Description

Technical Field

[0001] The present invention relates to the field of control technology, and in particular to a water inlet control method, a control device, a readable storage medium and a cooking device. Background Art

[0002] In the related technical solution, taking a steam oven as an example, in order to realize the "steaming" function, a water storage box needs to be provided in the cooking device.

[0003] Among them, with the use of the "steaming" function, the user is required to store water in the water storage box. Frequent water storage makes the user experience of the cooking equipment relatively poor.

[0004] At the same time, if there is too much water in the water storage box, scale will form and accumulate in the water storage box, affecting the user experience of the cooking equipment. Summary of the invention

[0005] The present invention aims to at least solve the technical problem in the prior art or related art that frequent water storage results in a poor user experience of the cooking device, and at the same time, if too much water is stored in the water storage box, scale will form and accumulate in the water storage box, affecting the user experience of the cooking device.

[0006] To this end, a first aspect of the present invention is to provide a water inlet control method.

[0007] A second aspect of the present invention provides a water inlet control device.

[0008] A third aspect of the present invention is to provide another water inlet control device.

[0009] A fourth aspect of the present invention provides a readable storage medium.

[0010] A fifth aspect of the present invention provides a cooking device.

[0011] A sixth aspect of the present invention provides another cooking device.

[0012] In view of this, according to a first aspect of the present invention, there is provided a water inlet control method for a cooking device, the cooking device comprising a water storage box, a steam generator, a liquid injection assembly and a first liquid level gauge arranged in the water storage box, the first liquid level gauge being located at the bottom of the water storage box, the water inlet control method comprising: when a first operating condition is detected, controlling the liquid injection assembly to inject a first volume of liquid into the water storage box; when the first operating condition is detected again, determining a second volume according to a remaining cooking time, a first cooking time and a first volume, the first cooking time being the time required for the steam generator to consume the first volume of liquid; controlling the liquid injection assembly to inject the second volume of liquid into the water storage box; wherein the first operating condition is that the first liquid level gauge is triggered and the operating temperature of the steam generator is greater than or equal to a first temperature threshold.

[0013] The present invention proposes a water inlet control method. By running the above water inlet control method, the liquid injection component can be used to realize automatic liquid injection of the water storage box, and the liquid injection amount of the liquid injection component into the water storage box each time can be dynamically adjusted according to the remaining cooking time of the cooking equipment.

[0014] During this process, since the filling component realizes automatic filling of the water storage box, the user does not need to manually fill the water storage box. Therefore, the user is prevented from frequently filling the water storage box, and the frequent interaction between the user and the cooking device is reduced, thereby improving the user experience of the cooking device.

[0015] Since the amount of liquid injected into the water box by the injection component each time can be dynamically adjusted according to the remaining cooking time of the cooking device, a reasonable amount of liquid can be injected into the water box, avoiding residual liquid in the water box after cooking. When there is no or almost no residual liquid in the water box, the probability of scale forming and accumulating in the water box can be reduced, thereby allowing the water box to remain clean, thereby improving the user experience.

[0016] In the above technical solution, the first working condition can be used to characterize the current water storage state of the water storage box. Specifically, the first liquid level gauge is set at the bottom of the water storage box. If the first liquid level gauge is triggered, it is considered that the liquid in the current water storage box has been exhausted. At the same time, when the operating temperature of the steam generator is greater than or equal to the first temperature threshold, it is considered that the liquid in the pipeline between the water storage box and the steam generator is also exhausted, and the steam generator has a dry burning situation.

[0017] When the first operating condition is detected for the first time, the liquid injection component will inject a first volume of liquid into the water storage box. When the first operating condition is detected again, it is considered that the first volume of liquid is consumed by the steam generator, and the first cooking time is the time required for the first volume of liquid to be consumed by the steam generator. In the process of determining the second volume, the first cooking time and the remaining cooking time are referred to, so that the second volume can be determined according to the actual operation of the steam generator. In this process, the second volume can accurately represent the amount of liquid required to complete cooking, and accurately inject liquid into the water storage box, thereby reducing the probability of scale forming and accumulating in the water storage box, and then the water storage box can be kept clean, thereby improving the user experience.

