[0053] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0054] A steam oven can also be called a steam box, a steamer, etc., which will not be discussed here.

[0055] Figure 1 FIG. 1 is a schematic diagram of the structure of a steam oven according to an embodiment of the present invention. Figure 1 As shown, the steam oven comprises a water pump 110, a water tank 120, a steam generator 130 and a waste water box 140. When the steam oven is cooking, the water pump 110 pumps water from the water tank 120 to the steam generator 130, and the steam generator 130 heats the water into steam, which enters the steam oven. The steam overflowing from the internal cavity of the steam oven flows into the waste water box 140 through the exhaust pipe after being cooled and condensed. The waste water box 140 can be removed to facilitate emptying the condensed water therein.

[0056] The method for treating condensed water from a steam oven of the present invention is applied to the above-mentioned steam oven, or can be applied to other cooking appliances with similar or similar principles and functions.

[0057] Figure 2 The flowchart of the method for treating condensed water from a steam oven according to an embodiment of the present invention is shown. Figure 2 As shown, the method for treating condensed water from a steam oven comprises:

[0058] Step 210, receiving a start command;

[0059] Step 220, obtaining a first idle capacity in a waste water box of the steam oven;

[0060] Step 230, obtaining the volume of condensed water generated in the current cooking program according to the start command;

[0061] Step 240, determining whether the condensed water volume is greater than or equal to the first idle capacity;

[0062] Step 250: If the condensed water volume is greater than or equal to the first free capacity, a condensed water clearing alarm is generated.

[0063] The method of the embodiment of the present invention, after receiving the start command, will determine whether the volume of condensed water generated in the current cooking program is greater than the first free capacity in the waste water box. If the volume of condensed water is greater than or equal to the first free capacity in the waste water box, it means that after executing the current cooking program, the condensed water in the waste water box will overflow before the end of the current cooking program. Therefore, the method of the embodiment of the present invention will generate an alarm for clearing condensed water when the condensed water in the waste water box may overflow, so that the user can empty the waste water box in advance before executing the current cooking program, thereby avoiding overflow of condensed water during the cooking process, and avoiding interrupting the cooking process before the end of cooking to empty the waste water box, thereby avoiding contamination of the desktop due to overflowing condensed water, and avoiding adverse effects of interrupting the cooking process on the cooked product, thereby improving the user experience.

[0064] In the embodiment of the present invention, in step 230, obtaining the volume of condensed water generated in the current cooking program according to the start command includes:

[0065] According to the start command, obtaining a recipe in the current cooking program;

[0066] According to the recipe, the volume of condensed water generated in the current cooking procedure is obtained.

[0067] In an embodiment of the present invention, different recipes may generate different volumes of condensed water. For example, the volumes of condensed water generated by steaming sweet potatoes with a relatively low water content and steaming and then baking corn with a relatively high water content are different. Therefore, in an embodiment of the present invention, different recipes correspond to different volumes of condensed water.

[0068] In the embodiment of the present invention, obtaining the volume of condensed water generated in the current cooking process according to the recipe includes:

[0069] According to the recipe, obtaining a first steam curve;

[0070] Obtaining the cooking time of the current cooking program;

[0071] The volume of condensed water generated in the current cooking procedure is acquired according to the first steam curve and the cooking time.

[0072] In the embodiment of the present invention, if the first steam curve is a fixed value straight line, obtaining the volume of condensed water generated in the current cooking process according to the first steam curve and the cooking time includes:

[0073] The first steam curve is multiplied by the cooking time to obtain the volume of condensed water generated in the current cooking program.

[0074] In an embodiment of the present invention, the first steam curve can be used to describe the steam rate / steam volume generated in different time periods corresponding to a recipe. For example, corn is steamed first and then roasted. In the first stage, the steaming stage with large steam, the steam generator works and the steam rate generated is 2. In the second stage, the corn roasting stage, the steam generator stops working, and the steam rate generated is completely provided by the corn itself, which may be 0.2.

[0075] In other embodiments of the present invention, in order to simplify the calculation process, the first steam curve can also be set as a fixed value straight line, which can be called the first steam coefficient. That is, for a recipe, the first steam curve is directly calculated according to the first steam coefficient. For example, the first steam coefficient is the same for a 20-minute recipe and a 50-minute recipe, but the cooking time of the recipe is different, and the condensed water produced is also different. Therefore, in the embodiment of the present invention, the first steam coefficient and the cooking time can be multiplied to obtain the condensed water volume.

