DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions 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 only part of the embodiments of the present invention, not all of the embodiments. The components of the embodiments of the present invention generally described and shown in the drawings herein can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present invention.

[0021] Considering that the existing oil spraying method generally adopts a fixed method for spraying oil, it is not flexible enough and cannot be adjusted according to the actual situation of the food. Based on this, the embodiment of the present invention provides a grilling tray assembly and an automatic oil discharge control method, which are described below through embodiments.

[0022] An embodiment of the present invention provides a baking tray assembly, such as Figure 1 As shown, it includes: a baking tray base plate and a baking tray side plate surrounding the baking tray base plate, wherein the two opposite sides of the baking tray side plate are respectively rotatably connected to the baking tray base plate via a rotating member, and a mechanism for adjusting the rotation angle is provided in the rotating member; the baking tray base plate is composed of two symmetrical plates that are movably connected; Oil storage units are respectively provided on both sides of the bottom plate connected to the rotating member, and the oil storage units are provided with a refueling port and multiple oil outlet holes; A solenoid valve (not shown in the figure) is installed at each oil outlet, and the solenoid valve is used to control the opening and closing of the oil outlet hole.

[0023] In an embodiment of the present invention, the baking pan side panel may be integrally formed, and the baking pan side panel is separated from the baking pan bottom plate and connected via a rotating member; the oil storage unit is located on the baking pan bottom plate.

[0024] In a feasible embodiment, the refueling port is arranged at the top of the oil storage unit for convenient refueling; the oil outlet is arranged on the side of the oil storage unit, and the oil outlet holes of the two oil storage units are arranged relatively to each other. There are multiple oil outlet holes, and the multiple oil outlet holes are evenly spaced. The specific number of oil outlet holes and the aperture, interval size and other parameters of the oil outlet holes can be set according to the size of the baking tray. The larger the baking tray size, the more oil outlet holes there are and the larger the aperture. On the contrary, the smaller the baking tray size, the smaller the number of oil outlet holes and the smaller the aperture.

[0025] The solenoid valve and the processor of the steam-bake combination machine can communicate wirelessly or wired. If wired communication is used, a pin header can be provided at the bottom of the baking tray base, and terminals matching the pin header can be provided on a bracket inside the steam-bake combination machine that supports the baking tray. The solenoid valve is electrically connected to the pin header via a lead wire, and the terminal is connected to the processor via a circuit. When the baking tray is placed in the steam-bake combination machine cavity, the pin header on the baking tray base inserts into the terminal of the steam-bake combination machine, thereby achieving circuit conduction and further realizing signal transmission between the processor and the solenoid valve.

[0026] The working principle of the baking tray assembly is as follows: when food is placed on the baking tray bottom plate, the food exerts pressure on the baking tray bottom plate due to its own weight. The baking tray bottom plate is connected to the rotating member. Driven by the rotating member, the two plates of the baking tray bottom plate are tilted toward the middle, generating a certain tilt angle α, such as Figure 2The figure shows a schematic diagram of one of the grill pan base panels tilted. The overall grill pan base forms a V-shaped structure. The heavier the ingredients, the greater the tilt angle of the grill pan base. When the grill pan base has a certain tilt angle, when the processor controls the solenoid valve at the oil outlet to open, the oil in the oil storage unit flows out onto the grill pan surface under the action of gravity, following the tilt angle, thus achieving automatic oil discharge.

[0027] The greater the inclination angle of the baking tray bottom plate, the greater the oil output of the oil storage unit. The principle is as follows: Based on fluid mechanics, we can estimate the equation: Q = v*h*sin(α), where Q represents the liquid flow rate, or in other words, the oil flow rate; v represents the oil flow velocity; h represents the maximum oil depth within the oil reservoir; and α represents the inclination of the baking pan. If the size of the oil outlet and the total amount of oil remain constant, the flow velocity v will change little. However, as the inclination angle increases, sinα naturally increases. Simultaneously, due to the inclination of the liquid, h also increases. This proves that, given a constant oil outlet opening time, a greater inclination angle increases the oil output from the oil reservoir.