[0018] The height of the liquid medium in the container is called the liquid level, and the instrument for measuring the liquid level is called a liquid level meter. The liquid level meter is a type of level instrument.

[0019] In the technical solution of the present invention, the first liquid level gauge is a liquid level gauge arranged at the bottom of the water storage box.

[0020] In some technical solutions, the first liquid level meter can be any one of a tuning fork vibration type, a magnetic levitation type, a pressure type, an ultrasonic type, a sonar wave, a magnetic flap, and a radar.

[0021] In some technical solutions, the remaining cooking time can be understood as the time the cooking device still needs to run when the cooking is in the process of cooking and before the cooking is finished.

[0022] In some technical solutions, the operating temperature of the steam generator can be detected by a temperature sensor arranged inside the steam generator.

[0023] In addition, the water inlet control method proposed by the present invention also has the following additional technical features.

[0024] In some technical schemes, optionally, the second volume is determined based on the remaining cooking time, the first cooking time and the first volume, specifically including: obtaining a first ratio of the remaining cooking time to the first cooking time; obtaining a third volume, the third volume being the product of the first ratio and the first volume; based on the third volume being greater than or equal to the first volume, taking the first volume as the second volume; based on the third volume being less than the first volume, taking the third volume as the second volume.

[0025] In this technical solution, since the first cooking time is the time required for the steam generator to consume the first volume of liquid, by calculating the ratio of the remaining cooking time to the first cooking time, that is, the first ratio, it is possible to estimate how many first volumes of liquid are required for the cooking device to run for the remaining cooking time. Combined with the first volume, the total amount of liquid required for the cooking device to run for the remaining cooking time can be estimated. If the total amount of liquid, that is, the third volume is greater than or equal to the first volume, only the first volume of liquid is injected into the water storage box for use by the steam generator.

[0026] In the case where the total amount of liquid is less than the first volume, a third volume of liquid is injected into the water storage box to meet the overall demand of the cooking device.

[0027] During this process, the single liquid filling amount of the water storage box does not exceed the first volume. Even if the cooking equipment stops cooking due to a malfunction or abnormality, a large amount of liquid can be avoided from remaining in the water storage box, thereby reducing the chance of scale forming and accumulating in the water storage box, so that the water storage box can be kept clean, thereby improving the user experience.

[0028] In some technical schemes, optionally, after taking the first volume as the second volume, the water inlet control method also includes: updating the first cooking time; after controlling the liquid injection component to inject the second volume of liquid into the water storage box, the water inlet control method also includes: updating the remaining cooking time; determining an updated first ratio based on the updated remaining cooking time and the updated first cooking time; determining an updated third volume based on the updated first ratio and the first volume; based on the updated third volume being greater than or equal to the first volume, controlling the liquid injection component to inject the first volume of liquid into the water storage box; based on the updated third volume being less than the first volume, controlling the liquid injection component to inject the updated third volume of liquid into the water storage box.

[0029] In this technical solution, after the first volume is used as the second volume, the first cooking time is updated so that when liquid is injected into the water storage box next time, the amount of liquid that needs to be injected into the water storage box can be re-evaluated based on the first cooking time and the updated remaining cooking time.

[0030] During this process, as cooking progresses, the first cooking time can be continuously updated, and then the liquid consumption of the steam generator can be continuously evaluated, thereby evaluating a new third volume, and injecting liquid into the water storage box according to the updated third volume. During this process, the amount of liquid injected into the water storage box is continuously corrected to ensure that the amount of liquid injected into the water storage box is just suitable for the amount consumed by the cooking equipment, thereby reducing the amount of liquid remaining in the water storage box after cooking is completed.

[0031] Obviously, in this process, the probability of scale forming and accumulating in the water storage box can be reduced, so that the water storage box can be kept clean, thereby improving the user experience.

[0032] In some technical solutions, optionally, when the first operating condition is detected again, before determining the second volume based on the remaining cooking time, the first cooking time and the first volume, the water inlet control method also includes: obtaining the total cooking time; and determining the remaining cooking time based on the total cooking time and the first cooking time.

[0033] In this technical solution, the remaining cooking time can be calculated based on the total cooking time and the first cooking time.

