Detailed Description

First, it should be understood by those skilled in the art that these embodiments are merely for explaining the technical principles of the present invention, and are not intended to limit the scope of the present invention. And can be adjusted as needed by those skilled in the art to suit particular applications.

Next, it should be noted that in the description of the present invention, the terms of direction or positional relationship indicated by the terms "inside", "outside", and the like are based on the direction or positional relationship shown in the drawings, which are only for convenience of description, and do not indicate or imply that the device or member must have a specific orientation, be constructed in a specific orientation, and operate, and thus, should not be construed as limiting the present invention.

Furthermore, it should be noted that, in the description of the present invention, unless otherwise explicitly specified or limited, the terms "connected" and "connected" should be interpreted broadly, e.g., as being fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; the two components can be directly connected or indirectly connected through an intermediate medium, and the two components can be communicated with each other. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

The terms "upper", "lower", "top", "bottom" and the like as used herein refer to the orientation of the air conditioner in the normal operation state. The foregoing directional terms are used for convenience of description only and do not constitute any limitation on the structure. The terms "front" and "rear" as used herein refer to the orientation of the user's face to the air conditioner, with the side closer to the user being "front" and the side away from the user being "rear".

In the related art, an air cleaning apparatus in an air conditioner generates a water curtain by a water washing assembly, and performs water washing and humidification on air passing through the water curtain. In the water washing process, the air can take away a plurality of water molecules in the water curtain, so that the water in the water tank can be continuously reduced in the water washing process. When the water level in the water tank is insufficient, the water washing effect of the air purification device is affected, and in order to form the water curtain, the water level in the water tank cannot be too high, that is, to achieve a good water washing effect, the water in the water tank needs to be maintained within a certain water level range. Because the water tank is independent water source, therefore the user need carry out the moisturizing action to the water tank frequently, and it is inconvenient to use.

In order to solve the above problems, embodiments of the present invention provide an air conditioner, in which a water diversion channel is disposed in the air conditioner to guide water in a water pan to a water tank, so that the water tank can be replenished with the water pan, the water replenishment frequency of a user to the water tank is greatly reduced, and the user experience is optimized.

The diversion channel 40 may be formed by a structure inside the housing 10, for example, by providing an elongated hollow structure on the inner wall surface of the housing 10 and forming the diversion channel 40 by the hollow structure, or by providing a diversion pipe inside the housing 10 and forming the diversion channel 40 by the diversion pipe. For example, in the embodiment shown in fig. 1, a water conduit is disposed in the housing 10, one end of the water conduit is connected to the water pan 22, and the other end is connected to the housing 33, and the water conduit is preferably disposed to fit the inner wall of the housing 10. The leading water pipe can be a hose or a rigid pipe, when the leading water pipe is a hose, the leading water pipe is fixed on the side wall of the shell 10 through a buckle structure, and when the leading water pipe is a rigid pipe, the rigid pipe is directly attached to the inner wall surface of the shell 10.

In the embodiment where the heat exchanging device 20 is disposed above the air purifying device 30, the water in the water receiving tray 22 automatically flows into the water tank 31, and in order to achieve a good water washing effect, the water level in the water tank 31 needs to be within a certain height range, and if the amount of the condensed water flowing into the water tank 31 from the water receiving tray 22 is too much, the water washing effect of the air purifying device 30 on the air is affected.

In order to solve the above problem, in one embodiment, a liquid level detection device is disposed in the water tank 31, and a solenoid valve is disposed on the diversion channel 40. When the liquid level in the water tank 31 detected by the liquid level detection device is higher than the first liquid level, the control electromagnetic valve is closed, so that water is stopped being supplemented into the water tank 31, and the water level in the water tank 31 is prevented from being too high. When the liquid level in the water tank 31 detected by the liquid level detecting means is lower than the second liquid level, the control solenoid valve is opened, thereby continuing to replenish water into the water tank 31.

In another embodiment, a liquid level detecting device is disposed in the water tank 31, the drain port of the water pan 22 is connected to a switching valve, one outlet end of the switching valve is connected to the water diversion flow channel 40, and the other outlet end of the switching valve is connected to a first drain pipe leading out of the air conditioner, for example, the drain port of the first drain pipe is located outdoors. When the liquid level in the water tank 31 that the liquid level detection device detected is higher than first liquid level, the control diverter valve communicates water collector 22 with first drain pipe to stop to moisturizing in the water tank 31, lead to the comdenstion water in the water collector 22 outdoor, avoid the water level in the water tank 31 too high. When the liquid level in the water tank 31 detected by the liquid level detecting device is lower than the second liquid level, the switching valve is controlled to communicate the water receiving tray 22 with the water diversion flow passage 40, so that water is continuously supplemented into the water tank 31.

In order to simplify the structure, in a preferred embodiment, as shown in fig. 1 and 6, an overflow 317 is provided on the water tank 31, the air conditioner further includes an overflow passage 50, an inlet end of the overflow passage 50 is connected to the overflow 317, and an outlet end of the overflow passage 50 is located outside the housing 10, so that when water in the water tank 31 rises to the overflow 317, the air conditioner is discharged through the overflow 317 and the overflow passage 50, and thus, a simple structural design can achieve an effect of preventing the water level in the water tank 31 from being excessively high without providing a control part.
