[0056] In another exemplary embodiment, the temperature detection assembly further comprises two second temperature sensors 102.
[0057] In order to adapt to different placement positions of the cooking accessories 40 and to quickly and accurately respond to the temperature of the target area on the two sides of each cooking accessory 40, the detection accuracy and control accuracy of the temperature inside the baking cavity 11 are improved, the temperature of the oven is accurately controlled to reach the target value, the two second temperature sensors 102 are arranged in the baking space between the cooking accessory 40 and the first heating element 20 and the baking space between the cooking accessory 40 and the second heating element 30, and the first temperature sensor 101 is arranged in the baking space 111 between the cooking accessories 40.
[0058] Among them, the first temperature sensor 101 is arranged in the baking space between the cooking accessories, and the first temperature sensor 101 can be accommodated in the accommodating portion 13 to reduce the probability of interference between the cooking accessory 40 and the first temperature sensor 101.
[0059] Please refer again to Figure 1 and Figure 2As shown, in one specific embodiment, the oven comprises three cooking accessories 40, three mounting portions 50 are arranged on the side wall 123 in sequence and at intervals along the height direction of the oven, and the three cooking accessories 40 are respectively mounted on the mounting portions 50 in a pull-out manner, and the baking cavity 11 is divided into a first baking space, a second baking space, a third baking space and a fourth baking space from top to bottom. The first temperature sensor 101 comprises a first one temperature sensor 1011 and a first two temperature sensor 1012, and the second temperature sensor 102 comprises a second one temperature sensor 1021 and a second two temperature sensor 1022. The second one temperature sensor 1021 is fixedly arranged on the side wall 123 corresponding to the first baking space, the first one temperature sensor 1011 is movably arranged on the first accommodating portion 131 provided on the side wall 123 corresponding to the second baking space, the first two temperature sensor 1012 is movably arranged on the second accommodating portion 132 provided on the side wall 123 corresponding to the third baking space, and the second two temperature sensor 1022 is fixedly arranged on the side wall 123 corresponding to the fourth baking space.

[0061] In another exemplary embodiment, the side wall comprises a left side wall, a rear side wall and a right side wall connected in sequence, and the left side wall and the right side wall are oppositely arranged.
[0062] The first heating member is arranged on the left side wall, and the second heating member is arranged on the right side wall. The cooking accessory is a grill. The two ends of the cooking accessory are connected to the top wall and the bottom wall respectively, so that the cooking accessory 40 is arranged in the vertical direction, and food can be hung on the cooking accessory 40. When at least one cooking accessory 40 is placed in the baking cavity 11, the baking cavity 11 is separated into at least two baking spaces 111 in the horizontal direction. For example, if the oven is provided with one cooking accessory 40, two baking spaces 111 are separated, and the first baking space 111 is defined between the cooking accessory 40 and the left side wall, and the second baking space 111 is defined between the cooking accessory 40 and the right side wall. If the oven is provided with two cooking accessories 40, three baking spaces 111 are separated, and the first baking space 111 is defined between the cooking accessory 40 and the left side wall 123, the second baking space 111 is defined between the two cooking accessories 40, and the third baking space 111 is defined between the cooking accessory 40 and the right side wall. Similarly, if the oven is provided with three cooking accessories 40, the baking cavity 11 is separated into four baking spaces 111. In the embodiment, at least one first temperature sensor 101 is arranged in each baking space 111. The side wall 123 is provided with a receiving portion 13 corresponding to the first temperature sensor 101, so that the first temperature sensor 101 can be received in the receiving portion 13, so as to avoid interference between the cooking accessory 40 and the first temperature sensor 101.
[0063] In some embodiments of the present application, the oven further comprises a driving mechanism, a detection unit and a control device.
[0064] Specifically, the driving mechanism has a power output end, and the power output end of the driving mechanism is connected to the first temperature sensor 101, so as to drive the first temperature sensor 101 to move between the first position and the second position. The detection unit is used for detecting the position of the cooking accessory 40. The control device is electrically connected to the detection unit and the driving mechanism. The detection unit transmits the position information of the cooking accessory 40 detected to the control device. The control device can control the position of the first temperature sensor 101 according to the position information of the cooking accessory 40, so as to avoid interference between the cooking accessory 40 and the first temperature sensor 101.
[0065] Moreover, the control device is electrically connected to the first heating member 20, the second heating member 30 and the first temperature sensor 101 respectively, so that the first temperature sensor 101 transmits the acquired temperature information to the control device. The control device controls the operation of the first heating member 20 and the second heating member 30 according to the temperature data measured by the first temperature sensor 101 and the instruction data, so as to realize accurate temperature control of the oven.