[0034] Among them, the total cooking time can be determined according to the menu pre-stored in the cooking device, and can also be set manually by the user. Its specific value will not be repeated here.

[0035] Exemplarily, the remaining cooking time is equal to the value obtained by subtracting the first cooking time from the total cooking time.

[0036] In some technical solutions, optionally, the first volume is the maximum water storage capacity of the water storage box.

[0037] In this technical solution, when the first volume is the maximum water storage capacity, the frequency of the liquid injection component injecting liquid into the water storage box can be reduced, thereby reducing the frequency of dry burning of the steam generator, thereby extending the service life of the steam generator.

[0038] In some technical solutions, optionally, the first volume is half of the maximum water storage capacity of the water storage box.

[0039] In some technical solutions, optionally, the first temperature threshold is greater than or equal to 170 degrees Celsius.

[0040] According to a second aspect of the present invention, the present invention provides a water inlet control device for a cooking device, the cooking device comprising a water storage box, a steam generator, a liquid injection assembly and a first liquid level gauge arranged in the water storage box, the first liquid level gauge is located at the bottom of the water storage box, the water inlet control device comprises: a control unit, for controlling the liquid injection assembly to inject a first volume of liquid into the water storage box when a first operating condition is detected; a determination unit, for determining a second volume according to a remaining cooking time, a first cooking time and a first volume when the first operating condition is detected again, the first cooking time being the time required for the steam generator to consume the first volume of liquid; the control unit is also used to control the liquid injection assembly to inject the second volume of liquid into the water storage box; wherein the first operating condition is that the first liquid level gauge is triggered and the operating temperature of the steam generator is greater than or equal to a first temperature threshold.

[0041] The present invention proposes a water inlet control device, which can realize automatic liquid filling of a water storage box by using a liquid filling component, and can also dynamically adjust the liquid filling amount of the liquid filling component into the water storage box each time according to the remaining cooking time of the cooking device.

[0042] During this process, since the filling component realizes automatic filling of the water storage box, the user does not need to manually fill the water storage box. Therefore, the user is prevented from frequently filling the water storage box, and the frequent interaction between the user and the cooking device is reduced, thereby improving the user experience of the cooking device.

[0043] Since the amount of liquid injected into the water box by the injection component each time can be dynamically adjusted according to the remaining cooking time of the cooking device, a reasonable amount of liquid can be injected into the water box, avoiding residual liquid in the water box after cooking. When there is no or almost no residual liquid in the water box, the probability of scale forming and accumulating in the water box can be reduced, thereby allowing the water box to remain clean, thereby improving the user experience.

[0044] In the above technical solution, the first working condition can be used to characterize the current water storage state of the water storage box. Specifically, the first liquid level gauge is set at the bottom of the water storage box. If the first liquid level gauge is triggered, it is considered that the liquid in the current water storage box has been exhausted. At the same time, when the operating temperature of the steam generator is greater than or equal to the first temperature threshold, it is considered that the liquid in the pipeline between the water storage box and the steam generator is also exhausted, and the steam generator has a dry burning situation.

[0045] When the first operating condition is detected for the first time, the liquid injection component will inject a first volume of liquid into the water storage box. When the first operating condition is detected again, it is considered that the first volume of liquid is consumed by the steam generator, and the first cooking time is the time required for the first volume of liquid to be consumed by the steam generator.

DETAILED DESCRIPTION

[0086] In order to more clearly understand the above aspects, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0087] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0088] In one embodiment of the present application, Figure 1 , Figure 2 and Figure 3 As shown, a water inlet control method is provided for a cooking device 200, the cooking device 200 includes a water storage box 202, a steam generator 204, a liquid injection component 206, and a first liquid level meter 208 disposed in the water storage box 202, the first liquid level meter 208 is located at the bottom of the water storage box 202, and the water inlet control method includes:

[0089] Step 102: when a first working condition is detected, controlling the liquid injection assembly to inject a first volume of liquid into the water storage box;

[0090] Step 104, when the first working condition is detected again, determining a second volume according to the remaining cooking time, the first cooking time and the first volume, wherein the first cooking time is the time required for the steam generator to consume the first volume of liquid;

[0091] Step 106, controlling the liquid injection assembly to inject a second volume of liquid into the water storage box.