[0028] In addition, a mechanism for adjusting the rotation angle of the rotating member, such as an elastic member, is provided in the rotating member to limit the rotation range. Assuming that in the initial state (no object on the baking tray), the inclination angle of the plate surface is α1, according to the torque of the elastic member, when the rotating member rotates to the maximum, the inclination angle of the plate surface is α2, and the baking tray surface moves between the inclination angles α1 and α2.

[0029] The specific sizes of the tilt angles α1 and α2 should be designed according to the actual size of the baking tray and the structure of the oven to ensure that the cooking oil can flow down smoothly while the ingredients will not slide off easily.

[0030] In another embodiment, the mechanism for adjusting the rotation angle of the rotating part can be set as an electronic control mechanism, and a pressure sensor is set at the bottom of the bottom plate of the baking tray. When the pressure sensor detects the weight of the food, it is transmitted to the processor. The processor determines the rotation amount of the rotating part based on the corresponding relationship between the weight of the food and the preset rotation amount of the rotating part, and sends the rotation amount to the electronic control mechanism to drive the rotating part to rotate to a certain angle, thereby realizing automatic control of the inclination angle of the baking tray.

[0031] Therefore, from the above embodiments, it can be understood that the grill pan assembly provided by the present invention produces more oil as the weight of the food increases, thereby automatically adjusting the oil output according to the weight of the food. Compared to directly configuring the grill pan base with a deformable material and using the weight of the food to apply pressure to create a certain inclination, the present invention uses a rotating member to drive the grill pan base to tilt, allowing the discharged oil to be more evenly distributed on the grill pan surface.

[0032] If the grill pan base is made of a deformable material, the base will tilt unevenly, with only a certain degree of tilt where the food is applied. Areas not under pressure will not deform or will deform only slightly, resulting in uneven distribution of oil on the grill pan surface. However, the structure of the present invention drives the grill pan base to rotate and tilt as a whole, allowing the oil to be more evenly distributed on the grill pan surface.

[0033] Based on the above embodiment, the rotating part includes a fixed part and a rotating part. The rotating part is sleeved on the outer periphery of the fixed part. The fixed part is connected to the side plate of the baking pan, and the rotating part is connected to the bottom plate of the baking pan.

[0034] In a specific embodiment, Figure 3 As shown, the fixed portion can be a columnar fixed shaft, and the rotating portion can be a hollow rotating shaft. The rotating shaft is sleeved on the fixed shaft. The length of the rotating shaft can match the length of the baking pan base, and the rotating shaft and the baking pan base can be welded together. The bottom of the baking pan side panel can form an inverted concave structure, wherein the concave portion is used to accommodate the rotating shaft, and the two ends are fixedly connected to the fixed shaft.

[0035] Based on the above embodiment, when the mechanism for adjusting the rotation angle of the rotating part is an elastic part, the elastic part adopts a torsion spring, which is sleeved on the fixed part and located between the fixed part and the rotating part; one end of the torsion spring is connected to the fixed part, and the other end is connected to the rotating part. The working principle of the torsion spring is that when the rotating shaft rotates, the torsion spring follows the rotation and generates a certain torque. Due to the nature of the torsion spring itself, when the maximum torque is reached, it will no longer follow the rotation, thereby limiting the rotation range of the rotating part and the baking tray reaches the maximum tilt angle α2; and when the ingredients on the baking tray are removed, a certain rebound force is generated, returning to the natural state, and then driving the baking tray base to return to the original tilt angle α1.

[0036] After the maximum tilt angle α2 is determined according to the actual size of the baking tray, etc., a torsion spring capable of generating a torque at the maximum tilt angle α2 is selected according to the determined maximum tilt angle α2.

[0037] On the basis of the above embodiment, a fixing member is further provided between the fixing portion and the rotating portion, and the fixing member is used to fix the rotation angle between the rotating portion and the fixing portion.

[0038] Continuing from the previous example, Figure 4 As shown, the fixing member is a hook, one end of which can be fixed on the fixed shaft, and a plurality of hanging holes are provided on the rotating shaft. When the rotating shaft rotates to a certain angle, the hook is hooked into the corresponding hanging hole, thereby fixing the angle between the rotating shaft and the fixed shaft.

