Embodiment 1

[0038] see figure 1 , which is a schematic structural diagram of a water level monitoring device provided in Embodiment 1 of the present invention. The water level monitoring device includes, for example: a water receiving tray 210, a first monitoring electrode 13a and a second monitoring electrode 13b. The first monitoring electrode 13 a and the second monitoring electrode 13 b are suspended in the water receiving tray 210 , and a return electrode 19 is also provided at the bottom of the water receiving tray 210 .

[0039] In a specific embodiment, when the water level of the condensed water collected in the water receiving tray 210 reaches the preset warning water level, the circuit between the first monitoring electrode 13a and / or the second monitoring electrode 13b and the return electrode 19 is conducted. , processed in the controller of the air conditioner to form an early warning signal.

[0040]Further, the first monitoring electrode 13a and the second monitoring ele...

Embodiment 2

[0063] see image 3 , which is a schematic diagram of the second circuit structure 120 of the water level monitoring device provided in Embodiment 2 of the present invention. The difference from the first embodiment above is that the second circuit structure 120 in this embodiment utilizes the Vref1 pin and the Vref2 pin in the triode to electrically connect with the condensed water in the water tray 210 to form an electrical signal and send it to The electrical signal receiving end of the controller 20 . That is, when the Vref1 pin is electrically connected to the condensed water, it can be considered that the condensed water in the water receiving tray 210 has reached the warning water level at this time; otherwise, it can be considered that the condensed water has not reached the warning water level at this time.

[0064] In a specific embodiment, the triode includes, for example, a first triode 71 and a second triode 72, wherein the output end of the first triode 71 is el...

Embodiment 3

[0070] Embodiment 4 of the present invention provides an air conditioner, the air conditioner includes, for example, the water level monitoring device as described in Embodiment 1 or Embodiment 2, that is, includes the first circuit structure 110 in Embodiment 1 or the embodiment Second circuit structure 120 in the second.

Abstract

The invention provides a water level monitoring device, an air conditioner and a water level monitoring method of the air conditioner. The water level monitoring device comprises a water pan, a first monitoring electrode and a second monitoring electrode; the first monitoring electrode and the second monitoring electrode are arranged in the water pan in a suspended mode; a loop electrode is further arranged at the bottom of the water pan; and when the water level rises to the early warning water level, the first monitoring electrode and / or the second monitoring electrode are / is connected with the loop electrode to generate an early warning signal. The problem that specific water level information of condensate water in the water pan cannot be monitored, and consequently early warning of the water level information cannot be effectively achieved is solved.

Description

technical field [0001] The invention relates to the technical field, in particular to a water level monitoring device, an air conditioner and a water level monitoring method for the air conditioner. Background technique [0002] During the working process of the air conditioner, especially in the cooling state, the evaporator of the internal unit will produce condensed water, and the water receiving pan will collect the condensed water and discharge it from the drain. However, during the long-term use of the air conditioner, dust or mosquitoes will be generated inside the air conditioner. Over time, it is easy to cause blockage of the drain pipe, that is, to cause the condensed water in the water tray to overflow, and finally cause the air conditioner to leak, thereby causing property loss. cause user complaints. Contents of the invention [0003] The problem solved by the invention is that it is impossible to monitor the specific water level information of the condensed ...
