Description

Technical Field

[0001] This invention relates to the field of steam oven technology, and in particular to a water inlet control method and device for a dual-cavity steam oven, as well as a computer-storable medium. Background Technology

[0002] Steam ovens are a new type of cooking tool that has become popular in the market in recent years. They have functions such as pure steaming, pure baking, steam baking, fermentation, sterilization, and heat preservation. Among them, the dual-cavity series of steam ovens have two independent working chambers that can work simultaneously, such as steaming from both sides at the same time, steaming from the left and baking from the right, or steaming from the left and steaming from the right and baking from the right.

[0003] However, most dual-cavity steam ovens currently on the market use a separate water pump to supply the steam chamber. If both cavities need to be supplied with steam, two water pumps are required to supply water to the water trays of the two cavities. This can lead to two water pumps simultaneously receiving instructions and competing for water from the water tanks, which may result in insufficient water pumping from the two cavities, leading to insufficient steam or dry burning.

[0004] Patent 202111408025.1 discloses a steam oven and integrated stove that does not employ the aforementioned structure. It utilizes a single steam generator to simultaneously supply steam to both cooking cavities, allowing the dual cavities of the steam oven to steam and bake simultaneously, or steam twice at the same time. This structure is relatively simple and eliminates the need for two water lines, which would otherwise make the device bulky. However, this patent still requires steam distribution, and users typically limit cooking time. How to distribute steam within the cooking time to meet user settings needs to be addressed. Furthermore, the steam generator is less convenient to disassemble and clean than a water tray. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a water inlet control method and device for a dual-cavity steam oven, and a computer-storable medium, which is capable of...

[0006] To address the aforementioned technical problems, the first aspect of this invention discloses a water inlet control method for a dual-cavity steam oven. The dual-cavity steam oven includes a water tank, a main pipe, a water pump for drawing water from the water tank and supplying it to the main pipe, a first steam-baking cavity, a second steam-baking cavity, and a first input device for the user to input the steaming / baking time, wherein:

[0007] The dual-cavity steam oven further includes a first water tray for generating steam to the first steam oven cavity, a first branch pipe that serves as a branch of the main pipe and supplies water to the first water tray, a second water tray for generating steam to the second steam oven cavity, a second branch pipe that serves as another branch of the main pipe and supplies water to the second water tray, a first solenoid valve for controlling the opening and closing and flow rate of the first branch pipe, a second solenoid valve for controlling the opening and closing and flow rate of the second branch pipe, and a second input device for users to input food information.

[0008] The water inlet control method includes:

[0009] The system can acquire, in real time, the first start-up information sent by the user for the first steam oven cavity and the second start-up information for the second steam oven cavity;

[0010] When the first start information and the second start information are obtained simultaneously, the first solenoid valve and the second solenoid valve are opened, and the water pump is controlled to draw a first amount of liquid water from the water tank and send it to the main pipeline. After the drawing is completed, the water pump, the first solenoid valve and the second solenoid valve are closed. The first amount of water is not greater than twice the amount of liquid water corresponding to the maximum steam demand of the steam oven with the smaller maximum steam demand in the first steam oven and the second steam oven.

[0011] The system obtains a first preset water intake volume for each water intake of the first water pan (excluding the initial water intake) and a second preset water intake volume for each water intake of the second water pan (excluding the initial water intake). The system controls the water pump to start pumping water when the first or second water pan is almost dry. The system controls the first solenoid valve to open when the first water pan is almost dry and close after receiving the first preset water intake volume into the first water pan. The system controls the second solenoid valve to open when the second water pan is almost dry and close after receiving the second preset water intake volume into the second water pan.

[0012] As an optional implementation, in the first aspect of the present invention, the maximum steam demand corresponding to the first steam oven cavity is the volume of the first steam oven cavity, and the liquid water volume corresponding to the maximum steam demand of the first steam oven cavity is the volume or mass of water at room temperature corresponding to the steam at the preset temperature that fills the first steam oven cavity.