[0076] In the embodiment of the present invention, obtaining the volume of condensed water generated in the current cooking process according to the recipe includes:

[0077] According to the recipe, obtaining a second steam curve;

[0078] Get the weight of the food in the steam oven;

[0079] The volume of condensed water generated in the current cooking program is obtained according to the second steam curve and the weight of the food in the steam oven.

[0080] In the embodiment of the present invention, if the second steam curve is a fixed value straight line, obtaining the volume of condensed water generated in the current cooking program according to the second steam curve and the weight of the food in the steam oven includes:

[0081] The second steam curve is multiplied by the weight of the food in the steam oven to obtain the volume of condensed water generated in the current cooking program.

[0082] In the embodiment of the present invention, the second steam curve can be used to describe the steam rate / steam volume etc. generated by the weight of different ingredients corresponding to the recipe. The second steam curve can be applicable to ingredients with a high water content.

[0083] Since the water content of food is high, part or a large part of the condensed water produced by the steam oven comes from the food itself, in addition to that produced by the steam generator. Therefore, the weight of the food will have a greater impact on the condensed water produced during the cooking process.

[0084] In other embodiments of the present invention, in order to simplify the calculation process, the second steam curve can also be set as a fixed value straight line, which becomes the second steam coefficient. That is, for a recipe, the second steam curve is directly calculated according to the second steam coefficient. For example, the second steam coefficient may be the same for 0.5 kg of food and 2 kg of food, but because the weight of the food is different, the condensed water produced is also different. Therefore, in the embodiment of the present invention, the second steam coefficient can be multiplied by the weight of the cooking food to obtain the condensed water volume.

[0085] In the embodiment of the present invention, obtaining the volume of condensed water generated in the current cooking process according to the recipe includes:

[0086] According to the recipe, obtaining a third steam curve;

[0087] Get the cooking time of the current cooking program;

[0088] Get the weight of the food in the steam oven;

[0089] The volume of condensed water generated in the current cooking procedure is obtained according to the third steam curve, the cooking time and the weight of the food in the steam oven.

[0090] In the method of the embodiment of the present invention, the cooking time and the weight of the food in the oven can be comprehensively considered to finally obtain the volume of condensed water generated in the current cooking program. The third steam curve can be used to describe the steam rate / steam volume generated by different cooking times and different weights of food corresponding to the recipe.

[0091] In an embodiment of the present invention, the method further includes:

[0092] After the current cooking program ends, obtaining a second free capacity in the waste water box;

[0093] acquiring a third idle capacity according to the first idle capacity and the volume of condensed water generated in the current cooking procedure;

[0094] It is determined whether a difference between the second idle capacity and the third idle capacity is within a preset threshold value. If the difference is not within the preset threshold value, a corresponding steam curve is corrected, where the corresponding steam curve is one of the first steam curve, the second steam curve or the third steam curve.

[0095] In the embodiment of the present invention, the first steam curve, the second steam curve and the third steam curve may be preset at the factory, but for users with different cooking habits, different cooking tastes, and different cooking conditions, the preset steam curves may have certain errors, so they may be modified according to actual usage conditions, thereby providing users with a better usage experience.

[0096] In the embodiment of the present invention, after generating the condensate clearing alarm, the method further includes:

[0097] Real-time acquisition of the fourth free capacity in the wastewater box;

[0098] Determining whether the condensed water volume is less than or equal to the fourth idle capacity;

[0099] If the condensed water volume is less than or equal to the fourth idle capacity, the current cooking program is executed according to the start command.

[0100] In the embodiment of the present invention, after the condensate clearing alarm is generated, the user is waited to clear the waste water box. The fourth free capacity in the waste water box is obtained in real time to determine whether the user has cleared the waste water box. After the user has cleared the waste water box, it is determined that the condensate volume is less than or equal to the fourth free capacity, and the steam oven is started to execute the cooking program, thereby avoiding overflow of the waste water box when the cooking program is not completed.

[0101] If the waste water box is emptied, that is, the fourth free capacity is equal to the maximum capacity of the waste water box, and the volume of condensed water that may be generated is still greater than the fourth free capacity, then an alarm will still be issued, but the cooking program will still be executed after the customer confirms the alarm. In this application scenario, the user will be prompted to empty the waste water box during a time period that has less impact on the cooking program to avoid overflow of the waste water box.