[0066] In some embodiments of the present application, the accommodating portion 13 is a groove (not shown in the figure) extending along the inner wall, the groove is long strip-shaped, and one end of the first temperature sensor 101 is rotatably arranged in the groove, so that the other end of the first temperature sensor 101 can rotate relative to the groove. In the first position state, the first temperature sensor 101 and the groove form an approximately 90-degree angle, so that part of the body of the first temperature sensor 101 extends into the baking cavity 11. In the second position state, the first temperature sensor 101 is rotated by 90 degrees relative to the groove, so that the first temperature sensor 101 is completely accommodated inside the groove.
[0067] In the present embodiment, the first temperature sensor 101 moves between the first position and the second position in a rotating manner relative to the accommodating portion 13. The driving mechanism includes an electrode and a transmission member, and the rotating shaft of the motor is in transmission connection with one end of the first temperature sensor 101 through the transmission member, so as to output a rotating power to the first temperature sensor 101, thereby driving the first temperature sensor 101 to rotate relative to the accommodating portion 13.
[0068] Specifically, the motor can be a stepper motor to accurately control the rotation angle of the first temperature sensor 101. The transmission member can be a gear mechanism or a connecting rod mechanism, which is not limited here.
[0069] Please refer again to Figure 1 and Figure 2 In some embodiments of the present application, the accommodating portion 13 is a counterbore or a through hole extending in a direction perpendicular to the inner wall, and one end of the first temperature sensor 101 is slidably arranged in the accommodating portion 13, so that the first temperature sensor 101 moves between the first position and the second position in a telescopic manner in the accommodating portion 13.
[0070] Specifically, the power output end of the driving mechanism is a linear motion member.
[0071] For example, the driving mechanism is a crank slider mechanism, the slider in the crank slider mechanism is connected with the first temperature sensor 101, and the slider is slidably arranged in the accommodating portion 13, so that the first temperature sensor 101 moves between the first position and the second position through the reciprocating sliding of the slider.
[0072] For another example, the driving mechanism is a gear and rack mechanism, the rack is a straight rack and is slidably arranged in the accommodating portion 13, one end of the rack is connected with the first temperature sensor 101, and the first temperature sensor 101 moves between the first position and the second position through the reciprocating movement of the rack.
[0073] Alternatively, the driving mechanism can be a ball screw mechanism, a telescopic fence mechanism or a cam mechanism, which can also realize the movement of the first temperature sensor 101 between the first position and the second position.
[0074] In combination withFigures 1 to 6 As shown, in some embodiments of the present application, a control method of an oven is provided, which is implemented according to the oven of any of the above embodiments, such as Figure 5 As shown, the control method comprises the following steps:
[0075] Obtaining position information of the cooking accessory 40;
[0076] Controlling the first temperature sensor 101 to switch to the first position or the second position according to the position information.
[0077] According to the control method provided by the present application, according to the position information of the cooking accessory 40, it is determined whether the first temperature sensor 101 needs to be stored in the accommodation portion 13, and according to the position information of the cooking accessory 40, the position of the first temperature sensor 101 is changed, that is, interference with the first temperature sensor 101 when placing or taking the cooking accessory 40 can be avoided, and more accurate temperature data of the interior of the baking cavity 11 during cooking can be obtained, so that the temperature control of the oven is more accurate.
[0078] Please refer to Figure 5 and Figure 6 As shown, in some embodiments of the present application, the following steps are further included:
[0079] Obtaining position information of the cooking accessory 40 comprises: determining whether the cooking accessory 40 is placed in the baking cavity 11; if the cooking accessory is not placed in the baking cavity, it is determined that the first temperature sensor 101 is not needed. According to the fact that the cooking accessory 40 is not placed in the baking cavity 11, the first temperature sensor 101 is controlled to switch to the second position, and the first temperature sensor 101 is stored in the accommodation portion 13, so as to avoid interference between the first temperature sensor 101 and the cooking accessory 40 when the cooking accessory 40 is placed.