[0013] As another optional implementation, in the first aspect of the present invention, the method for determining whether the first water pan is about to boil dry is as follows:

[0014] The unit steam consumption of the dual-cavity steam oven is obtained. Based on the unit steam consumption, the working time of the dual-cavity steam oven, and the water intake of the dual-cavity steam oven, it is determined whether the remaining water percentage of the first water pan is less than or equal to a preset value. When it is determined to be yes, it is determined that the first water pan is about to boil dry.

[0015] As another optional implementation, in the first aspect of the invention, the remaining water percentage E of the first water tray is calculated using the following formula:

[0016] E = (Q s -S*t s ) / Q s ;

[0017] Among them, Q s The previous water intake volume is t, where S is the unit steam consumption of the dual-cavity steam oven. s The operating time of the dual-cavity steam oven is from the last time water was introduced until the current moment.

[0018] As another optional implementation, in the first aspect of the invention, the unit steam consumption of the dual-cavity steam oven is obtained by the following method:

[0019] A humidity probe is installed inside the first steam oven cavity to detect the humidity inside the cavity. Water Q0 is initially added to the first water tray and heated. When the humidity probe first detects a humidity level of 95% after the initial water addition, the current time is recorded and the remaining water volume F in the first water tray is measured. The unit steam consumption S1 of the first steam oven cavity is calculated using the following formula:

[0020] S1 = (Q0 - F) / t0;

[0021] Where Q0 is the initial water intake, F is the remaining water in the first water pan after the initial water intake to reach a humidity ratio of 95% for the first time, and t0 is the time from the initial water intake to the first time the humidity ratio reaches 95%.

[0022] S1 is defined as the unit steam consumption S of the dual-cavity steam oven.

[0023] As another optional implementation, in the first aspect of the invention, after acquiring in real time the first start information and the second start information sent by the user for the first steam-oven cavity, the method further includes:

[0024] When only the first start information is obtained, the first solenoid valve is controlled to open, and the water pump is controlled to draw a second amount of liquid water from the water tank and send it to the main pipeline; the second amount of liquid water is the amount of liquid water corresponding to the maximum steam demand of the first steam oven cavity;

[0025] Obtain the first preset water intake volume for each water intake of the first water pan, excluding the initial water intake;

[0026] The water pump is controlled to start pumping water when the first water pan is almost dry, and the first solenoid valve is controlled to open when the first water pan is almost dry and close after receiving the first preset water intake volume in the first water pan.

[0027] As another optional implementation, in the first aspect of the invention, after acquiring in real time the first start information and the second start information sent by the user for the first steam-oven cavity, the method further includes:

[0028] When the first startup information is obtained before the second startup information is obtained, and the time difference between the first and second startup information is greater than a preset time difference, the first solenoid valve is controlled to open at the first startup time and the second solenoid valve is controlled to open at the second startup time.

[0029] The system controls the water pump to draw a third volume of liquid water from the water tank and deliver it to the main pipeline, and then shuts off the water pump after the drawing is completed; the system controls the first solenoid valve to close at a third time, and the system controls the second solenoid valve to close at a fourth time; the third volume of water is the sum of the maximum steam demand of the first steam oven cavity and the maximum steam demand of the second steam oven cavity; the third time is the moment when the amount of water entering the first water pan from the first time just reaches the maximum steam demand of the first steam oven cavity; and the fourth time is the moment when the amount of water entering the second water pan from the second time just reaches the maximum steam demand of the second steam oven cavity.

[0030] Obtain the first preset water intake volume for each water intake of the first water pan (excluding the first water intake) and the second preset water intake volume for each water intake of the second water pan (excluding the first water intake);

[0031] The water pump is controlled to start pumping water when the first water pan or the second water pan is almost dry. The first solenoid valve is controlled to open when the first water pan is almost dry and to close after receiving the first preset water intake amount in the first water pan. The second solenoid valve is controlled to open when the second water pan is almost dry and to close after receiving the second preset water intake amount in the second water pan.

[0032] As another optional implementation, in the first aspect of the present invention, the volume of the first water tray is greater than the maximum steam demand corresponding to the first steam oven cavity, and the volume of the second water tray is greater than the maximum steam demand corresponding to the second steam oven cavity.