[0092] The first operating condition is that the first liquid level gauge is triggered and the operating temperature of the steam generator is greater than or equal to the first temperature threshold.

[0093] The present invention proposes a water inlet control method. By running the above water inlet control method, the liquid injection component can be used to realize automatic liquid injection of the water storage box, and the liquid injection amount of the liquid injection component into the water storage box each time can be dynamically adjusted according to the remaining cooking time of the cooking equipment.

[0094] During this process, since the filling component realizes automatic filling of the water storage box, the user does not need to manually fill the water storage box. Therefore, the user is prevented from frequently filling the water storage box, and the frequent interaction between the user and the cooking device is reduced, thereby improving the user experience of the cooking device.

[0095] Since the amount of liquid injected into the water box by the injection component each time can be dynamically adjusted according to the remaining cooking time of the cooking device, a reasonable amount of liquid can be injected into the water box, avoiding residual liquid in the water box after cooking. When there is no or almost no residual liquid in the water box, the probability of scale forming and accumulating in the water box can be reduced, thereby allowing the water box to remain clean, thereby improving the user experience.

[0096] In the above technical solution, the first working condition can be used to characterize the current water storage state of the water storage box. Specifically, the first liquid level gauge is set at the bottom of the water storage box. If the first liquid level gauge is triggered, it is considered that the liquid in the current water storage box has been exhausted. At the same time, when the operating temperature of the steam generator is greater than or equal to the first temperature threshold, it is considered that the liquid in the pipeline between the water storage box and the steam generator is also exhausted, and the steam generator has a dry burning situation.

[0097] When the first operating condition is detected for the first time, the liquid injection component will inject a first volume of liquid into the water storage box. When the first operating condition is detected again, it is considered that the first volume of liquid is consumed by the steam generator, and the first cooking time is the time required for the first volume of liquid to be consumed by the steam generator. In the process of determining the second volume, the first cooking time and the remaining cooking time are referred to, so that the second volume can be determined according to the actual operation of the steam generator. In this process, the second volume can accurately represent the amount of liquid required to complete cooking, and accurately inject liquid into the water storage box, thereby reducing the probability of scale forming and accumulating in the water storage box, and then the water storage box can be kept clean, thereby improving the user experience.

[0098] The height of the liquid medium in the container is called the liquid level, and the instrument for measuring the liquid level is called a liquid level meter. The liquid level meter is a type of level instrument.

[0099] In the technical solution of the present invention, the first liquid level gauge is a liquid level gauge arranged at the bottom of the water storage box.

[0100] In some technical solutions, the first liquid level meter can be any one of a tuning fork vibration type, a magnetic levitation type, a pressure type, an ultrasonic type, a sonar wave, a magnetic flap, and a radar.

[0101] In some technical solutions, the remaining cooking time can be understood as the time the cooking device still needs to run when the cooking is in the process of cooking and before the cooking is finished.

[0102] In some technical solutions, the operating temperature of the steam generator can be detected by a temperature sensor arranged inside the steam generator.

[0103] In some technical schemes, optionally, the second volume is determined based on the remaining cooking time, the first cooking time and the first volume, specifically including: obtaining a first ratio of the remaining cooking time to the first cooking time; obtaining a third volume, the third volume being the product of the first ratio and the first volume; based on the third volume being greater than or equal to the first volume, taking the first volume as the second volume; based on the third volume being less than the first volume, taking the third volume as the second volume.

[0104] In this technical solution, since the first cooking time is the time required for the steam generator to consume the first volume of liquid, by calculating the ratio of the remaining cooking time to the first cooking time, that is, the first ratio, it is possible to estimate how many first volumes of liquid are required for the cooking device to run for the remaining cooking time. Combined with the first volume, the total amount of liquid required for the cooking device to run for the remaining cooking time can be estimated. If the total amount of liquid, that is, the third volume is greater than or equal to the first volume, only the first volume of liquid is injected into the water storage box for use by the steam generator.

[0105] In the case where the total amount of liquid is less than the first volume, a third volume of liquid is injected into the water storage box to meet the overall demand of the cooking device.

