Technical Field

[0001] This invention relates to the field of food processing equipment technology, and in particular to an oven and its control method, control system and control device. Background Technology

[0002] With the increasing popularity of home ovens, people have more and more demands for their functions, and multi-functionality has become the mainstream trend. To achieve a charcoal-grilled flavor and the effect of traditional grilling, a common method for home ovens is to add a smoke box inside. However, this requires an additional heating element, which inevitably reduces the usable internal volume of the oven without increasing its overall size.

[0003] In conclusion, how to increase the usable volume inside an oven has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0004] The purpose of this invention is to provide an oven and its control method, control system and control device to increase the usable volume inside the oven.

[0005] To achieve the above objectives, the present invention provides a control method for an oven, applicable to an oven having an internal evaporation tray, wherein the top surface of the evaporation tray has a loading slot for holding water, and the interior of the evaporation tray is provided with an auxiliary heater for heating the contents loaded in the loading slot, wherein a smoke generator can be embedded in the loading slot. The control method includes: in response to a smoking mode command, controlling the auxiliary heater to heat the smoke generator to a smoke temperature.

[0006] Preferably, the smoke-generating temperature is 250℃-300℃.

[0007] Preferably, the auxiliary heater is controlled to heat the smoke-generating box to the smoke-generating temperature according to the following steps:

[0008] Step S1: Control the auxiliary heater to remain powered on for a first preset time so that the heating temperature of the auxiliary heater reaches the smoke emission temperature;

[0009] Step S2: After controlling the auxiliary heater to remain in a power-off state for a second preset time, return to execute step S1.

[0010] Preferably, the first preset duration is 1 minute to 3 minutes, and the second preset duration is 4 minutes to 6 minutes.

[0011] Preferably, the control method further includes: in response to a steam-bake mode command, controlling the auxiliary heater to heat the water loaded in the loading tank to the evaporation temperature.

[0012] Preferably, the control method further includes: acquiring the oven's operating mode, and generating a corresponding operating mode instruction based on the oven's operating mode, wherein the operating mode instruction includes a smoked / roasted mode instruction and a steamed / roasted mode instruction.

[0013] Preferably, the method of obtaining the oven's working mode includes: obtaining the working mode input by the user; and / or, detecting the functional auxiliary material loaded in the loading slot to determine the current pre-entry working mode. If the functional auxiliary material is water, the working mode is a steam-roast mode; if the functional auxiliary material is a smoke generator, the working mode is a smoke-roast mode.

[0014] Compared to the background description, the oven control method described above is applied to an oven with an internal evaporator plate. The top surface of the evaporator plate has a loading slot for holding water. An auxiliary heater is installed inside the evaporator plate to heat the contents loaded in the loading slot. A smoke generator can be embedded in the loading slot. The control method includes: responding to a smoking mode command, controlling the auxiliary heater to heat the smoke generator to a smoking temperature. With this control method, when the oven needs to perform a smoking operation, only the smoke generator needs to be placed in the loading slot, and then the auxiliary heater in the evaporator plate is controlled to heat the smoke generator to the smoking temperature. No additional heating device is needed for the smoke generator, thus helping to increase the usable volume inside the oven. Simultaneously, the auxiliary heater heats the smoke generator through the loading slot, and since the smoke generator is embedded in the loading slot, it also helps to increase the usable volume inside the oven.

[0015] In addition, the present invention also provides a control system for an oven, including a main heater, an auxiliary heater, and a controller. The main heater is used to bake the food inside the oven cavity; the auxiliary heater is used to heat the functional auxiliary materials loaded in the loading slot of the evaporator tray; the controller is used to control the main heater and the auxiliary heater to perform heating operations, and the controller can control the auxiliary heater to perform heating operations according to the oven control method described in any of the above embodiments.

[0016] Since the control system has a controller capable of controlling the auxiliary heater to perform heating work according to the aforementioned control method, and the aforementioned control method has the above-mentioned technical effects, the control system should also have the corresponding technical effects, which will not be elaborated here.

[0017] Preferably, the control system further includes a control panel disposed on the outside of the oven and communicatively connected to the controller, the control panel being provided with function buttons, including steam-roast buttons and smoke-roast buttons.