[0033] A second aspect of this invention discloses a water inlet control device for a dual-cavity steam oven, comprising:

[0034] Memory containing executable program code;

[0035] A processor coupled to the memory;

[0036] The processor calls the executable program code stored in the memory to execute the steps in the water inlet control method of a dual-cavity steam oven disclosed in the first aspect of the present invention.

[0037] The third aspect of the present invention discloses a computer storage medium storing computer instructions, which, when invoked, are used to execute the steps of the water inlet control method for a dual-cavity steam oven disclosed in the first aspect of the present invention.

[0038] Compared with the prior art, the embodiments of the present invention have the following beneficial effects:

[0039] Compared to existing technologies, this invention features a single-pump, dual-cavity steam oven that generates steam directly in the water pan, making it easy to disassemble and clean. In practical use, both cavities in the dual-cavity steam oven can be used. Since cooking time is usually limited, a sequential water intake is not feasible; instead, water is added simultaneously. The initial water intake in this invention prevents both cavities from drying out and avoids overfilling, ensuring rapid steam generation and optimal cooking results. Furthermore, subsequent water intakes are only added when either cavity is nearly dry, preventing dry burning and excessive water intake, thus achieving continuous and precise water intake control during operation. Each cavity receives its own water intake, and the timing for water intake and cessation is determined, solving the problem of water distribution during simultaneous intake.

[0044] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] Example 1

[0046] This invention discloses a water inlet control method for a dual-cavity steam oven, see [link to relevant documentation]. Figure 1 The dual-cavity steam oven includes a water tank 1, a main pipe 2, a water pump 3 for drawing water from the water tank and sending it to the main pipe, a first steaming and baking cavity 4, a second steaming and baking cavity 5, and a first input device 6 for the user to input the steaming and baking time, wherein:

[0047] The dual-cavity steam oven further includes a first water tray 71 for generating steam to the first steam oven cavity, a first branch pipe 81 that serves as a branch of the main pipe and supplies water to the first water tray, a second water tray 72 for generating steam to the second steam oven cavity, a second branch pipe 82 that serves as another branch of the main pipe and supplies water to the second water tray, a first solenoid valve 91 for controlling the opening and closing and flow rate of the first branch pipe, a second solenoid valve 92 for controlling the opening and closing and flow rate of the second branch pipe, and a second input device 10 for users to input food information.

[0048] See Figure 2 The water inlet control method includes:

[0049] 101. Real-time acquisition of the first start-up information sent by the user for the first steam oven cavity and the second start-up information for the second steam oven cavity.

[0050] In this embodiment of the invention, the first startup information includes the user-set steaming and baking time of the first steaming and baking cavity output by the first input device and the food information of the food to be processed placed in the first steaming and baking cavity output by the second input device. The second startup information includes the user-set steaming and baking time of the second steaming and baking cavity output by the first input device and the food information of the food to be processed placed in the second steaming and baking cavity output by the second input device.

[0051] Before steaming or baking, the user submits information about the ingredients via a second input device. This second input device can be a button, key, knob, or touchscreen located on the exterior of the steam oven. Once the user selects a setting, the corresponding signal is emitted. The first input device is typically a knob, which is used to select the steaming or baking time.

[0052] 102. When the first start information and the second start information are obtained simultaneously, the first solenoid valve and the second solenoid valve are controlled to open, and the water pump is controlled to draw a first amount of liquid water from the water tank and send it to the main pipeline. After the drawing is completed, the water pump, the first solenoid valve and the second solenoid valve are closed.

[0053] It should be noted that the maximum steam demand corresponding to the first steam oven cavity is the volume of the first steam oven cavity, while the liquid water volume corresponding to the maximum steam demand of the first steam oven cavity is the volume or mass of water at room temperature corresponding to the preset temperature steam filling the first steam oven cavity. Generally, steaming modes can be divided into nutrient steaming, high-temperature steaming, fermentation, and defrosting. In this embodiment, different steaming modes correspond to different preset steam temperatures; for example, the steam temperature required for nutrient steaming and high-temperature steaming is 100 degrees Celsius, while the steam temperature required for fermentation and defrosting is 40 degrees Celsius.

