[0033] The present application provides an embodiment of a steam oven with a detachable heating container, in which the heating container is detachable from the main structure of the steam oven. When it is necessary to clean the heating container, it can be taken out of the steam oven for cleaning, which can improve the convenience of impurity cleaning. It should be noted that the steam oven with a detachable heating container in the embodiments of the present application can also have the function of an oven. When it has the function of an oven, it can also be called a steam oven with a detachable heating container and oven function.

[0034] Please refer to Figure 1 , Figure 1It is a schematic diagram of the result of the detachable steam oven with a heating container provided by an embodiment of the present application. The detachable steam oven with a heating container includes a control system 10 and an electromagnetic heating unit 20. The electromagnetic heating unit 20 includes a coil disk 201, a black crystal panel 202, and a heating container 203. The container wall and / or the container bottom of the heating container 203 is / are made of metal.

[0035] The control system 10 can be an electromagnetic heating control board (also known as an IH heating control board) inside the steam oven.

[0036] The heating container 203 can be, but is not limited to, a kind of cookware, and the top opening of the cookware can form a preset slope. In an optional embodiment, both the container wall and the container bottom of the heating container 203 are made of metal, which can improve the effect of electromagnetic cutting and enhance the heating efficiency.

[0037] Please refer to Figure 2 , Figure 2 It is a schematic diagram of the structure of the electromagnetic heating unit provided by an embodiment of the present application.

[0038] The black crystal panel 202 is arranged above the coil disk 201, and the heating container 203 is detachably arranged on the black crystal panel 202. The coil disk 201 is connected to the control system 10 (not shown in the figure).

[0039] It should be noted that the black crystal panel 202 can play a supporting role, and the heating container 203 can be directly placed on the black crystal panel 202. The black crystal panel 202 can also play a heat insulation effect between the coil disk 201 and the heating container 203.

[0040] The coil disk 201 includes a plurality of coils, and the coils can be, but are not limited to, copper wires or copper-clad aluminum wires. The coil disk 201 is also provided with a terminal block, and the control system 10 can be connected to the terminal block of the coil disk 201. The control system 10 can control the current on the coil disk 201, including switching the current direction and changing the current magnitude, so that the coil disk 201 can heat the heating container 203 by electromagnetic induction.

[0041] The control system 10 is used to control the coil disk 201 (i.e., switch the current direction and / or change the current magnitude) to heat the heating container 203 by electromagnetic induction.

[0042] It should be noted that the outer shell of the steam oven or steam oven with grill is generally a metal part. In order to avoid or reduce the electromagnetic induction between the magnetic field of the coil disk 201 and the outer shell of the steam oven or steam oven with grill, a shield needs to be arranged between the coil disk 201 and the outer shell.

[0043] It should be noted that the control system 10 can adjust the heating efficiency by changing the current.

[0044] Optionally, the electromagnetic heating unit 20 further includes a shield, which is disposed below the coil disk 201. Please continue to refer to Figure 2 , Figure 2 The shield shown in includes an aluminum plate 204, and the aluminum plate 204 is disposed between the coil disk 201 and the housing.

[0045] In an optional embodiment, the shield includes a bottom magnetic strip 205, and the bottom magnetic strip 205 is disposed on the side of the coil disk 201 close to the housing.

[0046] In an optional embodiment, the shield includes the aluminum plate 204 and the bottom magnetic strip 205.

[0047] As Figure 1 shown, the electromagnetic heating unit 20 can be disposed at the bottom of the detachable steaming oven of the heating container. The bottom of the detachable steaming oven of the heating container is further provided with a first heat dissipation air duct (not shown in the figure). The detachable steaming oven of the heating container further includes a heat dissipation fan (not shown in the figure). The air outlet of the heat dissipation fan corresponds to one end of the first heat dissipation air duct, and the other end of the first heat dissipation air duct corresponds to the coil disk 201.

[0048] It should be noted that during the heating process, the temperature of the coil disk 201 will also rise. If the temperature of the coil disk 201 is too high, it may affect the heating efficiency of the steaming oven. Therefore, heat dissipation design is required for it.

[0049] In an optional embodiment, the detachable steaming oven of the heating container is further provided with a second heat dissipation air duct, which is used to communicate the heat dissipation fan with the control system 10 to dissipate heat from the control system 10.

[0050] When the steaming oven or steam oven is working, it is often necessary to monitor its working state and adjust the control strategy in a timely manner according to the monitoring information, such as adjusting the heating power and replenishing water to the heating container. The monitoring information includes any one or more of the oxygen amount in the heating cavity of the detachable steaming oven of the heating container, the bottom temperature of the heating container of the detachable steaming oven of the heating container, and the water consumption of the heating container within a preset time period.

[0051] Please continue to refer to Figure 1 , in an optional embodiment, the detachable steaming oven of the heating container further includes an oxygen sensor 30, and the oxygen sensor 30 is disposed in the heating cavity of the detachable steaming oven of the heating container. The oxygen sensor 30 is connected to the control system 10.

[0052] The oxygen sensor 30 can obtain the oxygen content in the heating cavity and transmit the monitored oxygen content to the control system 10.

[0053] Please continue to refer to Figure 1, in an alternative embodiment, the detachable heating container steam box further includes a temperature sensor 40. The temperature sensor 40 is disposed on the side of the black crystal panel 202 away from the heating container 203, and the temperature sensor 40 is connected to the control system 10.

[0054] In an alternative embodiment, as Figure 2 shown, the center of the coil disk 201 is in a vacant state, and the temperature sensor 40 can be disposed at the center of the coil disk 201.

[0055] The temperature sensor 40 can but is not limited to using a thermistor (abbreviation, NTC).