[0039] Through the embodiment, the user can adjust the inclination angle a of the baking tray bottom plate by himself, and fix the angle by the fixing member when the angle is adjusted to a suitable angle. Among them, the user can find the most suitable inclination angle a of the baking tray according to his own use habit and food material.

[0040] On the basis of the above embodiment, the oil storage unit and the baking tray bottom plate are integrally formed or detachably installed.

[0041] In the embodiment of the application, when the oil storage unit and the baking tray bottom plate are integrally formed, the bottom of the oil storage unit is the bottom of the baking tray bottom plate, the rear side of the oil storage unit is the side plate, and the front side of the oil storage unit is provided with an oil outlet hole. And in the production, the oil storage unit and the baking tray body are integrally formed by injection molding process.

[0042] Through the integrally formed mode, the processing cost is lower, and the structure is simpler, but it is not convenient to clean the inside of the oil storage unit.

[0043] Therefore, the oil storage unit and the baking tray bottom plate can also be installed through a detachable structure, and the bottom of the oil storage unit is provided with buckles on both sides, and the bottom plate of the baking tray body is provided with a clamping groove matched with the buckle. Figure 5 A schematic diagram of the detachable structure of the oil storage unit and the baking tray bottom plate is shown.

[0044] In the embodiment of the application, the oil storage unit is a separate oil storage box. When the oil storage box is installed on the baking tray, the clamping groove and the buckle can be clamped with each other to fix the oil storage box on the baking tray. Similarly, the user only needs to turn the buckle to conveniently take down the oil storage box from the baking tray.

[0045] The oil storage unit and the baking tray bottom plate are installed through a detachable mode, which is convenient to detach at any time to clean the oil storage unit. And the bottom plate of the oil storage unit and the bottom plate of the baking tray are connected together, when the bottom of the baking tray body is inclined, the bottom of the oil storage unit can also be inclined with the bottom of the baking tray body.

[0046] In addition, it should be noted that in the detachable mode, the electrical devices in the oil storage unit, such as the electromagnetic valve, can communicate with the processor of the steaming and baking integrated machine through wireless communication mode, or can communicate through wired mode. Figure 5 If it is through wired mode, as shown in the figure, a pin (not shown in the figure) needs to be arranged on the bottom of the oil storage unit, and a terminal is arranged on the bottom of the baking tray bottom plate. The pin of the oil storage unit and the terminal of the baking tray bottom plate are connected through plug-in to realize circuit conduction. The baking tray bottom plate is connected through plug-in between its pin and the terminal of the steaming and baking integrated machine, and then the circuit connection between the electromagnetic valve and the processor is realized.

[0047] If the oil is left to flow slowly onto the plate, the oil can only flow toward the plate in the direction of the oil outlet hole, and can only oil the baking pan within the area covered by the oil outlet hole, so the oil outlet range is relatively limited.

[0048] Therefore, based on the above embodiment, a nozzle is provided at the oil outlet, and a pressurizing component is provided in the oil storage unit to spray the oil in the oil storage unit through the pressurizing component to form a spray.

[0049] In the embodiment of the present invention, the pressurizing component is, for example, a micro booster pump, a compressor, etc.

[0050] The pressurizing component is communicated with the processor of the steam-bake combination machine. When the solenoid valve is opened, the processor sends a driving signal to the pressurizing component, and the pressurizing component starts to work, generating pressure on the oil, driving the oil to spray out and form a spray, so that the oil spray range of the oil outlet is larger.

[0051] Based on the above embodiment, an oil collecting hole is provided at the movable connection of the two symmetrical plates, and an oil cup is installed at the bottom of the oil collecting hole.

[0052] In one possible implementation, Figure 1 As shown, the two plates are connected by a movable plate, and both ends of the movable plate are hingedly connected to the two plates. An oil collecting hole is set on the movable plate, and an oil cup is installed at the bottom of the oil collecting hole.

[0053] Based on the same inventive concept, a method for controlling oil discharge based on a baking tray assembly is provided. When food is loaded on the baking tray bottom plate, the rotating member drives the baking tray bottom plate to tilt from both sides to the middle, forming an inclination angle proportional to the weight of the food, such as Figure 6 As shown, the method includes: Step S601: Obtain the weight of the ingredients to be cooked.

