[0045] To more clearly illustrate the technical solutions of the embodiments of the present invention, the following briefly describes the drawings required for describing the embodiments. Obviously, the drawings described below are merely examples or embodiments of the present invention. Those skilled in the art can apply the present invention to other similar scenarios based on these drawings without inventive effort. Unless otherwise apparent from the context or otherwise noted, the same reference numerals in the figures represent the same structure or operation.

[0046] As used herein and in the claims, unless the context clearly indicates otherwise, the terms "a," "an," "an," and / or "the" are not intended to refer to the singular but may include the plural. Generally speaking, the terms "comprises" and "include" only indicate the inclusion of the steps and elements specifically identified, and these steps and elements do not constitute an exclusive list. A method or apparatus may also include other steps or elements.

[0047] Although the present invention makes various references to certain modules in the system according to an embodiment of the present invention, any number of different modules can be used and run on a computing device and / or processor. The modules are only illustrative, and different aspects of the system and method can use different modules.

[0048] It should be understood that when a unit or module is described as being "connected" or "coupled" to other units, modules, or blocks, it can refer to being directly connected or coupled, or communicating with other units, modules, or blocks, or there can be intervening units, modules, or blocks, unless the context clearly indicates otherwise. As used herein, the term "and / or" may include any and all combinations of one or more of the associated listed items.

[0049] The present application embodiment provides an oven, such as Figure 1 As shown, the oven includes an inner pot, multiple layers of side supports for placing baking trays in the inner pot, a temperature detection unit 100 and a heating tube 200 arranged near the side supports, and a control module 300, and the baking tray and the side supports have different specific heat capacities.

[0050] Because the specific heat capacities of the baking tray and the side rack are different, the temperature change rate of the side rack with the baking tray placed on it is different from the temperature change rate of the side rack without the baking tray placed on it. Based on this, the control module 300 can determine the detection result of whether a baking tray is placed on the side rack of each layer based on the respective temperature change rates.

[0051] For example, if the baking tray is made of steel and the side racks are made of ceramic, the specific heat capacity of steel is greater than that of ceramic. Therefore, when heated evenly and normally, the baking tray will heat up slower than the side racks. Therefore, the side racks holding the baking tray will heat up slower than the side racks without the baking tray.

[0052] The actual heating temperature of food can vary depending on the number of baking trays or the number of baking trays. For example, at the same preset temperature, a baking tray on the third layer, farther from the heating tube 200, may actually be 4°C below the preset temperature, while a baking tray on the first layer may be 1°C below the preset temperature. Furthermore, the greater the number of baking trays, the further the actual heating temperature will deviate from the preset temperature.

[0053] Based on the above analysis, the control module 300 determines the corresponding target temperature based on the detection results, i.e., the number of layers and the quantity of the baking trays, to compensate for the preset temperature, so as to control the heating tube 200 to heat to the target temperature, thereby achieving a better cooking effect.

[0054] In some embodiments, as Figure 2As shown, the temperature detection unit 100 includes a plurality of temperature sensors (T1, T2 to Tn) connected in parallel, and each of the temperature sensors is respectively arranged close to the side support of the corresponding layer.

[0055] The control module 300 uses the temperature data detected by each temperature sensor to obtain the temperature change rate of each layer of the side support.

[0056] In some embodiments, as Figure 3 As shown, the temperature detection unit 100 includes multiple temperature detection circuits connected in parallel, each of which includes a thermistor component (R1, R2~Rn) and a current sensor (A1, A2~An) connected in series, and each of the thermistor components is arranged near the side bracket of the corresponding layer.

[0057] The resistance of the thermistor component increases as the temperature rises, so the resistance change rate of the thermistor component can represent the temperature change rate of the side bracket, and its resistance change rate affects the current change rate of the temperature detection circuit. Therefore, the control module 300 can obtain the current change rate detected by each current sensor to represent the temperature change rate of each layer of the side bracket.

[0058] In some embodiments, the heating tube is a thermistor, whose resistance increases with increasing temperature.

