Problems solved by technology

[0003] However, the problem with the related technology is that the water on the chassis is often not drained at the end of defrosting, so that when the condenser frosts again and reaches the thickness of contacting the water on the chassis, the water on the chassis will c

Embodiment Construction

[0042] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0043] The structure of the air conditioner is briefly introduced below.

[0044] The air conditioner may include an indoor unit and an outdoor unit. The outdoor unit may include a compressor and an outdoor heat exchanger. The outdoor heat exchanger includes cooling fins and copper tubes. Medium, when the compressor connected to the copper pipe does work, the heat transfer medium in the copper pipe is compressed into high-temperature and high-pressure steam, which heats up the air in the indoor unit of the air conditioner connect...

Abstract

The invention discloses an air conditioner and a bottom disc freezing detection device and method thereof. The bottom disc freezing detection device comprises a freezing detection module and a capacitance detection module. The freezing detection module comprises at least one freezing induction assembly, each freezing induction assembly is arranged on a bottom disc of the air conditioner, and when each freezing induction assembly detects freezing of the bottom disc of the air conditioner, the capacitance value of the freezing detection module changes. The capacitance detection module is connected with the freezing detection module and generates a freezing detection signal by detecting the capacitance value of the freezing detection module, and therefore the freezing degree of the bottom disc of an outdoor unit can be accurately detected, the situation that the heating capacity of the air conditioner is reduced due to the too large freezing thickness is avoided, the work efficiency of the air conditioner is ensured, and use safety of an axial flow fan is guaranteed.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner chassis icing detection device, an air conditioner with the device and an air conditioner chassis icing detection method. Background technique [0002] In the related art, the condenser of the air conditioner tends to precipitate moisture when the outdoor temperature is low in winter, and the precipitated moisture adheres to the surface of the condenser coil to form a frost layer. With the formation of the frost layer, the heating capacity of the air conditioner decreases. When the defrosting condition of the air conditioner is reached, the air conditioner starts the defrosting mode to turn the frost layer on the condenser into water, and the water flows along the condenser. onto the pan and drain through the drain hole in the pan. [0003] However, the problem with the related technology is that the water on the chassis is often not drained at the en...