[0106] During this process, the single liquid filling amount of the water storage box does not exceed the first volume. Even if the cooking equipment stops cooking due to a malfunction or abnormality, a large amount of liquid can be avoided from remaining in the water storage box, thereby reducing the chance of scale forming and accumulating in the water storage box, so that the water storage box can be kept clean, thereby improving the user experience.

[0107] In some technical schemes, optionally, after taking the first volume as the second volume, the water inlet control method also includes: updating the first cooking time; after controlling the liquid injection component to inject the second volume of liquid into the water storage box, the water inlet control method also includes: updating the remaining cooking time; determining an updated first ratio based on the updated remaining cooking time and the updated first cooking time; determining an updated third volume based on the updated first ratio and the first volume; based on the updated third volume being greater than or equal to the first volume, controlling the liquid injection component to inject the first volume of liquid into the water storage box; based on the updated third volume being less than the first volume, controlling the liquid injection component to inject the updated third volume of liquid into the water storage box.

[0108] In this technical solution, after the first volume is used as the second volume, the first cooking time is updated so that when liquid is injected into the water storage box next time, the amount of liquid that needs to be injected into the water storage box can be re-evaluated based on the first cooking time and the updated remaining cooking time.

[0109] During this process, as cooking progresses, the first cooking time can be continuously updated, and then the liquid consumption of the steam generator can be continuously evaluated, thereby evaluating a new third volume, and injecting liquid into the water storage box according to the updated third volume. During this process, the amount of liquid injected into the water storage box is continuously corrected to ensure that the amount of liquid injected into the water storage box is just suitable for the amount consumed by the cooking equipment, thereby reducing the amount of liquid remaining in the water storage box after cooking is completed.

[0110] Obviously, in this process, the probability of scale forming and accumulating in the water storage box can be reduced, so that the water storage box can be kept clean, thereby improving the user experience.

[0111] In some technical solutions, optionally, when the first operating condition is detected again, before determining the second volume based on the remaining cooking time, the first cooking time and the first volume, the water inlet control method also includes: obtaining the total cooking time; and determining the remaining cooking time based on the total cooking time and the first cooking time.

[0112] In this technical solution, the remaining cooking time can be calculated based on the total cooking time and the first cooking time.

[0113] Among them, the total cooking time can be determined according to the menu pre-stored in the cooking device, and can also be set manually by the user. Its specific value will not be repeated here.

[0114] Exemplarily, the remaining cooking time is equal to the value obtained by subtracting the first cooking time from the total cooking time.

[0115] In some technical solutions, optionally, the first volume is the maximum water storage capacity of the water storage box.

[0116] In this technical solution, when the first volume is the maximum water storage capacity, the frequency of the liquid injection component injecting liquid into the water storage box can be reduced, thereby reducing the frequency of dry burning of the steam generator, thereby extending the service life of the steam generator.

[0117] In some technical solutions, optionally, the first volume is half of the maximum water storage capacity of the water storage box.

[0118] In some technical solutions, optionally, the first temperature threshold is greater than or equal to 170 degrees Celsius.

[0119] In one embodiment, after cooking starts, the cooking time is set to 30 minutes. At this time, there is no water in the water box, the lower liquid level meter is triggered, the evaporator is dry-burned, and the temperature exceeds 170 degrees Celsius. At this time, the electromagnetic water inlet valve is opened, and the amount of water added for cooking is set to 100 ml. The real-time flow calculated by the flow meter is integrated to obtain the water inflow. When it is dried again, 10 minutes have passed, and the remaining cooking time is 20 minutes. It is estimated that (20 / 10)×100 ml of water is needed, so a maximum of 100 ml of water is compensated. Then 100 ml of water is added again, and the water is consumed after another 15 minutes. At this time, the remaining cooking time is 5 minutes, and the water to be compensated is calculated to be (5 / 15)×100 ml=33 ml. A signal to compensate 33 ml of water is sent to the target flow until cooking is finished.

[0120] Among them, 30min is the total cooking time, 10min is the first cooking time, 15min is the updated first cooking time, and 100ml is the first volume.

