The existing washing machine such as a dish washer generally has a storage function, and part of high-end machine types can even replace part of functions of a disinfection cabinet, so that tableware can be stored for a long time, and the trouble that the tableware needs to be transferred after the tableware is washed is avoided. Generally speaking, dish washer comes to control intracavity humidity through hot-blast stoving subassembly, if dry the tableware through hot-blast after washing, if carry out heated air circulation through regularly (chronogenesis + time timing control) under the storage mode, reduce the risk of getting damp again, avoid peculiar smell, bacterial growing etc.. The problems of the hot air drying mode are as follows: firstly, hot air is started to dry at regular intervals (the time sequence is blind), and the hot air drying device cannot adapt to differences and changes brought by different regions, climates and floors; secondly, the regular hot air drying is limited by operations such as power on/off/power plug-in and pull-out, forgetting to set a storage mode, and not knowing how long a set storage period is appropriate (after the storage period is up, a clean storage function needs to be started repeatedly), so that the customer experience is greatly influenced; thirdly, regular hot air drying brings the increase of energy consumption, but drying efficiency is on the low side, and the condition when humidity increases can't be aimed at accurately, and the very big weather of getting damp of humidity can't satisfy stoving demand and condition again. Therefore, the function of intelligently adjusting the humidity in the cavity of the cleaning machine needs to be designed, so that the humidity in the cavity is controlled in a range suitable for storing tableware, energy conservation and emission reduction can be realized to a greater extent, and pain points that the storage mode is forgotten to be set, the set storage period is unknown (the clean storage function needs to be started repeatedly after the storage period is over) and the like due to operations such as power on and off, power plugging and the like are also solved. At present, the humidity of a cavity is generally detected through a humidity sensor, and then the humidity of the cavity is controlled according to a detected signal. If the humidity sensor is arranged in a high-humidity area where air does not flow, the bad phenomena such as accuracy reduction, condensed water collection and the like are easily caused, and therefore a certain air flowing or isolating mechanism is needed to improve the working condition stability and reliability of the humidity sensor.
