preferably, a water pump 5 is arranged on the water inlet pipe 2, and the controller is in signal connection with the water pump 5. Specifically, when the steam generator 1 is started, the water pump 5 is controlled to operate to add water into the steam generator 1, or when the water flow sensor 3 detects that the water inflow of the steam generator 1 reaches the target water inflow, the water pump 5 is controlled to stop operating to stop adding water into the steam generator 1.

When the controller judges that the steam generating device 1 triggers the scale prompting condition, the controller controls the prompting device to start to work so as to send a prompting signal to a user, and the user is prompted to clean the scale in the steam generating device 1 in time.
Example two: as shown in fig. 1, 2 and 3, the present embodiment provides a scale detection method for a steam cooking apparatus, applied to the scale detection apparatus according to the first embodiment, the scale detection method including:
adding water into the steam generating device 1, judging whether the water inflow of the steam generating device 1 reaches the target water inflow W or not, and detecting the initial water temperature T1, specifically, controlling the water pump 5 to act by the controller to add water into the conventional steam generating device 1, and detecting the initial water temperature T1 in the steam generating device 1 through the first temperature sensor 4;
If the water inflow of the steam generating device 1 reaches the target water inflow W, stopping adding water into the steam generating device 1 and starting the steam generating device 1, specifically, the target water inflow W is stored in a controller or a memory connected with the controller in advance, the controller can realize the purpose of stopping adding water into the steam generating device 1 by controlling a water pump 5 to stop working, and meanwhile, the controller controls a heating pipe to heat water entering the steam generating device 1; if the water inflow of the steam generating device 1 does not reach the target water inflow W, controlling the water pump 5 to continuously work to add water into the conventional steam generating device 1;
Judging whether the water temperature in the steam generating device 1 reaches a target water temperature T2, specifically, the target water temperature T2 is stored in the controller in advance or stored in a memory connected with the controller;
if the water temperature in the steam generating device 1 reaches the target water temperature T2, recording or calculating the working time T of the steam generating device 1, namely recording or calculating the time for the steam generating device 1 to heat the water in the steam generating device 1 from the initial water temperature T1 to the target water temperature T2; if the water temperature in the steam generating device 1 does not reach the target water temperature T2, controlling the steam generating device 1 to continue working and continuously judging whether the water temperature in the steam generating device 1 reaches the target water temperature T2;
Judging whether the working time T of the steam generating device 1 is greater than a first time threshold TS1, if the working time T of the steam generating device 1 is greater than a first time threshold TS1, judging that the steam generating device 1 triggers a scale prompting condition, and prompting a user to clean scale at the moment; if the operating time T of the steam generator 1 is less than the first time threshold TS1, it is determined that the steam generator 1 does not trigger the scale presentation condition. Specifically, the first time threshold TS1 may be obtained on the premise of measuring the initial water temperature T1 according to the mapping relationship between the initial water temperature T1 and the first time threshold TS1, and then the relationship between the operating time T and the first time threshold TS1 may be determined.
The incrustation scale detection method of this embodiment, whether its detection that can be accurate needs to clear up the incrustation scale in steam generator 1 to the suggestion user in time clears up the incrustation scale, does benefit to promotion user's use and experiences.
in this embodiment, the first time threshold TS1 is specifically: the time required for the steam generating device 1 to heat the target water inflow W from the initial water temperature T1 to the target water temperature T2 under the preset conditions. Wherein the preset conditions are as follows: the state of the steam generator 1 during operation when the steam generator 1 is not operating and the amount of scale present is small and the scale needs to be cleaned.
according to the relation that the input electric energy and the output heat energy are equal in energy, theoretically P T is Q1, wherein P is the rated power of a heating tube of the steam generating device, and T is the heating time of the steam generating device.
Since Q1 is C m Δ T, where C is the specific heat of water, m is the mass of water, and Δ T is the temperature difference between the heated temperature T2 of water and the initial water temperature T1. In fact, due to the influence of heat conducting materials, scales and other factors, the above formula should be P × T × K — Q1, where K is the heat transfer efficiency coefficient, and generally, the more scales in the steam generator, the smaller the K value.
Since the rated power of the heating tube of the steam generator is fixed, the water temperature rises from a certain initial water temperature T1 to the target water temperature T2, and the required energy is fixed when the water amount is fixed. The heat transfer efficiency is highest when the material of the steam generating device is fixed and there is no scale in the steam generating device to obstruct the heat transfer, and the K value is the largest at this time. After the incrustation is accumulated in the steam generating device, the energy exchange speed between the heating pipe and water is reduced, and the K value is reduced, namely under the same condition, the steam generating device heats the same mass of water from the initial water temperature T1 to the same target water temperature T2, and needs longer heating time, so that the relation between the incrustation generation condition and the heating time can be established, and the incrustation generation degree in the steam generating device can be obtained by comparing the actual heating time of the steam generating device with the first time threshold TS1 under the preset condition. Wherein, when the actual heating time of steam generator is greater than first time threshold TS1, then judge that steam generator triggers incrustation scale suggestion condition, will indicate the user to need to clear up the incrustation scale this moment. In this embodiment, the controller may prompt in a voice or display manner.
