Problems solved by technology

[0008] However, in the drying machine of the above-mentioned prior art, when the water level detected by the above-mentioned electrode sensor is above a certain water level as a reference value, the pump is driven regardless of the amount of dehumidified water. Regardless of the type of condensed water, in the case of condensed water close to distilled water, the above condensed water will not be detected
[0009] Moreover, in the drying machine of the prior art, the output voltage of the above-mentioned electrode sensor changes because the characteristics of the components in the water level detection device are not considered.

Abstract

The invention relates to a water level detecting device and method for a dryer, which solve the problems that when the condensed water near to the distilled water is collected, it is impossible to detect the electrode sensor in a way of driving irrelevant to the quantity of the dehumidification water; the costuming is damaged in a way of driving based on a humidity detected by an electrode sensor and irrelevant to the costuming of the drying articles; and there is an error in judging the water level owing to not considering the characteristic of the detection unit. Therefore, the invention accurately detects the water level.

Description

technical field [0001] The invention relates to a water level detection device of a dryer and a detection method thereof. In the present invention, the saturation characteristics of circuit elements or the characteristics of condensed water in the water level detection device will be considered, and the water level can be measured more accurately. Detect operation. Background technique [0002] In general, a clothes dryer is a device that blows hot air generated by a heater into a drum, absorbs moisture of an object to be dried, and performs a drying operation on the object to be dried. The above-mentioned clothes dryers can be roughly classified into exhaust-type clothes dryers and condensation-type clothes dryers according to different ways of treating humid air generated when drying objects by absorbing moisture. [0003] The exhaust type clothes dryer adopts a method of exhausting the humid air exhausted from the drum to the outside of the dryer, but it is necessary to ...