[0054] For example, assuming the volume of the first steam oven cavity is 50L, and its maximum steam requirement is also 50L, then 50L of steam at 100 degrees Celsius requires the evaporation of 32.1g of water at room temperature (assumed to be 25 degrees Celsius). Therefore, the maximum steam requirement of the first steam oven cavity corresponds to 32.1g or 32.1mL of liquid water. The calculation process for 50L of steam at 100 degrees Celsius requiring the evaporation of 32.1g of water at 25 degrees Celsius is as follows:

[0055] The absolute temperature of 25 degrees Celsius is 298 K, and the absolute temperature of 100 degrees Celsius is 373 K. Under standard conditions, 1 mole of gaseous water is approximately 0.0224 cubic meters (the molar volume of an ideal gas), and the mass of 1 mole of water is 18 g. According to Gay-Lussac's law, (V1 / T1) = (V2 / T2), where V1 is the volume of 1 mole of liquid water at 25 degrees Celsius, T1 is 298 K (20 degrees), and V2 is the volume of 1 mole of gaseous water at 100 degrees Celsius, T2 is 373 K (100 degrees Celsius), so: V2 = (T2 / T1)V1 = 373 / 298 * 0.0224 = 0.028 (cubic meters / mole). Since 50 L = 0.05 cubic meters, then 0.05 / 0.028 * 18 g = 32.1 g.

[0056] In this embodiment of the invention, the first water inlet volume is no more than twice the liquid water volume corresponding to the maximum steam demand of the steam oven with the smaller maximum steam demand in the first and second steam ovens. The purpose is to provide less water than needed to fill the cavity with steam, thus avoiding steam saturation and the resulting condensation of excess steam into large water droplets that could reduce the cooking effect. Simultaneously, adding just the right amount of water to the water tray improves steam generation efficiency, thereby increasing the heating speed. Because water enters simultaneously, the water volume received by the water trays in both cavities is equal and half the first water inlet volume, ensuring that neither cavity receives more liquid water than its maximum steam demand. This avoids excessive steam demand, preventing both cavities from dry-burning and preventing excessive water addition, thus ensuring rapid steam generation and achieving better cooking results.

[0057] 103. Obtain the first preset water intake amount for each water intake of the first water pan (excluding the first water intake) and the second preset water intake amount for each water intake of the second water pan (excluding the first water intake). Control the water pump to start pumping water when the first water pan or the second water pan is about to dry out. Control the first solenoid valve to open when the first water pan is about to dry out and close it after the first water pan receives the first preset water intake amount. Control the second solenoid valve to open when the second water pan is about to dry out and close it after the second water pan receives the second preset water intake amount.

[0058] This invention relates to a steam oven with a single water pump and a dual-cavity structure. Steam is generated directly in the water pan, making it easy to disassemble and clean. In practical use, both cavities in the dual-cavity steam oven can be used. Since cooking time is usually limited, a sequential water intake is not feasible; instead, water is added simultaneously. The initial water intake in this invention prevents both cavities from drying out and avoids overfilling, ensuring rapid steam generation and optimal cooking results. Furthermore, subsequent water intakes are only added when either cavity is nearly dry, preventing dry burning and excessive water intake. This achieves continuous and precise water intake control during operation. Each cavity receives its own water intake, and the timing for water intake and cessation is determined, solving the problem of water distribution when water is added simultaneously.

[0059] In an optional embodiment, the method for determining whether the first water pan is about to boil dry is as follows:

[0060] The unit steam consumption of the dual-cavity steam oven is obtained. Based on the unit steam consumption, the working time of the dual-cavity steam oven, and the water intake of the dual-cavity steam oven, it is determined whether the remaining water percentage of the first water pan is less than or equal to a preset value. When it is determined to be yes, it is determined that the first water pan is about to boil dry.

[0061] Optionally, the preset value can be 5-20%.

