Further, based on the food processor provided by the above embodiment, the embodiment of the invention also provides a water inlet detection method of the food processor. Fig. 2 is a flowchart of a water inlet detection method of a food processor according to an embodiment of the present invention, and as shown in fig. 2, an execution main body of the water inlet detection method of the food processor according to the embodiment of the present invention may be a main control circuit, and the specific steps thereof may include:
s201: the main control circuit obtains a detection result of the water level detection module, and the detection result is used for indicating whether water exists in the water tank or not.
In this embodiment, whether there is water in the water tank is detected through the water level detection module, and then whether there is water in the water tank is determined by the main control circuit according to the detection result of the water level detection module.
S202: the main control circuit controls the water pump to pump water at a preset water pumping speed according to whether water exists in the water tank or not.
Wherein, the corresponding preset pumping speed is different when water exists in the water tank and no water exists in the water tank.
In this embodiment, when performing water detection or water level detection, a plurality of preset speeds may be set for the water pump. The main control circuit controls the water pump to work at different speeds according to whether water exists in the water tank or not. This embodiment is having anhydrous detection or water level detection time measuring, and the cooperation water pump is with the work of different speeds, no matter whether the water tank has water, and the water pump all can work a period, and when anhydrous when in the water tank like this, the water pump draws water with a default speed, and the water pump can be managed to find time with the water of pipeline to and with the gaseous evacuation of pipeline, prevent the false retrieval that residual water and residual gas lead to. When the water tank adds water again, the water pump draws water with another preset speed, and the water pump can be with the quick suction pipeline of the water in the water tank, prevents that the pipeline internal gas pressure from leading to into water not smooth, influences the testing result.
According to the water inlet detection method of the food processor, when water detection or water level detection is carried out, the water pump is matched to work at different speeds, the water pump can work for a period of time no matter whether the water tank is filled with water or not, residual water and residual gas in a pipeline between the water tank and the water pump can be emptied, so that the influence of the residual water and steam pressure in the pipeline is avoided, and the reliability of the water detection or the water level detection is improved.
In practical application, when detecting whether the water tank has water at present, whether water exists in the pipeline between the water tank and the water pump is mainly detected so as to judge whether the water tank has water. However, when detecting the presence or absence of water in the pipe, there are the following problems: firstly, the water tank is watered again but the pipeline has the residual gas and leads to anhydrous false retrieval, specifically does: when the pipeline does not have water, because there is atmospheric pressure in the pipeline, can lead to the water tank to put into the back again, water can't flow in the pipeline at once to lead to that water level detection module can't in time detect there is the water signal. Secondly, there is not water but there is residual water and leads to having the false retrieval of water in the water tank in the pipeline, specifically does: when the water tank is empty of water, the water level detection module cannot timely detect that the water tank is empty of water due to the influence of residual water in the pipeline.
In order to solve the above problem, on the basis of the above embodiment, in this embodiment, the preset pumping speed may include a first pumping speed and a second pumping speed; whether master control circuit has water control pump to draw water with predetermineeing pumping speed according to having in the water tank, can include:
when water exists in the water tank, the main control circuit controls the water pump to pump water at a first water pumping speed; when no water exists in the water tank, the main control circuit controls the water pump to pump water at a second water pumping speed so as to empty residual water and residual gas in a pipeline between the water tank and the water pump.
In this embodiment, the water pump can be provided with first pumping speed and second pumping speed, and in the water pump working process, when water level detection module detected there is water, master control circuit control water pump used first pumping speed to draw water. When the water level detection module detects that no water exists, the main control circuit controls the water pump to pump water at a second water pumping speed. Like this when anhydrous in the water tank, the water pump still draws water with the second speed of drawing water, and the water pump can be evacuated the residual water of pipeline to and with the residual gas evacuation of pipeline, can avoid having residual water and lead to having the false retrieval of water at the water tank anhydrous but pipeline, and can avoid having residual gas and lead to anhydrous false retrieval again at the water tank water but pipeline. And when the water tank adds water again, the water pump can be with the water pumping in the water tank suction pipeline in first pumping speed, prevent that the residual air in the pipeline leads to the water inflow when the water tank adds water again not smooth.
Wherein, in the water pump work, and steam generator heating, if the water level detection module detects that there is not water in the water tank, master control circuit draws water speed adjustment with the water pump and is the second speed of drawing water to close steam generator.
