In one embodiment, the water tank filtering and circulating device is suitable for electric equipment needing to work by using water vapor, such as a steaming oven and the like. As shown in fig. 1, the water tank includes a waste water box 210 and a purified water box 220, the tank filtering and circulating device includes a detecting device 110, a control device 120 and a waste water circulating device 130, the detecting device 110 is disposed on the waste water box 210, the waste water circulating device 130 connects the waste water box 210 and the purified water box 220, and the control device 120 connects the detecting device 110 and the waste water circulating device 130.

The specific value range of the preset conductivity range can also be set according to actual requirements, and the control device 120 obtains the wastewater conductivity detected by the wastewater conductivity detection device and determines whether the wastewater conductivity is within the preset conductivity range. If the wastewater conductivity is within the preset conductivity range, the control device 120 determines that the wastewater belongs to a filterable circulation state, and controls the water pump 132 to start wastewater filtration if it is detected that the stored wastewater data is greater than a preset wastewater filtration threshold when the filtration time is less than or equal to the preset filtration time threshold.

According to the water tank filtering and circulating device of the steam oven and the control method of the water tank filtering and circulating device, the water in the wastewater box is recovered to the water purifying box in time by monitoring the water amount in the wastewater box and intelligently starting the wastewater circulating device, so that the water utilization rate can be increased, and the frequent water changing operation of a user is reduced. When the circulation times reach the time of can getting rid of waste water box internal waste water, the steaming oven automatic suggestion user clears up the operation, avoids waste water to be in the loop filter always. And when the circulation times are not reached and the wastewater conductivity exceeds a safety index, a user is directly reminded to clean the wastewater. In addition, when detecting that the net electrical conductivity after filtering >15, remind the user to change the filter core, increase the water safety, guarantee water tank filtration back quality of water safety to improve user's use and experience.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above-mentioned embodiments only express several embodiments of the present application, and the description thereof is specific and detailed, but not to be understood as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application. Therefore, the protection scope of the present patent shall be subject to the appended claims.