[0080] In some embodiments of the present application, after determining whether the cooking accessory 40 is placed in the baking cavity 11, the following steps are further included:
[0081] According to the fact that the cooking accessory 40 is placed in the baking cavity 11, the position of each cooking accessory 40 in the baking cavity 11 is obtained;
[0082] According to the position of each cooking accessory 40, the cooking accessory 40 closest to the second heating element 30 located on the top wall 122 of the baking cavity 11 is determined as the first target cooking accessory 40, that is, the cooking accessory 40 closest to the second heating element 30 is determined;
[0083] According to the first target cooking accessory 40, the first temperature sensor 101 adjacent to the first target cooking accessory 40 and located between the first target cooking accessory 40 and the second heating member 30 is determined as the main temperature sensor, the main temperature sensor is determined as the first temperature sensor 101 located between the first target cooking accessory 40 and the second heating member 30 and closest to the first target cooking accessory 40, and the main temperature sensor can quickly and accurately reflect the temperature of the area on the side of the first target cooking accessory 40 facing the second heating member 30;
[0084] The main temperature sensor is controlled to switch to the first position, so that the main temperature sensor extends into the baking cavity 11, so that the furnace core temperature can be quickly and accurately detected by the main temperature sensor.
[0085] It should be noted that, since the food needs to be placed on the cooking accessory 40, the main temperature sensor is the first temperature sensor 101 closest to the food placed on the cooking accessory 40, and therefore the temperature data detected by the main temperature sensor is closest to the temperature data of the area where the food is located. Therefore, it is more accurate to use the data detected by the main temperature sensor as the reference data of the furnace core temperature.
[0086] In some embodiments of the present application, the following steps are further included:
[0087] Before the main temperature sensor is controlled to move to the first position, the following steps are further included:
[0088] An independent temperature control mode instruction is obtained.
[0089] According to the independent temperature control mode instruction, at least one first temperature sensor 101 other than the main temperature sensor is controlled to switch to the second position.
[0090] Specifically, the independent temperature control mode is to control the first heating member 20 and the second heating member 30 to operate at the same power at the same time. In the independent temperature control mode, only the main temperature sensor participates in temperature control, and the remaining first temperature sensors 101 do not participate in control, and therefore the remaining first temperature sensors 101 other than the main temperature sensor can be accommodated in the accommodation portion 13 to avoid interference with the cooking accessory 40. In the independent temperature control mode, the temperature of the main temperature sensor and the furnace core temperature have a one-to-one mapping relationship, and after the target temperature of the furnace core is determined, the temperature measured by the main temperature sensor is used as a reference to adjust the furnace core temperature to achieve the purpose of accurate temperature control. For example, if the value of the main temperature sensor is 220℃, the corresponding furnace core temperature is 218℃. If the target temperature of the furnace core is 218℃, when the value of the main temperature sensor is less than 220℃, the first heating member 20 and the second heating member 30 are controlled to increase the operating power, so that the furnace core temperature rises until the value of the main temperature sensor is 220℃, and the furnace core temperature is adjusted to 218℃.
[0091] In some embodiments of the present application, the following steps are further included:
[0092] The controlling further includes:
[0093] The independent temperature control mode instruction is an instruction for separately controlling the first heating element 20 and the second heating element 30, so that the first heating element 20 and the second heating element 30 are heated to different temperatures, respectively.
[0094] According to the independent temperature control mode instruction and the positions of the cooking accessories 40, the cooking accessory 40 closest to the first heating element 20 located at the bottom wall 121 of the baking cavity 11 is determined as the second target cooking accessory 40, i.e., the cooking accessory 40 closest to the first heating element 20.
[0095] According to the second target cooking accessory 40, the first temperature sensor 101 adjacent to the second target cooking accessory 40 and located between the second target cooking accessory 40 and the first heating element 20 is determined as a secondary temperature sensor, i.e., the first temperature sensor 101 located between the second target cooking accessory 40 and the first heating element 20 and closest to the second target cooking accessory 40, which can quickly and accurately reflect the temperature of the area on the side of the second target cooking accessory 40 facing the first heating element 20.
[0096] The secondary temperature sensor is controlled to switch to the first position, so that the secondary temperature sensor extends into the baking cavity 11, so as to reflect the temperature of the area heated by the first heating element 20 through the temperature measured by the secondary temperature sensor.
[0097] It should be noted that in the independent temperature control mode, the main temperature sensor reflects the temperature of the area heated by the second heating element 30, and the secondary temperature sensor reflects the temperature of the area heated by the first heating element 20. Therefore, the second heating element 30 can be controlled based on the temperature value measured by the main temperature sensor, and the first heating element 20 can be controlled based on the temperature value measured by the secondary temperature sensor, so as to achieve separate control of the first heating element 20 and the second heating element 30.
[0098] In some embodiments of the present application, the following steps are further included:
[0099] It is determined whether each first temperature sensor 101 is a main temperature sensor or a secondary temperature sensor. If the first temperature sensor 101 is neither marked as a main sensor nor marked as a secondary sensor, it means that the first temperature sensor 101 does not participate in the temperature control of the oven.