[0054] In this step, a pressure sensor can be installed at the bottom of the baking tray to collect the weight of the ingredients; the weight of the ingredients can also be weighed separately through other weighing devices, and the weight information of the ingredients can be input into the processor through the operational interface on the steam-bake combination.

[0055] Step S602: Determine the target oil output of the oil storage unit based on the weight of the food and a preset mapping relationship between the weight of the food and the oil output.

[0056] In this step, the preset mapping relationship between the weight of the food and the amount of oil produced is a linear proportional relationship. The greater the weight of the food, the greater the amount of oil produced.

[0057] Step S603: determining the target inclination angle of the grill pan bottom plate based on the target oil output and a preset mapping relationship between the oil output and the inclination angle of the grill pan bottom plate.

[0058] In this step, the greater the inclination angle, the greater the oil output.

[0059] Step S604: determining the rotation angle of the rotating member on the baking tray based on the target tilt angle.

[0060] The embodiment of the present invention adjusts the oil output in the oil storage unit to the target oil output by controlling the rotation angle, thereby achieving automatic adjustment of the oil output, which avoids wasting oil and ensures the necessary amount of oil for cooking food.

[0061] In one feasible embodiment, determining the rotation angle of the rotating member on the baking tray based on the target tilt angle includes: Step S604A: determining the rotation angle of the rotating member on the baking tray based on the target tilt angle and the preset baking tray tilt range.

[0062] The minimum and maximum values ​​of the preset baking tray tilt range are set according to the size of the baking tray and the structure of the oven.

[0063] Based on the above embodiment, a solenoid valve is installed at each oil outlet, and the solenoid valve is used to control the opening and closing of the oil outlet. The method further includes: Step S605: Obtain the cooking time of the ingredients to be cooked.

[0064] The cooking time manually input or selected by the user can be obtained on the steam-bake operation interface, and the cooking time defaulted by the system according to the recipe of the ingredients to be cooked can also be obtained.

[0065] Step S606: Determine the number of oil discharges based on the cooking time.

[0066] In the embodiment of the present invention, the cooking time is proportional to the preset correspondence between the number of oil discharges. The longer the cooking time, the more oil discharges. For example, if the cooking time is 30 minutes and the oil is discharged three times, the oil discharge interval is 10 minutes.

[0067] Step S607: Determine the oil output for each oil discharge based on the target oil output.

[0068] Step S608: Determine the number of times the solenoid valve at each oil outlet is opened and closed and the duration of the opening and closing of the solenoid valve at each oil outlet based on the number of times the oil is discharged and the amount of oil discharged, and send the determined number of times and duration of the opening and closing to the corresponding solenoid valve.

[0069] When the solenoid valve is opened, the oil in the oil storage unit flows out onto the disk surface along an inclined angle.

[0070] The number of times the solenoid valve is open is the same as the number of times oil is discharged. The longer the solenoid valve is open, the more oil is discharged. When the solenoid valve is open for the same amount of time, the greater the tilt angle of the baking tray, the greater the oil discharge. The present application determines the oiling frequency according to the cooking time of different food materials, and automatically adjusts the oiling amount according to the inclination angle proportional to the weight of the food material, so as to automatically adjust the oiling amount and frequency of different weights and types of food materials, and improve the cooking effect.

[0071] In another possible implementation, the oiling frequency can also be determined according to the maturity of the food, specifically including the following steps: Step A: acquiring an image of the food material by an image acquisition device.

[0072] Step B: determining the maturity of the food material based on the image.

[0073] In which, the maturity of the food material is determined based on the image, and many existing technologies have realized this means, for example, using a pre-trained neural network model, which is not described here.

[0074] Step C: determining whether the maturity of the food material is greater than or equal to a preset maturity threshold.

[0075] If greater than or equal to, the baking tray starts to execute the oiling program. If less than the preset maturity threshold, return to step A.

[0076] In which, if the recipe cooking time is long, multiple maturity thresholds can be set for multiple oiling.

