Because the water amount in the water storage box 120 is added in advance or is left after using part of water before, when the water level/amount/water supply time left in the water storage box 120 cannot meet the requirement of the steam generation system 400 on the upcoming work, the steam generation system 400 is set to stop working and/or alarm at the moment, so that the situation that the steam generation system 400 burns dry is avoided, and a user can be prompted to add water at the same time to meet the requirement of the next work of the steam generation system 400.

It can be understood that the preset water supply information and the water supply information in the water storage box 120 are parameters corresponding to each other, for example, the adopted water supply information in the water storage box 120 refers to the current water level in the water storage box 120, and the preset water supply information corresponds to a preset water level value. When the user sets the sterilization for one hour, the preset water level value can be calculated according to the amount of water required by the steam generation system 400 to work for one hour by combining the size parameter of the water storage box 120, and then compared with the current water level value of the water storage box 120.

According to the technical scheme, the main control board of the steam disinfection cabinet can receive the water supply information which is currently supplied to the steam generation system 400 in the water storage box 120 in real time by utilizing the liquid level detector 130 which can be connected with and detect the liquid level change in the water storage box 120, and further can accurately judge whether the water energy in the water storage box 120 currently meets the work of the steam generation system 400 according to the current work or the work to be carried out of the steam system, so that the water box assembly 100 can accurately supply water to the steam system, the dry burning condition of the steam generation system 400 is avoided, and the work safety of the steam disinfection cabinet is improved.

Further, in this scheme, the step of obtaining the current water supply information value in the water storage box 120 further includes:

In the present embodiment, when the steam sterilizing cabinet is in operation, the steam generating system 400 generates a constant steam speed, so that the water consumption of the steam generating system 400 per unit time is correspondingly constant. In another embodiment, the steam sterilizing cabinet can be used for users to select different steam generating speeds, for example, the steam sterilizing cabinet can generate different steam generating speeds by setting a sterilizing mode, sterilizing time or according to different objects to be sterilized; and generating the corresponding preset water supply information by the steam generation speed value and the steam generation time desired by the user. For example, according to the steam generation speed value and the steam generation time desired by the user, the total amount of steam desired by the user can be obtained, the amount of water required by the steam generation system 400 can be obtained according to the total amount of steam, and the corresponding preset water level value can be obtained according to the water level value.

In another embodiment, the steam generation speed of the steam generating system 400 is constant, and the user can set the working time of the steam generating system 400 to obtain the desired disinfection effect, for example, when the steam disinfection cabinet is used to disinfect a large number of dishes, the user sets a disinfection hour, and when the number of dishes to be disinfected is small, the user sets a disinfection half hour, it can be understood that the total steam amount desired by the user can also be obtained according to the steam generation speed and the steam generation time desired by the user, and thus the preset water supply information (the water supply value of the water storage box 120 or the liquid level value of the water storage box 120 corresponding to the total steam amount, etc.) can be obtained

Based on the above embodiment, when the water supply information is the water supply time period; the step of obtaining the current water supply information value in the water storage box 120 is:

acquiring the current residual water amount in the water storage box 120;

generating a preset water consumption per unit time of the steam generation system 400 according to the steam generation speed value expected by the user;

and calculating the residual water supply time of the water storage box 120 according to the residual water amount and the preset water consumption of the steam generation system 400 in unit time.

It should be noted that the water consumption of the steam generating system 400 per unit time may be understood as the water consumption required by the steam generating system 400 within 1 second of operation, and it may be understood that the water consumption of the steam generating system 400 per unit time corresponds to the steam generation amount, so that the remaining water supply time of the water storage box 120 can be obtained by dividing the remaining water consumption by the preset water consumption of the steam generating system 400 per unit time. At this time, the preset water supply information corresponds to a preset water supply time, and the preset water supply time may be a certain value or different according to the setting of the user according to different types of steam disinfection cabinets, which is specifically referred to in the above embodiment.

In another embodiment, also in the case that the water supply information is a water supply time period; the step of obtaining the current water supply information value in the water storage box 120 is:

acquiring the residual water amount or water level value in the current water storage box 120;

and calculating the residual water supply time of the water storage box 120 according to a table of the corresponding relationship between the preset water level and the residual water supply time of the water storage box 120 or a table of the corresponding relationship between the water amount and the residual water supply time of the water storage box 120.

The table of the corresponding relationship between the preset water level and the remaining water supply time of the water storage box 120, or the table of the corresponding relationship between the water amount and the remaining water supply time of the water storage box 120 may be obtained according to the water consumption amount per unit time of the steam generation system 400, the shape and the size parameters in the water storage box 120, the preset water level and the remaining water supply time of the water storage box 120 in the table are all discrete, and the corresponding remaining water supply time may be found according to the current remaining water level in the water storage box 120 and the water level value closest thereto in the table as a reference.

In an embodiment, the time length of the single water supply period of the steam generating system 400 is a fixed value, and the step of comparing the water supply information value in the water storage box 120 with the preset water supply information value includes:

when the water supply information value in the water storage box 120 is greater than the preset water supply information value, calculating the remaining water supply period of the water storage box 120 according to the remaining water supply period of the water storage box 120 and the period used for a single water supply period of the steam generation system 400;

and controlling the water storage box 120 to supply water to the steam generation system 400 during the remaining water supply period.

It is understood that the remaining water supply period of the water storage box 120 is obtained by dividing the remaining water supply period of the water storage box 120 by the time period for a single water supply period of the steam generation system 400. This embodiment can be used in the case that the time length for each operation cycle of the steam sterilizing cabinet (steam generating system 400) is the same as the steam generating speed, so that the user can more intuitively know the remaining water supply cycle of the water storage box 120.

Based on the above embodiment, the step of obtaining the current amount of water remaining in the water storage box 120 includes:

acquiring the current liquid level value of the water storage box 120;

and obtaining the residual water amount in the current water storage box 120 according to the level value of the current water storage box 120 and the preset size parameter of the cavity in the water storage box 120.