[0018] Furthermore, the present invention also provides a control device for an oven, applied to an oven having an internal evaporator plate. The top surface of the evaporator plate forms a loading groove for holding water. An auxiliary heater for heating the contents loaded in the loading groove is disposed inside the evaporator plate. A smoke generator can be embedded in the loading groove. The control device includes an acquisition unit and a control unit. The acquisition unit is used to acquire an oven operating mode command, including a smoking / roasting mode command. The control unit, in response to the smoking / roasting mode command, controls the auxiliary heater to heat the smoke generator to the smoke temperature. Since this control device has the same core idea as the aforementioned control method, it should also have corresponding technical effects, which will not be elaborated further here.

[0019] In addition, the present invention also provides an oven, wherein the oven includes the control system described in any of the foregoing solutions. Since the aforementioned control system has the above-mentioned technical effects, the oven having the control system should also have the corresponding technical effects, which will not be elaborated further here.

[0026] The core of this invention is to provide an oven and its control method, control system and control device to increase the usable volume inside the oven.

[0027] To enable those skilled in the art to better understand the technical solutions provided by this invention, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0028] like Figure 1 As shown, this embodiment of the invention provides a control method for an oven, applied to an oven 1 having an evaporation plate 2 inside. The top surface of the evaporation plate 2 is formed with a loading groove 3 for holding water, and a smoke box 4 can be embedded in the loading groove 3. An auxiliary heater is provided inside the evaporation plate 2 for heating the functional auxiliary materials loaded in the loading groove 3.

[0029] It should be noted that the specific form of the functional auxiliary material loaded in the aforementioned loading tank is as follows: when the oven is used for steaming and baking, the functional auxiliary material can be water placed in the loading tank 3; when the oven is used for smoking and baking, the functional auxiliary material can be a smoke box 4 placed in the loading tank 3.

[0030] See Figure 2 As shown, the control method specifically includes: in response to the smoking mode command, controlling the auxiliary heater to heat the smoke box 4 to the smoke temperature.

[0031] With this control method, when the oven needs to perform a smoking operation, it is only necessary to place the smoke box into the loading slot, and then control the auxiliary heater in the evaporation plate to heat the smoke box to the smoking temperature. There is no need to configure an additional heating device for the smoke box, which helps to increase the usable volume inside the oven. At the same time, the auxiliary heater heats the smoke box through the loading slot. Since the smoke box is embedded in the loading slot, it also helps to increase the usable volume inside the oven.

[0032] It should be noted that those skilled in the art should understand that if the functional auxiliary material loaded in the loading tank 3 is water, in order to achieve the evaporation of the water loaded in the loading tank 3 so that the oven can achieve the steaming function, the heating temperature of the auxiliary heater is generally set to 120℃±10℃.

[0033] If the smoke generator box loaded in loading slot 3 is a fruitwood-type smoking box, considering that the smoldering temperature of fruitwood is usually between 250℃ and 300℃, the smoke generation temperature of the aforementioned smoke generator box is generally also between 250℃ and 300℃. It is understood that the smoke generator box is not limited to a fruitwood-type smoking box; it can also be a liquid smoking box. In practical applications, the appropriate type can be selected based on actual needs. Of course, those skilled in the art should understand that the smoke generator box needs to be placed in the loading slot before the oven performs the smoking operation.

[0034] In some specific implementations, this control method controls the auxiliary heater to heat the smoke-generating box 4 to the smoke-generating temperature according to the following steps:

[0035] Step S1: Control the auxiliary heater to remain powered on for a first preset time so that the heating temperature of the auxiliary heater reaches the smoke generation temperature of the smoke generation box;

[0036] Step S2: After controlling the auxiliary heater to remain in the power-off state for a second preset time, return to step S1.

[0037] The heating time of the auxiliary heater in the evaporation pan is controlled by the oven's main control board. Generally, the first preset time is set to 1-3 minutes, and the second preset time is set to 4-6 minutes. In actual application, the setting can be made according to the factory settings or by the user according to the type of functional auxiliary material and the performance of the auxiliary heater itself.

[0038] Through theoretical and practical testing, this invention has determined that the heating time is 2 minutes (i.e., the first preset duration), during which the temperature inside the lower cover of the smoke box can rise to 300°C. Then, the power is turned off for 5 minutes (i.e., the second preset duration). Relying on residual heat, the temperature inside the lower cover can reach a maximum of about 320°C. At this temperature, it can be ensured that the fruitwood inside the smoke box only produces smoke without burning, while ensuring that there is sufficient smoke in the oven cavity to smoke and roast the food. The heating time is repeated in this cycle.

