With reference to fig. 2, the scale cleaning method according to the embodiment of the present invention employs a sectional cleaning process for the scale characteristics in the steam generating part:
in the scale dissolving stage, the liquid supply mechanism introduces cleaning liquid into the inner cavity of the steam generating part, and the scale in the inner cavity of the steam generating part is dissolved by the cleaning liquid;
in the scale removing stage, the liquid supply mechanism introduces cleaning liquid into the inner cavity of the steam generating part, the steam generating part is heated to vaporize part of the cleaning liquid, and the pressure of the inner cavity of the steam generating part is increased to promote dissolved scale to be discharged out of the inner cavity of the steam generating part along with the cleaning liquid. In addition, compared with the conventional cleaning method, in the scale discharging stage, in the embodiment, as the steam generating part is heated to vaporize part of the cleaning liquid, the inner cavity of the steam generating part is quickly pressurized, and a small amount of cleaning liquid is used for discharging dissolved scale out of the inner cavity of the steam generating part, so that the scale discharging efficiency is improved and the cleaning liquid is saved; and the vaporization of the cleaning liquid also has the effects of disinfection and sterilization, so that the peculiar smell of the cleaning liquid can be removed, and the peculiar smell of the steam output during normal cooking is avoided.
In this embodiment, the main purpose in the scale dissolving stage is to dissolve the water scale, and in order to ensure that the water scale is fully dissolved in the cleaning solution, reasonable cleaning solution temperature (i.e. steam generation temperature) and scale dissolving stage duration need to be set, specifically speaking:
in the scale dissolving stage, the steam generating part is heated to a first preset temperature and is kept, and the first preset temperature is 97-99 ℃, such as 97 ℃, 98 ℃, 99 ℃ and the like. The high-temperature heating can accelerate the reaction speed of the cleaning liquid and the water scale, the scale dissolving effect is better, the first preset temperature is set to be 97-99 ℃, the water scale is quickly dissolved by the cleaning liquid under the condition of no boiling, and the cleaning liquid has the functions of sterilization and disinfection.
The duration of the scale dissolving stage is 40-70 min. The main purpose of the scale dissolving stage is to dissolve the scale, in order to ensure that the scale is fully dissolved in the cleaning solution, in addition to heating the cleaning solution at a high temperature, the duration of the scale dissolving stage can be increased, that is, the reaction time between the cleaning solution and the scale is increased, and for the case of severe scale formation, more scale can be dissolved by soaking for a long time, but the overall cleaning time and energy consumption are also prolonged, so that the duration of the scale dissolving stage is set to 40min to 70min, such as 40min, 50min, 55min, 60min, 70min, and the like, and the adjustment can be specifically performed according to a first preset temperature and the scale formation severity.
In the scale removing stage, the steam generating part is heated to a second preset temperature and kept, and the second preset temperature is set to be 105-110 ℃. The purpose of setting this temperature is: the steam generating part is heated to a temperature higher than the boiling point of water, so that part of the cleaning liquid is vaporized in a short time, a certain amount of cleaning liquid is reserved in the inner cavity of the steam generating part, and the dissolved scale is sprayed out along with the cleaning liquid from the inner cavity of the steam generating part under the combined action of air pressure kinetic energy and water flow energy.
In the scale removing stage, the liquid supply mechanism introduces cleaning liquid into the inner cavity of the steam generating part at a third flow rate W3, wherein the third flow rate W3 is 0.8L/min-1.5L/min, and L is the volume of the inner cavity of the steam generating part. It can be understood that: the flow of the water pump is adjusted by the power of the water pump, the larger the power is, the larger the flow of the water pump is, the more cleaning liquid is introduced into the inner cavity of the steam generating part in unit time is, correspondingly, the larger the working noise of the water pump is, if the third flow W3 is too small, after part of the cleaning liquid is vaporized, the rest cleaning liquid cannot carry more water scales, and the scale removing effect is weakened; if the third flow rate W3 is too high, the steam generating part also needs to increase the heating power to maintain the second preset temperature, which increases the energy consumption and noise, so that in this embodiment, the third flow rate W3 is set to 0.8L/min to 1.5L/min, which not only satisfies the cleaning liquid amount required for removing the scale, but also effectively controls the energy consumption and noise of the steam generating part and the liquid supply mechanism. In practical applications, the third flow rate W3 may be adjusted according to the second preset temperature and the scaling severity, for example, 0.8L/min, 1L/min, 1.2L/min, 1.5L/min, etc.
Because the scale is discharged by utilizing the vaporization pressurization of the cleaning liquid in the scale removal stage, a large amount of cleaning liquid is consumed for long-time operation, but the scale removal effect is not obviously increased, so the duration of the scale removal stage is far shorter than that of the scale dissolution stage, is usually set to be 3min to 10min, such as 3min, 5min, 7min, 8min, 10min and the like, and can be specifically adjusted according to the third flow W3 and the scale severity.
The cleaning liquid used in the embodiment is a mixed solution of water and citric acid, and the citric acid is food-grade citric acid generally, so that the prepared cleaning liquid is safe and sanitary and cannot damage a steam generation part; citric acid can be quickly dissolved by mixing with water, so that the dissolving effect of the citric acid is fully exerted, and the scale in the inner cavity of the steam generating part can be quickly decomposed. Of course, the cleaning solution used in the present invention is not limited to citric acid solution, and other detergent may be used.
If the scale formation is serious, according to the scale cleaning method of the embodiment, the scale dissolving stage and the scale removing stage can be performed at least twice in a cycle to increase the scale removing effect.

a second scale dissolving step, wherein the liquid supply mechanism intermittently introduces cleaning liquid into the inner cavity of the steam generating part at a second flow rate W2; wherein; in the second scale dissolving step, if the second flow rate W2 is too large, the introduced cleaning solution is discharged without enough time to participate in the reaction, resulting in waste, therefore, the second flow rate W2 is smaller than the first flow rate W1, and is set to 0.3L/min to 0.7L/min in this embodiment, cleaning liquid is intermittently introduced into the inner cavity of the steam generating part at a relatively small flow rate, for example, a water pump works for 1min and pauses for 2min, the above steps are repeated, new cleaning solution is intermittently introduced into the inner cavity of the steam generating part, so that the cleaning solution participating in the scale reaction is intermittently discharged out of the inner cavity of the steam generating part, under the condition of ensuring that the inner cavity of the steam generating part is filled with the cleaning liquid, the cleaning liquid participating in the reaction is intermittently replaced by the new cleaning liquid, so that the scale dissolving effect is prevented from being reduced due to long-time reaction of the cleaning liquid, the scale is fully dissolved, and the waste of the cleaning liquid is avoided; in addition, in the second scale dissolving step, dissolved scale is intermittently discharged out of the inner cavity of the steam generating part along with the cleaning liquid, and the dissolved scale is discharged out of the inner cavity of the steam generating part in batches in the scale dissolving stage, so that the scale discharging pressure in the scale discharging stage is relieved, the problem that the scale is not smooth or even blocked due to the concentrated discharge of the scale in the scale discharging stage is avoided, and the smooth scale discharging in the scale discharging stage is facilitated.