[0121] In one embodiment, if Figure 4 As shown, the present invention provides a water inlet control device 400, which is used for a cooking device. The cooking device includes a water storage box, a steam generator, a liquid injection component and a first liquid level gauge arranged in the water storage box, the first liquid level gauge is located at the bottom of the water storage box, and the water inlet control device includes: a control unit 402, which is used to control the liquid injection component to inject a first volume of liquid into the water storage box when a first operating condition is detected; a determination unit 404, which is used to determine a second volume according to a remaining cooking time, a first cooking time and a first volume when the first operating condition is detected again, the first cooking time being the time required for the steam generator to consume the first volume of liquid; the control unit 402 is also used to control the liquid injection component to inject the second volume of liquid into the water storage box; wherein the first operating condition is that the first liquid level gauge is triggered and the operating temperature of the steam generator is greater than or equal to the first temperature threshold.

[0122] The present invention proposes a water inlet control device 400, which can realize automatic liquid filling of a water storage box by using a liquid filling component, and can also dynamically adjust the liquid filling amount of the liquid filling component into the water storage box each time according to the remaining cooking time of the cooking device.

[0123] During this process, since the filling component realizes automatic filling of the water storage box, the user does not need to manually fill the water storage box. Therefore, the user is prevented from frequently filling the water storage box, and the frequent interaction between the user and the cooking device is reduced, thereby improving the user experience of the cooking device.

[0124] Since the amount of liquid injected into the water box by the injection component each time can be dynamically adjusted according to the remaining cooking time of the cooking device, a reasonable amount of liquid can be injected into the water box, avoiding residual liquid in the water box after cooking. When there is no or almost no residual liquid in the water box, the probability of scale forming and accumulating in the water box can be reduced, thereby allowing the water box to remain clean, thereby improving the user experience.

[0125] In the above technical solution, the first working condition can be used to characterize the current water storage state of the water storage box. Specifically, the first liquid level gauge is set at the bottom of the water storage box. If the first liquid level gauge is triggered, it is considered that the liquid in the current water storage box has been exhausted. At the same time, when the operating temperature of the steam generator is greater than or equal to the first temperature threshold, it is considered that the liquid in the pipeline between the water storage box and the steam generator is also exhausted, and the steam generator has a dry burning situation.

[0126] When the first operating condition is detected for the first time, the liquid injection component will inject a first volume of liquid into the water storage box. When the first operating condition is detected again, it is considered that the first volume of liquid is consumed by the steam generator, and the first cooking time is the time required for the first volume of liquid to be consumed by the steam generator. In the process of determining the second volume, the first cooking time and the remaining cooking time are referred to, so that the second volume can be determined according to the actual operation of the steam generator. In this process, the second volume can accurately represent the amount of liquid required to complete cooking, and accurately inject liquid into the water storage box, thereby reducing the probability of scale forming and accumulating in the water storage box, and then the water storage box can be kept clean, thereby improving the user experience.

[0127] The height of the liquid medium in the container is called the liquid level, and the instrument for measuring the liquid level is called a liquid level meter. The liquid level meter is a type of level instrument.

[0128] In the technical solution of the present invention, the first liquid level gauge is a liquid level gauge arranged at the bottom of the water storage box.

[0129] In some technical solutions, the first liquid level meter can be any one of a tuning fork vibration type, a magnetic levitation type, a pressure type, an ultrasonic type, a sonar wave, a magnetic flap, and a radar.

[0130] In some technical solutions, the remaining cooking time can be understood as the time the cooking device still needs to run when the cooking is in the process of cooking and before the cooking is finished.

[0131] In some technical solutions, the operating temperature of the steam generator can be detected by a temperature sensor arranged inside the steam generator.

[0132] In addition, the water inlet control device proposed by the present invention also has the following additional technical features.

[0133] In some technical solutions, optionally, the determination unit 404 is specifically used to: obtain a first ratio of the remaining cooking time to the first cooking time; obtain a third volume, where the third volume is the product of the first ratio and the first volume; based on the third volume being greater than or equal to the first volume, taking the first volume as the second volume; based on the third volume being less than the first volume, taking the third volume as the second volume.