[0100] If not, the first temperature sensor 101 is controlled to switch to the second position, so that the first temperature sensor 101 not participating in the temperature control of the oven is stored in the accommodation portion.
[0101] In some embodiments of the present application, the following steps are further included:
[0102] obtaining a cooking end instruction or a pause instruction;
[0103] According to the cooking end instruction or the pause instruction, the at least one first temperature sensor 101 is controlled to switch to the second position to prevent interference with the first temperature sensor 101 when the food is placed on the cooking accessory 40 or taken out.
[0104] In combination Figure 2 - and Figure 6 As shown, according to one specific embodiment of the present application, a control method of an oven is proposed,
[0105] The oven is sequentially and spacedly provided with a first mounting portion 51, a second mounting portion 52 and a third mounting portion 53 from top to bottom, and the first mounting portion 51, the second mounting portion 52 and the third mounting portion 53 are all used for placing the cooking accessory 40.
[0106] The control method includes the following steps:
[0107] Firstly, it is judged whether the cooking accessory 40 is placed in the baking cavity 11. If there is no baking tray, the first temperature sensor 1011 and the second temperature sensor 1012 are respectively accommodated in the first accommodating portion 131 and the second accommodating portion 132;
[0108] If there is a baking tray, firstly, it is judged the placement position of the uppermost cooking accessory 40 among the placed cooking accessories 40. If the uppermost cooking accessory 40 is placed at the position of the first mounting portion 51, the main temperature sensor is determined as the second temperature sensor 1021. If the uppermost cooking accessory 40 is placed at the position of the second mounting portion 52, the main temperature sensor is determined as the first temperature sensor 1011. If the uppermost cooking accessory 40 is placed at the position of the third mounting portion 53, the main temperature sensor is determined as the second temperature sensor 1012.
[0109] It is judged whether the temperature control instruction is an independent temperature control mode. If the temperature control instruction is a non-independent temperature control mode, the temperature sensor determined as the main temperature sensor is kept in the state of extending into the baking cavity 11. For example, if the second temperature sensor 1021 is the main temperature sensor, the first temperature sensor 1011 and the second temperature sensor 1012 remain unchanged in the second position. If the first temperature sensor 1011 is the main temperature sensor, the first temperature sensor 1011 is controlled to move to the first position, and the second temperature sensor 1012 remains unchanged in the second position. If the second temperature sensor 1012 is the main temperature sensor, the second temperature sensor 1012 is controlled to move to the first position, and the first temperature sensor 1011 remains unchanged in the second position.
[0110] When the temperature control is in the independent temperature control mode, the placement position of the cooking accessory 40 placed at the lowermost layer is determined. If the placed lowermost cooking accessory 40 is at the position of the first mounting portion 51, the first temperature sensor 1011 is determined as the secondary temperature sensor. If the placed lowermost cooking accessory 40 is at the position of the second mounting portion 52, the second temperature sensor 1012 is determined as the secondary temperature sensor. If the placed lowermost cooking accessory 40 is at the position of the third mounting portion 53, the second temperature sensor 1022 is determined as the secondary temperature sensor. At the same time, the primary temperature sensor and the secondary temperature sensor are controlled to move to the first position to keep the state of extending into the baking cavity 11. If the first temperature sensor 1011 or the second temperature sensor 1012 is neither the primary temperature sensor nor the secondary temperature sensor, it is stored in the receiving portion 13.
[0111] Specifically, when the non-independent temperature control mode, the primary temperature sensor is as the sensor of the reactor core temperature. In the algorithm, the temperature of the primary temperature sensor is in one-to-one mapping relationship with the core temperature, and the PID algorithm is used to quickly and accurately reach the target value. In the independent temperature control mode, the first heating member and the second heating member are controlled separately. The second heating member is controlled by the feedback temperature of the primary temperature sensor, and the first heating member is controlled by the feedback temperature of the secondary temperature sensor.
[0112] For example, in a specific embodiment, when the user cooks small cakes, the first temperature sensor or the second temperature sensor is in the second position before cooking starts. The small cakes are placed on the baking tray, and the baking tray with the small cakes is placed in the oven. The independent temperature control mode is set to 220℃ for the second heating member and 160℃ for the first heating member. The cooking starts, the first temperature sensor and the second temperature sensor are in the first position, the cooking ends, and the first temperature sensor and the second temperature sensor return to the second position.
[0113] The above description is only a preferred embodiment of the present application, but the protection scope of the present application is not limited thereto. Any changes or replacements within the technical range disclosed by the present application can be easily thought by those skilled in the art, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