[0056] The temperature sensor 40 is used to collect the bottom temperature of the heating container 203 and transmit the collected temperature information to the control system 10. The control system 10 can calculate the temperature change slope (also known as the NTC dry burning slope) at the current time period based on the received temperature information.

[0057] Please continue to refer to Figure 1 , in an alternative embodiment, the detachable heating container steam box further includes a water tank 50 and a water supply pipe (not shown in the figure). The water supply pipe is provided with a water valve, and the water valve is connected to the control system 10.

[0058] One end of the water supply pipe is connected to the water outlet of the water tank, and the other end of the water supply pipe is connected to the water inlet 203-1 of the heating container 203.

[0059] The control system 10 can control the water tank 50 to replenish water to the heating container 203 by switching the state of the water valve (open or closed), that is, control the water inlet of the heating container.

[0060] Alternatively, the detachable heating container steam box further includes a water tank 50 and a water pump. The water inlet end of the water pump communicates with the water tank 50, and the water outlet end of the water pump communicates with the water inlet 203-1 of the heating container 203. The water pump is connected to the control system 10, and the control system 10 can control the water pump to work to pump the water in the water tank 50 into the heating container 203, that is, control the water inlet of the heating container.

[0061] In an alternative embodiment, after the control system 10 is powered on (or at a preset interval), it sends a pulse signal to the coil disk 201 for pulse detection to determine whether a heating container 203 is placed on the black crystal panel 202.

[0062] Optionally, the detachable heating container steam box further includes an operation display screen 60, and the control system 10 is connected to the operation display screen 60.

[0063] When it is recognized that a heating container 203 is placed on the black crystal panel 202, the control system 10 can control the steaming function icon on the operation display screen 60 to light up. Conversely, when it is recognized that no heating container 203 is placed on the black crystal panel 202, the control system 10 can control the steaming function icon on the operation display screen 60 to go out.

[0064] On the basis of the foregoing, with regard to how the control system 10 controls the water supply to the heating container 203, an optional implementation manner is further provided in an embodiment of the present application. Please refer to the following text.

[0065] The control system 10 is configured to add water to the heating container 203 according to the current oxygen amount and the target oxygen amount in the heating cavity of the detachable steaming oven of the heating container.

[0066] It should be noted that the oxygen sensor 30 can transmit the collected oxygen amount to the control system 10. Therefore, the control system 10 can obtain the initial oxygen amount in the heating cavity before heating and the current oxygen amount in the heating cavity.

[0067] When the deviation between the target oxygen amount and the current oxygen amount is greater than a preset amplitude, it is determined that the water addition condition is satisfied, and water can be added to the heating container 203.

[0068] Optionally, the target water addition amount that needs to be added to the heating container 203 can also be based on the target oxygen amount and the current oxygen amount.

[0069] Alternatively, the control system 10 is configured to add water to the heating container 203 according to the bottom temperature of the heating container 203.

[0070] Optionally, the control system 10 is configured to calculate the temperature change slope at the current time period according to the received temperature information (the bottom temperature of the heating container 203). When the temperature change slope is greater than a preset slope, it indicates that the temperature rises too fast. At this time, dry burning may occur. It is determined that the water addition condition is satisfied, and water can be added to the heating container 203.

[0071] Alternatively, the control system 10 is configured to add water to the heating container 203 according to the water consumption of the heating container 203 within a preset time period.

[0072] Optionally, during the heating process, the water consumption of the heating container 203 within a preset time period is obtained according to the heating power of the electromagnetic heating unit 20. When the cumulative value of the water consumption is greater than a preset water consumption, it is determined that the water addition condition is satisfied, and water can be added to the heating container 203. At the same time, the cumulative value of the water consumption can be cleared, and the cumulative value of the water consumption can be re - counted. The cumulative value of the water consumption is the cumulative water consumption corresponding to the electromagnetic heating unit 20 since the last water addition.

[0073] In an alternative embodiment, the control system 10 can also determine the steam demand according to the recipe selection instruction, calculate by combining the energy efficiency and heating power of the electromagnetic heating unit 20, and can determine the target total water volume. Then, in combination with the capacity of the heating container 203 and the target total water volume, water is added to the heating container 203.

[0074] On the basis of the foregoing, in order to ensure continuous and uninterrupted heating steam, an alternative embodiment is also provided in the embodiments of the present application. Please refer to the following text.

[0075] The control system 10 is used to divide the target water addition volume into at least two portions and add water to the heating container 203 in batches at preset time intervals.

[0076] The target water addition volume can be pre-configured or calculated through monitoring information and / or heating efficiency. It should be noted that when an excessive amount of water is added to the heating container 203 at one time, the temperature in the heating container 203 may drop suddenly, resulting in a temperature that is not sufficient to generate steam for a period of time, leading to a situation of interrupted steam.

[0077] In the present application, the target water addition volume is divided into at least two portions, and water is added to the heating container 203 in batches at preset time intervals, reducing the single water addition volume, so that water is continuously added intermittently when the water boils, keeping the water temperature in the container from dropping and preventing steam interruption.

[0078] Optionally, the water addition volume for each batch can be related to the heating efficiency and / or the remaining water volume in the heating container.

[0079] In summary, a detachable steaming oven with a heating container provided in the embodiments of the present application includes a control system and an electromagnetic heating unit. The electromagnetic heating unit includes a coil disk, a black crystal panel, and a heating container. The container wall and / or the container bottom of the heating container is made of metal; the black crystal panel is arranged above the coil disk, the heating container is detachably arranged on the black crystal panel, and the coil disk is connected to the control system; the control system is used to control the coil disk and heat the heating container by electromagnetic induction.