[0062] Optionally, the remaining water percentage E in the first water tray can be calculated using the following formula:

[0063] E = (Q s -S*t s ) / Q s ;

[0064] Among them, Q s The previous water intake volume is t, where S is the unit steam consumption of the dual-cavity steam oven. s The operating time of the dual-cavity steam oven is from the last time water was introduced until the current moment.

[0065] Optionally, the unit steam consumption of the dual-cavity steam oven can be obtained by the following method:

[0066] A humidity probe is installed inside the first steam oven cavity to detect the humidity inside the cavity. Water Q0 is initially added to the first water tray and heated. When the humidity probe first detects a humidity level of 95% after the initial water addition, the current time is recorded and the remaining water volume F in the first water tray is measured. The unit steam consumption S1 of the first steam oven cavity is calculated using the following formula:

[0067] S1 = (Q0 - F) / t0;

[0068] Where Q0 is the initial water intake, F is the remaining water in the first water pan after the initial water intake to reach a humidity ratio of 95% for the first time, and t0 is the time from the initial water intake to the first time the humidity ratio reaches 95%.

[0069] S1 is defined as the unit steam consumption S of the dual-cavity steam oven. The initial water intake only needs to be sufficient to achieve a cavity humidity of 95% without causing dry burning.

[0070] Alternatively, the unit steam consumption S2 of the second steam oven can also be calculated in the same way as above, and the average value of S1 and S2 can be taken as the unit steam consumption S of the dual-cavity steam oven.

[0071] In yet another optional embodiment, after acquiring in real time the first start-up information and the second start-up information sent by the user for the first steam-oven cavity, the method further includes:

[0072] When only the first start information is obtained, the first solenoid valve is controlled to open, and the water pump is controlled to draw a second amount of liquid water from the water tank and send it to the main pipeline; the second amount of liquid water is the amount of liquid water corresponding to the maximum steam demand of the first steam oven cavity;

[0073] Obtain the first preset water intake volume for each water intake of the first water pan, excluding the initial water intake;

[0074] The water pump is controlled to start pumping water when the first water pan is almost dry, and the first solenoid valve is controlled to open when the first water pan is almost dry and close after receiving the first preset water intake volume in the first water pan.

[0075] This embodiment describes the water inlet control method when only one cavity is filled with water.

[0076] In yet another optional embodiment, after acquiring in real time the first start-up information and the second start-up information sent by the user for the first steam-oven cavity, the method further includes:

[0077] When the first startup information is obtained before the second startup information is obtained, and the time difference between the first and second startup information is greater than a preset time difference, the first solenoid valve is controlled to open at the first startup time and the second solenoid valve is controlled to open at the second startup time.

[0078] The system controls the water pump to draw a third volume of liquid water from the water tank and deliver it to the main pipeline, and then shuts off the water pump after the drawing is completed; the system controls the first solenoid valve to close at a third time, and the system controls the second solenoid valve to close at a fourth time; the third volume of water is the sum of the maximum steam demand of the first steam oven cavity and the maximum steam demand of the second steam oven cavity; the third time is the moment when the amount of water entering the first water pan from the first time just reaches the maximum steam demand of the first steam oven cavity; and the fourth time is the moment when the amount of water entering the second water pan from the second time just reaches the maximum steam demand of the second steam oven cavity.

[0079] Obtain the first preset water intake volume for each water intake of the first water pan (excluding the first water intake) and the second preset water intake volume for each water intake of the second water pan (excluding the first water intake);

[0080] The water pump is controlled to start pumping water when the first water pan or the second water pan is almost dry. The first solenoid valve is controlled to open when the first water pan is almost dry and to close after receiving the first preset water intake amount in the first water pan. The second solenoid valve is controlled to open when the second water pan is almost dry and to close after receiving the second preset water intake amount in the second water pan.

[0081] This embodiment describes a scenario where the two chambers do not fill with water simultaneously, but rather in the order of startup. The preset time difference can be 1 second, or can be set according to the actual situation.

[0082] In another optional embodiment, the volume of the first water tray is greater than the maximum steam demand corresponding to the first steam oven cavity, and the volume of the second water tray is greater than the maximum steam demand corresponding to the second steam oven cavity.