[0077] When using the oiling function of the baking tray, there is a problem that needs attention. When the user is preparing the food material, there may be more water on the food material or more water remaining on the baking tray. When the steaming and baking all-in-one machine is working, if the temperature in the cavity is high and there is more water remaining on the food material or the baking tray, when the baking tray is oiled, the oil may splash due to the contact between the oil and the water, which is commonly known as "frying pot".

[0078] In order to avoid the "frying pot" situation of cooking oil at high temperature, a heating fan can be provided in the steaming and baking all-in-one machine, which mainly functions to circulate the hot air in the all-in-one machine, so that the food material in the baking tray is evenly heated. At the same time, it can also dry the food material and remove excess water in the food material.

[0079] On the basis of the above embodiment, before sending the opening and closing times and the opening and closing time length to the electromagnetic valve, the method further includes: Step D: acquiring image information of the baking tray and the food material by an image acquisition device.

[0080] Because the operating environment is high, the image acquisition device must also possess excellent heat resistance to ensure long-term stable operation. This image acquisition device is typically a high-temperature-resistant camera. For example, an industrial-grade, high-temperature-resistant camera can be used: These cameras are specifically designed for use in high-temperature environments and offer excellent heat resistance and protection levels. For example, certain IP67 or IP68-rated industrial cameras are not only waterproof and dustproof, but can also withstand high temperatures.

[0081] Step E: Detect the moisture content of the baking tray and ingredients based on the image information.

[0082] In this step, a model trained with a large amount of labeled data can be used to identify and distinguish images of food with different moisture contents. For example, a convolutional neural network (CNN) is used to extract features from images and perform classification.

[0083] Step F: If the image information shows that there is excess moisture, a turn-on command is sent to the fan of the steam-bake combination machine to dry out the excess moisture.

[0084] Based on the same inventive concept, a steam-bake combination machine is provided, comprising a steam-bake combination machine body, a processor and a baking tray assembly as described in any one of the first aspects, wherein the processor is communicatively connected to the solenoid valve of the baking tray assembly.

[0085] In a possible embodiment, the steam-bake machine further includes a heating fan for drying excess moisture on the baking tray to prevent the pan from frying.

[0086] In a possible embodiment, the steam-bake machine is further installed with an image acquisition device for acquiring image information of the food on the baking tray.

[0087] In addition, by combining the steam baking mode of the steam-bake machine with the automatic oil-discharging function of the baking tray, it is also possible to achieve pan-frying (or pan-frying) of the opposite side.

[0088] Steam baking in a steam-bake combination oven is an existing technology. The principle is that when the oven is baking, a steam generator inside the oven cavity draws water from a water tank and sprays it into the pot in the form of steam. Simply adjusting the steam generator's spray angle or replacing the steam generator with a pipe valve can add water to the baking tray.

[0089] Pan-fried and pan-fried dumplings are commonplace in our daily lives, known for their crispy, juicy, and delicious flavors, making them incredibly popular. However, their preparation can be complex. To create beautiful and delicious pan-fried dumplings, the pan often requires repeated refilling and re-adding oil, and the heat control required is also challenging. These two complex cooking methods are difficult for most users to master. The automatic refilling function of the baking tray and the steam baking function of the steam-bake combination make it easy to add both oil and water.

[0090] When frying, if there is an oil collecting tank or oil collecting hole on the baking tray, the user needs to place the matching cover on the oil collecting tank or oil collecting hole to prevent water and oil from being lost from the baking tray.

[0091] The user then places the prepared pastries evenly on the baking tray (if the user needs to make good-looking dough, they can also add appropriate amount of flour and water to the baking tray first).

[0092] The baking tray will be regularly replenished with water and oil according to the settings of the recipe program to keep sufficient water and oil in the pot for the best cooking effect.

[0093] As long as there is enough water and oil in the baking pan, you can achieve pan-frying and pan-frying, enriching the user's cooking experience.

[0094] The oven also uses an image acquisition device to automatically identify the remaining water and oil in the baking tray and replenish them promptly if they are running low. Compared to manual cooking, this solution allows for better control of the baking tray's temperature and ensures a constant supply of water and oil, resulting in better cooking results.
