[0024] It should be noted that, unless otherwise specified, the embodiments and technical features in the embodiments of this application can be combined with each other, and the detailed descriptions in the specific implementation should be understood as explanations of the purpose of this application and should not be regarded as undue limitations on this application.

[0025] In the description of the embodiments of this application, it should be noted that the terms "top," "bottom," and "height direction," etc., indicate the orientation or positional relationship based on the appendix. Figure 1 The orientations or positional relationships shown are for the convenience of describing the embodiments of this application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the embodiments of this application. The application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0026] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0027] This application provides an air conditioner; please refer to [link / reference]. Figure 1 and Figure 2 The air conditioner includes a housing 10, a heat exchanger, a drip tray, a water pump 20, and a water level monitoring switch 30. The housing 10 includes a first side plate 11. The heat exchanger is disposed within the housing 10. The drip tray is disposed below the heat exchanger and is used to collect condensate flowing down from the heat exchanger. The water pump 20 is connected to the first side plate 11. The water level monitoring switch 30 is disposed on the water pump 20 and is used to detect the water level in the drip tray.

[0028] Air conditioners achieve cooling or heating through a compressor, condenser, expansion valve, and evaporator.

[0029] When an air conditioner is in cooling mode, condensation may form on the surface of the heat exchanger as airflow passes over it. By placing a drip tray below the heat exchanger, the drip tray can collect the condensation flowing down from the heat exchanger, thus improving the condensation flow and enhancing the user experience.

[0030] The fact that a drip tray is used to collect condensate from the heat exchanger means that, in addition to collecting condensate from the heat exchanger, the drip tray can also be used to collect condensate from other components of the air conditioner besides the heat exchanger.

[0031] Referring to Figure 1 and Figure 2 The water pump 20 is connected to the first side plate 11, and is configured to draw condensed water in the water tray out of the air conditioner when the water pump 20 is started.

[0032] The water pump 20 has a water inlet and a water outlet, and a water outlet pipeline is arranged at the water outlet.

[0033] Exemplarily, the water pump 20 is located above the water tray, so that the water inlet of the water pump 20 faces the water tray, and the water inlet of the water pump 20 is in contact with the condensed water in the water tray. When the water pump 20 is working, the water inlet of the water pump 20 can draw the condensed water collected in the water tray.

[0034] The water level monitoring switch 30 is arranged to detect the water level in the water tray. When the water level in the water tray reaches a preset water level, the water level monitoring switch 30 is actuated and sends a detection signal to the control unit, and the control unit controls the water pump 20 to start and drain water. In this way, the working frequency of the water pump 20 can be reduced.

[0035] Exemplarily, the water level monitoring switch 30 can be a float switch.

[0036] Exemplarily, the water level monitoring switch 30 can be in a normally closed state, and once the water level in the water tray reaches the preset water level, the water level monitoring switch 30 is opened, i.e., in an open state.

[0037] Of course, the water level monitoring switch 30 can be in a normally open state, and once the water level in the water tray reaches the preset water level, the water level monitoring switch 30 is closed, i.e., in a closed state.

During use, the air conditioner can generate certain condensate water, the water collecting tray is used to collect the condensate water, and the water level monitoring switch 30 is used to detect the water level height in the water collecting tray. When the water level height in the water collecting tray reaches a set height, the water pump 20 is started to suck the condensate water in the water collecting tray, so that the working frequency of the water pump 20 can be reduced. The water pump 20 is connected to the first side plate 11 of the shell 10, and the water level monitoring switch 30 is arranged on the water pump 20, so that the water level monitoring switch 30 is fixed, the water level monitoring switch 30 does not need to be connected to the shell 10 through other adapters, the number of parts is reduced, the assembly efficiency is improved, and the cost is reduced.