[0039] To help those skilled in the art better understand the technical solution of the present invention, the following is combined with... Figure 3 The specific control process for controlling the auxiliary heater to heat the smoke box 4 to the smoke temperature is explained below:

[0040] Step S201: Control the auxiliary heater to keep it powered on;

[0041] Step S202: Determine whether the power-on time has reached the first preset time (e.g., 2 minutes). If yes, proceed to step S203; otherwise, return to step S201.

[0042] Step S203: Control the auxiliary heater to remain in a de-energized state;

[0043] Step S204: Determine whether the interruption duration has reached the second preset duration (e.g., 5 minutes). If yes, proceed to step S205; otherwise, return to step S203.

[0044] Step S205: Determine whether the smoking operation is complete (the specific time can be set). If yes, proceed to step S206; otherwise, return to step S201.

[0045] Step S206: End.

[0046] In some more specific implementations, the control method may further include: in response to a steam-bake mode command, controlling an auxiliary heater to heat the water loaded in the loading tank to the evaporation temperature.

[0047] In a further implementation, the control method further includes: acquiring the oven's operating mode, and generating a corresponding operating mode instruction based on the oven's operating mode. The operating mode instruction includes a smoking / roasting mode instruction and a steaming / roasting mode instruction, but is not limited to these two operating mode instructions.

[0048] It should be noted that the specific way to obtain the oven's working mode is to obtain the working mode input by the user. The oven is equipped with a corresponding input module for the user to input the corresponding working mode. The user input method can be button input or voice input, and no specific limitation is made here.

[0049] It's understandable that the oven's operating mode could be determined by detecting the functional additives loaded in the loading slot. If the additive is water, the operating mode is steam-bake; if it's a smoke generator, the mode is smoke-roast. Detecting the additives could involve installing a corresponding trigger switch within the slot. When a smoke generator is placed in the slot, it triggers the switch, activating the corresponding circuit and indicating that the additive is a smoke generator. Alternatively, an image acquisition device could capture images of the loading slot's location, comparing the captured images with pre-stored images to determine the specific additive. In practical applications, this can be customized to meet specific needs.

[0050] In addition, the present invention also provides a control system for an oven, including a main heater, an auxiliary heater, and a controller. The main heater is used to bake the food inside the inner cavity of the oven 1; the auxiliary heater is used to heat the functional auxiliary materials loaded in the loading slot 3 of the evaporation tray 2; the controller can control the auxiliary heater to perform heating work according to the oven control method described in any of the above schemes.

[0051] Since the control system has a controller capable of controlling the auxiliary heater to perform heating work according to the aforementioned control method, and the aforementioned control method has the above-mentioned technical effects, the control system should also have the corresponding technical effects, which will not be elaborated here.

[0052] In some more specific implementations, the control system may further include a control panel located outside the oven 1 and communicatively connected to the controller. The control panel has function buttons, including steam-bake and smoke-bake buttons. Users can directly select and input the corresponding operating mode commands via the function buttons, making operation more convenient and simple. Of course, it is understood that other input methods can also be used in practical applications, such as a voice module communicatively connected to the controller, allowing users to input via voice.

[0053] In addition, such as Figure 4 As shown, the present invention also provides a control device for an oven, applied to an oven 1 having an evaporator 2 inside. The top surface of the evaporator 2 forms a loading groove 3 for holding water. An auxiliary heater is provided inside the evaporator 2 for heating the contents loaded in the loading groove 3. A smoke box 4 can be embedded in the loading groove 3. The control device includes an acquisition unit and a control unit. The acquisition unit is used to acquire the working mode command of the oven 1, which may specifically include a smoking mode command, but is not limited to a smoking mode command. The control unit, in response to the smoking mode command, controls the auxiliary heater to heat the smoke box 4 to the smoking temperature. Since this control device has the same core idea as the aforementioned control method, it should also have corresponding technical effects, which will not be elaborated here.

[0054] In addition, the present invention also provides an oven, wherein the oven includes the control system described in any of the foregoing solutions. Since the aforementioned control system has the above-mentioned technical effects, the oven having the control system should also have the corresponding technical effects, which will not be elaborated further here.