[0134] In this technical solution, since the first cooking time is the time required for the steam generator to consume the first volume of liquid, by calculating the ratio of the remaining cooking time to the first cooking time, that is, the first ratio, it is possible to estimate how many first volumes of liquid are required for the cooking device to run for the remaining cooking time. Combined with the first volume, the total amount of liquid required for the cooking device to run for the remaining cooking time can be estimated. If the total amount of liquid, that is, the third volume is greater than or equal to the first volume, only the first volume of liquid is injected into the water storage box for use by the steam generator.

[0135] In the case where the total amount of liquid is less than the first volume, a third volume of liquid is injected into the water storage box to meet the overall demand of the cooking device.

[0136] During this process, the single liquid filling amount of the water storage box does not exceed the first volume. Even if the cooking equipment stops cooking due to a malfunction or abnormality, a large amount of liquid can be avoided from remaining in the water storage box, thereby reducing the chance of scale forming and accumulating in the water storage box, so that the water storage box can be kept clean, thereby improving the user experience.

[0137] In some technical schemes, optionally, after taking the first volume as the second volume, the control unit 402 is also used to: update the first cooking time; after controlling the liquid injection component to inject the second volume of liquid into the water storage box, the control unit 402 is also used to: update the remaining cooking time; determine an updated first ratio based on the updated remaining cooking time and the updated first cooking time; determine an updated third volume based on the updated first ratio and the first volume; based on the updated third volume being greater than or equal to the first volume, control the liquid injection component to inject the first volume of liquid into the water storage box; based on the updated third volume being less than the first volume, control the liquid injection component to inject the updated third volume of liquid into the water storage box.

[0138] In this technical solution, after the first volume is used as the second volume, the first cooking time is updated so that when liquid is injected into the water storage box next time, the amount of liquid that needs to be injected into the water storage box can be re-evaluated based on the first cooking time and the updated remaining cooking time.

[0139] During this process, as cooking progresses, the first cooking time can be continuously updated, and then the liquid consumption of the steam generator can be continuously evaluated, thereby evaluating a new third volume, and injecting liquid into the water storage box according to the updated third volume. During this process, the amount of liquid injected into the water storage box is continuously corrected to ensure that the amount of liquid injected into the water storage box is just suitable for the amount consumed by the cooking equipment, thereby reducing the amount of liquid remaining in the water storage box after cooking is completed.

[0140] Obviously, in this process, the probability of scale forming and accumulating in the water storage box can be reduced, so that the water storage box can be kept clean, thereby improving the user experience.

[0141] In some technical solutions, optionally, when the first operating condition is detected again, before determining the second volume based on the remaining cooking time, the first cooking time and the first volume, the control unit 402 is also used to: obtain the total cooking time; and determine the remaining cooking time based on the total cooking time and the first cooking time.

[0142] In this technical solution, the remaining cooking time can be calculated based on the total cooking time and the first cooking time.

[0143] Among them, the total cooking time can be determined according to the menu pre-stored in the cooking device, and can also be set manually by the user. Its specific value will not be repeated here.

[0144] Exemplarily, the remaining cooking time is equal to the value obtained by subtracting the first cooking time from the total cooking time.

[0145] In some technical solutions, optionally, the first volume is the maximum water storage capacity of the water storage box.

[0146] In this technical solution, when the first volume is the maximum water storage capacity, the frequency of the liquid injection component injecting liquid into the water storage box can be reduced, thereby reducing the frequency of dry burning of the steam generator, thereby extending the service life of the steam generator.

[0147] In some technical solutions, optionally, the first volume is half of the maximum water storage capacity of the water storage box.

[0148] In some technical solutions, optionally, the first temperature threshold is greater than or equal to 170 degrees Celsius.

[0154] In this technical solution, a main water inlet valve 2062 is provided so that the main water inlet valve 2062 can be used to connect with other devices, wherein the other devices can be understood as devices that supply liquid to the cooking device 200.

The electromagnetic water inlet valve 2068 can extend its service life under the pressure-stable water flow.

[0156] In addition, while the constant pressure valve 2064 eliminates pressure fluctuations in the water circuit, it also provides a basis for the flow meter 2066 to measure the injection volume, allowing the flow meter 2066 to work under a stable pressure, thereby achieving accurate measurement of the injection volume, allowing the cooking equipment 200 to achieve precise injection.
