the water pump 2. This cage screen panel structure is specific sets up intensive hole on the lateral wall of cage structure, so, with water pump 2 and 3 synthetic integrations of electrode, traditional liquid level switch changes dense hole cage into, but can lead to water but can not lead to great impurity, covers water pump 2, just so can avoid dust impurity or other objects to plug up water pump 2 water absorption opening and lead to water full protection, has avoided liquid level switch's the unusual condition of blocking simultaneously.
In some embodiments, optionally, as shown in fig. 3, the cage-type mesh enclosure structure is cylindrical, so that water can enter the cage-type mesh enclosure structure more smoothly.
In order to prevent the cage type mesh enclosure structure from being blocked by the attachments and affecting the water absorption capacity of the water pump 2, considering that the cage type mesh enclosure structure may have attachments after long-term drainage, in some embodiments, optionally, as shown in fig. 4 and 5, a fan 5 is further included in the cage type mesh enclosure structure; the fan 5 is connected with the main control board 1 and used for rotating under the control of the main control board 1 so as to blow off attachments on the cage type mesh enclosure structure. Generally, the fan 5 includes a motor and a fan blade. In implementation, under the condition that the water pump 2 stops, the motor drives the fan blades to rotate, so that the pressure inside the cage is large, the pressure outside the cage is small, and condensed water is blown out of the cage, so that dust and impurities attached to the surface of the cage type mesh enclosure structure are separated from the surface.
The water suction port of the water pump 2 is preferably of a structure that absorbs water all around, and the water is drained more quickly. Optionally, as shown in fig. 4, in order not to affect the drainage of the water pump 2, the fan 5 is fixed at one end of the water pump 2 close to the water pan 4.
In some embodiments, as shown in fig. 4, the fan 5 and the water pump 2 are coaxially arranged, specifically, a motor shaft of the fan 5 is fixedly connected with a rotating shaft of the water pump 2, when the water pump 2 rotates, the radial attachments are more, and the fan 5 and the water pump can rotate along the same shaft, so that the attachments can be removed more cleanly.
The structure II,
In some embodiments, as shown in fig. 6, the electrode 3 is a strip-shaped structure, and the electrode 3 may be fixedly connected to a side wall of the water-receiving tray 4. Specifically, the electrode 3 may be a metal rod or the like.
In some embodiments, optionally, as shown in fig. 2, 3, 4 and 6, the condensed water drainage device further includes a hollow pipe 6; the water pump 2 is wired and connected to the main control panel 1 through the hollow pipe 6.