[0059] In a pure resistance circuit, the greater the resistance, the smaller the heat generated. The advantage of this is that when the temperature reaches the preset temperature, the heat generated is reduced to protect the heating tube. When the inner tank just starts working, the inside is cold. If the heating tube is a thermistor, the heating speed will be slower in the later stage and the speed of reaching the preset temperature will be slower. In this way, there will be more sufficient heating time to allow the inner tank to heat evenly, and the area far away from the heating tube position can also be heated up.

[0060] like Figure 4 As shown, an embodiment of the present application provides a heating control method for an oven, which is applied to the above-mentioned oven and specifically includes the following steps:

[0061] S402: During the heating process of the oven, using the temperature detection unit to obtain the temperature change rate of the side brackets at each layer;

[0062] S404: Determining, based on the temperature change rates, whether a baking tray is placed on the side brackets of each layer;

[0063] S406: Determine a corresponding target temperature based on the detection result to control the heating tube to heat to the target temperature.

[0064] Based on the above steps S402-S406, during the oven heating process, this embodiment uses the temperature detection unit to obtain the temperature change rate of the side racks on each layer; based on each temperature change rate, the detection result of whether a baking tray is placed on the side racks on each layer is determined; based on the detection result, the corresponding target temperature is determined to control the heating tube to heat to the target temperature to achieve a better cooking effect.

[0065] In one exemplary embodiment, the specific heat capacity of the baking pan is greater than that of the side bracket. For example, the baking pan is made of steel and the side bracket is made of ceramic. In this case, if the temperature change rate is less than a temperature change rate threshold, it is determined that a baking pan is placed on the side bracket at the corresponding level. Otherwise, it is determined that no baking pan is placed on the side bracket at the corresponding level.

[0066] In one embodiment, if Figure 5 As shown, determining the corresponding target temperature based on the detection result includes:

[0067] S502: Determine a corresponding compensation temperature based on the detection result;

[0068] S504: Determine the target temperature based on the compensation temperature and the preset temperature.

[0069] The detection result includes the layer number of the baking tray and the number of baking trays. The higher the layer number of the baking trays, the greater the compensation temperature, and the greater the number of baking trays, the greater the compensation temperature.

[0070] The target temperature is obtained by compensating the preset temperature with the compensation temperature. The target temperature can be understood as the latest cooking temperature of the food, thereby achieving a better cooking effect.

[0071] In an exemplary embodiment, the heating control method of the oven is as follows Figure 6As shown, in this example embodiment, the baking tray is made of steel, the side supports are made of ceramic, and the temperature detection unit includes three parallel-connected temperature detection circuits, each of which includes a thermistor and a current sensor connected in series. Before the oven heats up, the user selects a preset temperature, which then controls the operation of the heating element. When the temperature inside the liner reaches the preset temperature, the current sensor measures the rate of change of the current in each temperature detection circuit: V1, V2, and V3, corresponding to the first, second, and third side supports, respectively. The current change rate corresponding to the side bracket without a baking tray is V. Compare V1, V2, and V3 with V respectively. If V1 < V, V2 < V, and V3 < V, then baking trays are placed on the first, second, and third side brackets, and the compensation temperature is 5°C; if V1 < V, V2 < V, and V3 ≥ V, then baking trays are placed on the first and second side brackets, and the compensation temperature is 2°C; if V1 < V, V2 ≥ V, and V3 < V, then baking trays are placed on the first and third side brackets, and the compensation temperature is 3°C; if V1 < V, V2 ≥ V, and V If V1≥V, V2<V, and V3<V, a baking tray is placed on the first rack and the compensation temperature is 1°C. If V1≥V, V2<V, and V3<V, baking trays are placed on both the second and third racks and the compensation temperature is 4°C. If V1≥V, V2<V, and V3≥V, a baking tray is placed on the second rack and the compensation temperature is 3°C. If V1≥V, V2≥V, and V3<V, a baking tray is placed on the third rack and the compensation temperature is 4°C. If V1≥V, V2≥V, and V3≥V, no baking tray is placed on any of the three racks and the compensation temperature is -5°C. After determining the compensation temperature, the target temperature is calculated to control the operation of the heating element, thereby achieving better cooking results.