Further, a mapping relationship between the different initial water temperatures T1 and the first time threshold TS1 is established according to the heating time required for the steam generating device 1 to heat the target water inflow W from the different initial water temperatures T1 to the target water temperature T2. When water is added into the steam generating device 1, the initial water temperature T1 is detected, at this time, the controller can find, calculate or judge the first time threshold TS1 corresponding to the initial water temperature T1 according to the mapping relation pre-stored in the controller or in the memory connected with the controller, when the water temperature in the steam generating device 1 reaches the target water temperature T2, the working time T of the steam generating device 1 is recorded or calculated, and the working time T of the steam generating device 1 is compared with the first time threshold TS1 to judge that the scale prompting condition is triggered by the steam generating device 1.
In the present embodiment, after the steam generator 1 is started, it is determined whether the water in the steam generator 1 is boiling;
if the water in the steam generating device 1 reaches boiling, accumulating the boiling time of the water, specifically, accumulating and calculating the time of the water in the boiling state; if the water in the steam generating device 1 does not reach boiling, controlling the steam generating device 1 to continuously work and continuously judging whether the water in the steam generating device 1 reaches boiling;
and judging whether the steam generating device 1 triggers a scale prompting condition or not according to the working time T of the steam generating device 1 and the boiling accumulated time TA of the water. If the water scale is met, the steam generating device 1 is judged to trigger the water scale prompting condition, and at the moment, a user is prompted to clean the water scale.
The accuracy of detection, judgement incrustation scale production condition can be promoted to a certain extent through above-mentioned detection, judgement step to this embodiment, is favorable to the suggestion user in time clear up the incrustation scale and promote user's use experience.
in addition, foretell detection, judgement step are also comparatively simple, and detection that can be accurate whether need clear up the incrustation scale in the steam generator 1 to the suggestion user in time clears up the incrustation scale, does benefit to the use experience that promotes the user.
Further, the step of determining whether the water in the steam generating device 1 reaches boiling specifically comprises:
If the water temperature in the steam generating device 1 reaches 99 ℃, judging that the water in the steam generating device 1 reaches boiling, and generally, judging that the water in the steam generating device 1 reaches boiling when the water temperature reaches 99 ℃;
Or, in a first preset time period in the working state of the steam generating device 1, if the water temperature in the steam generating device 1 is maintained above 90 ℃ and the temperature rise is smaller than a first preset temperature rise range, the water in the steam generating device 1 is judged to be boiling, so that the situation that whether the water in the steam generating device 1 is boiling cannot be judged when the water temperature in some plateau areas cannot reach the boiling temperature in plain areas can be avoided, and the accuracy of detection and judgment can be improved;
Or, if the temperature rise of the temperature in the cavity 6 in the second preset time period is larger than the second preset temperature rise range, it is determined that the water in the steam generating device 1 reaches boiling. Specifically, the temperature inside the chamber 6 is detected by the second temperature sensor 8 provided on the chamber 6. Because, when the water in the steam generating device 1 reaches the boiling, the water in the steam generating device 1 will become high-temperature steam and be input into the cavity 6, and then the temperature in the cavity 6 rises, if the temperature rise of the temperature in the cavity 6 in the second preset time period is greater than the second preset temperature rise range, the water in the steam generating device 1 can be judged to reach the boiling, and therefore the accuracy of judging whether the water in the steam generating device 1 reaches the boiling can be further improved, and the accuracy and the reliability of the detection method are favorably improved.
In this embodiment, the step of determining whether the steam generator triggers the scale presentation condition according to the operating time T of the steam generator 1 and the cumulative boiling time TA of the water is specifically as follows:
If the cumulative boiling time TA of the water is greater than the second time threshold TS2 and the operating time T of the steam generating device 1 is greater than K × the first time threshold TS1, specifically: TA is more than or equal to TS2, and T is more than or equal to KxTS 1, the steam generator 1 is judged to trigger scale prompting conditions. If the above condition is not satisfied, it is determined that the steam generator 1 does not trigger the scale presentation condition. The step is reasonable and ingenious in design, and the accuracy and the reliability of judging whether the scale in the steam generating device 1 meets the prompt condition by the scale detecting device can be improved.
In this embodiment, K is a scale-to-boiling cumulative time proportionality coefficient, and preferably, K is 0.5 to 1. In general, when the water is in the boiling state, the time required for heating the same mass of water is shorter than the time when the water is not in the boiling state, so that after a plurality of experiments and tests, K is preferably 0.5 to 1.
What has been described above are merely some embodiments of the present invention. It will be apparent to those skilled in the art that various changes and modifications can be made without departing from the inventive concept thereof, and these changes and modifications can be made without departing from the spirit and scope of the invention.
