In some examples, the second detecting member 5 may include a distance measuring sensor such as an ultrasonic sensor or an infrared sensor or a radar sensor, and the second detecting member 5 transmits the detected distance between the second detecting member and the water tank 2 to the control unit, and the control unit determines that the water tank 2 is away from the installation position, that is, determines that the water tank 2 is removed from the water tank base 6 when determining that the detected distance exceeds a corresponding threshold according to the detection result, and controls the anion device 3 to be powered off.

In other examples, the second detection member 5 may comprise a second magnetic sensor, and accordingly, the water tank 2 is provided with a second magnet 21 cooperating with the second magnetic sensor. The second magnetic sensor may include a wireless transmitting module, the wireless transmitting module has a normally open reed pipe, and when the distance between the reed pipe and the second magnet 21 exceeds a set value, the second magnetic sensor sends a corresponding signal to the control unit, so that the control unit determines that the water tank 2 is away from the installation position according to the signal and controls the anion device 3 to be powered off. When the distance between the reed switch and the second magnet 21 is smaller than a set value, the water tank 2 is in the installation position.

Optionally, the bottom of the water tank 2 is provided with a mounting seat, and the mounting seat is provided with a water level detection piece; the second magnet 21 is mounted in the mounting seat. So, do benefit to and simplify the water tank 2 structure, do benefit to and reduce the occupation to water tank 2 internal volume.

Optionally, the water level detecting member includes: a floating level gauge 22; the second magnet 21 is connected to a floating part of the floating type liquid level meter 22, so that the floating part can drive the second magnet 21 to move downwards along with the descending of the water level in the water tank 2; when the water level in the water tank 2 is lower than a preset value, the second magnet moves downwards to a lower limit position; the control unit controls the negative ion device 3 to be powered off when the control unit determines that the second magnet 21 moves down to the lower limit position according to the detection result of the second detection piece 5.

It can be understood that: the parts of the air conditioner internal unit that are not described in this embodiment may adopt conventional settings in the art, and this embodiment is not described herein again.

The embodiment also provides an air conditioner, and the air conditioner comprises an air conditioner external unit and an air conditioner internal unit which are connected.

An outdoor unit of an air conditioner generally includes an outdoor heat exchanger. An air conditioner indoor unit generally includes an indoor heat exchanger, a throttle device, and a compressor.

When the air conditioner performs refrigeration work, the compressor compresses a gaseous refrigerant into a high-temperature high-pressure gaseous state, and sends the gaseous refrigerant to the outdoor heat exchanger for cooling, the high-temperature high-pressure gaseous refrigerant is cooled and then becomes a medium-temperature high-pressure liquid refrigerant, the medium-temperature high-pressure liquid refrigerant is throttled and reduced by the throttling device and becomes a low-temperature low-pressure gas-liquid mixture, and the low-temperature low-pressure gas-liquid mixture absorbs heat in air by the indoor heat exchanger and is vaporized into a gaseous state, so that the refrigeration effect is achieved; the gaseous refrigerant returns to the compressor to continue to be compressed, and the circulation is continued to carry out refrigeration.

It should be noted that the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of the present invention, "a plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise.

In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," "secured," and the like are to be construed broadly and can, for example, be fixedly connected, detachably connected, or integrally formed; may be mechanically coupled, may be electrically coupled or may be in communication with each other; they may be directly connected or indirectly connected through intervening media, or they may be connected internally or in any other suitable relationship, unless expressly stated otherwise. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

In the present invention, unless otherwise expressly stated or limited, the first feature "on" or "under" the second feature may be directly contacting the first and second features or indirectly contacting the first and second features through an intermediate. Also, a first feature "on," "over," and "above" a second feature may be directly or diagonally above the second feature, or may simply indicate that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature may be directly under or obliquely under the first feature, or may simply mean that the first feature is at a lesser elevation than the second feature.

In the description above, references to the description of the term "one embodiment," "some embodiments," "an example," "a specific example," or "some examples," etc., mean that a particular feature, structure, material, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of the invention. In this specification, the schematic representations of the terms used above are not necessarily intended to refer to the same embodiment or example. Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples. Furthermore, various embodiments or examples and features of different embodiments or examples described in this specification can be combined and combined by one skilled in the art without contradiction.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
