As shown in fig. 1-3, the conventional oven 100 includes a case 110 and an inner container 120 disposed inside the case 110.
The box 110 is generally a rectangular parallelepiped structure, and a box-shaped structure with an opening is formed by surrounding five surfaces to protect the internal structure, the inner container 120 is located inside the box 110, the inner container 120 is formed with a semi-closed cavity inside the box 110, and has a box-shaped structure corresponding to the box 110, and correspondingly, the opening of the inner container 120 corresponds to the opening of the box 110.
Generally, the inner container 120 is fixed in the cabinet 110 by a fixing member, and since the oven 100 performs high-temperature cooking of food through the cooking space inside the inner container 120, in order to avoid heat loss, the opening of the inner container 120, i.e., the open end of the cavity, is closed by the oven door 130 hinged to the cabinet 110.
The toaster door 130 includes a door body and a door frame.
The door frame is fixedly connected between the inner container 120 and the box body 110 to form a part of closed surface at the opening of the box body 110, and the door frame is arranged around the opening of the inner container 120 to fixedly connect the opening of the inner container 120 with the opening of the box body 110, so that the fixed installation between the box body 110 and the inner container 120 is realized.
The door is generally pivotally connected to a door frame for opening or closing the opening of the inner container 120.
The outer side wall of the inner container 120 is covered with a heating device, which is usually configured as a heating pipe for heating the heating space in the inner container 120.
The heating device is electrically connected with a control device.
Generally, the top, the side and the bottom of the inner container 120 are respectively provided with a top heating pipe, a side heating pipe and a bottom heating pipe for providing heat inside the inner container 120, and meanwhile, one side of the inner container 120 departing from the oven door 130 is also provided with a heating pipe, and the side is also provided with a circulating fan which is used for sending heat generated by the heating pipe into the inner container 120, so that air in the inner container 120 flows and circulates, and the heating is uniform.
The inner container 120 forms heating spaces of different levels in the box body 110 for accommodating the baking trays 140, and the space positions of the inner container 120 of different levels are also different.
The heating spaces of different levels are respectively provided with a hanging rack 121, and the hanging rack 121 is used for stably placing the baking tray 140.
The baking tray 140 is used for carrying food to be baked, and the baking tray 140 is installed on the placing structures of different layers, so that the relative distance between the food and the heating pipe can be adjusted.
Because the distances from the heating pipes are different, the heating effects of different levels are also different, so that different levels can be respectively used for heating different food materials, for example, the food materials such as bread and the like which need to be baked can be placed at the middle layer position of the inner container 120, the distance from the heating pipes is far, the bread is not easy to be burnt, raw food of meat is not easy to be baked, and the raw food of meat can be preferentially placed at the upper level or the lower level and the positions of the heating pipes are near.
It should be noted that, since the conventional oven 100 uses a smart program with high power heating, food needs to be placed at a designated level for the best cooking effect, the temperature measuring system 200 of the conventional oven 100 cannot detect whether the food is placed at a proper level of the rack 121.
In addition, since the control of the baking effect of the conventional oven 100 is mainly set by the baking mode, the baking time, and the baking temperature, the temperature sensor 210 needs to be installed inside the inner container 120 in order to monitor and reasonably control the heating temperature of the inner container 120 in real time.
The temperature sensor 210 of the general oven 100 detects the temperature in the oven 100 by using a probe-type temperature probe, the probe-type temperature probe extends from the inner wall of the oven body 110 to the oven body 110 by a section, but the distance from the baked object to the heating pipe is far, the temperature measured by the method is not accurate, and the problem of temperature detection lag exists, the temperature state of the baked food cannot be accurately judged, the result of repeated baking or excessive baking is caused, and the temperature rise rate of the baking tray 140 is higher than the cavity ring temperature of the oven 100 due to the material of the metal when a high-power auxiliary heating pipe is used, the temperature of the baking tray 140 cannot be detected, and the temperature of the baking tray 140 is higher than the preset temperature, so that the bottom of the food is burnt.
Based on the above-mentioned problem that the temperature probe in the prior art cannot detect the temperature of the bakeware 140 and the problem that the conventional oven 100 cannot detect whether the food is placed at the proper level of the inner container 120, in some embodiments of the present application, as shown in fig. 4-6, the oven 100 further includes a temperature measuring system 200.
The temperature measuring system 200 is located at the back of the inner container 120 and electrically connected to the control device, and the temperature measuring system 200 is respectively disposed in a plurality corresponding to different levels of the inner container 120.
In the operation process of the oven 100, the temperature measurement system 200 is started, the user puts the baking tray 140 into the inner container 120 at the designated level, the baking tray 140 contacts the temperature measurement system 200, and the temperature measurement system 200 is used for judging whether the baking tray 140 is at the first position and measuring the temperature of the baking space of the inner container 120 at the current level corresponding to the baking tray 140 and the baking tray 140.
It should be noted that the temperature measurement system 200 can ensure that the temperature measurement point is closely attached to the baking tray 140, and real-time detection of the temperature of the baking tray 140 is realized, so that the situation that the bottom of the food is burnt due to the temperature of the baking tray 140 being higher than a preset temperature is avoided.
Meanwhile, the temperature measuring systems 200 respectively correspond to different levels in the inner container 120, and respectively measure the temperature of the spaces in the different levels and the baking trays 140 arranged in the levels, when a high-power heating intelligent program is used, food can be cooked to achieve the best cooking effect only by placing the food at the appointed level, and the scheme can detect whether the food is placed at the proper level through the temperature measuring systems 200.
For example, when the toaster 100 toasts meat, a user may first input a "toast meat" signal on the control device, since the fresh food such as meat is not easy to be baked, the control device can prompt the user that the baking level is close to the heating pipe after receiving the signal, i.e., near the side wall of the inner container 120, but if the user fails to operate the inner container 120, the tray 140 for holding the meat is placed at the middle level of the inner container 120, since the bakeware 140 contacts the temperature measurement system 200 of the current level, the control device receives the signal transmitted by the temperature measurement system 200 of the wrong level, the user can be further prompted to prompt the user that the placement level of the baking tray 140 in the inner container 120 needs to be changed, the whole process is more intelligent, the double prompt prompts the reasonable arrangement of the placing position of the baking tray 140, so that the problem that the user places the baking tray 140 at the wrong position to cause the baking of the food is not done or the food is scorched is solved.
Based on the above description, in some embodiments of the present application, as shown in fig. 4-6, a temperature measurement system 200 includes a temperature sensor 210, a temperature sensor extension 220, and a temperature sensor magnetic induction switch 230.

It should be noted that the baking tray 140 can be placed inside the inner container 120 of the oven 100, the temperature measuring system 200 is located at the back of the inner container 120 of the oven 100, the temperature sensor 210 for detecting the temperature of the baking tray 140 is located at the head of the temperature measuring system 200, the temperature sensor 210 is connected with the temperature sensor telescopic part 220, so that the temperature sensor can be stretched back and forth, the front end of the temperature sensor 210 is always located inside the inner container 120 of the oven 100 during the use process, and the temperature sensor magnetic induction switch 230 is located at the tail of the temperature sensor 210.
When the oven is used, when the baking tray 140 is placed in the inner container 120 of the oven 100, the baking tray 140 is placed at a designated level position and pushed inwards, the surface of the baking tray 140 can contact the temperature sensor 210, the temperature sensor telescopic piece 220 can ensure that the head of the baking tray 140 is tightly attached to the head of the temperature sensor 210, meanwhile, when the elastic structure of the temperature sensor 210 is compressed, the temperature sensor magnetic induction switch 230 can sense the displacement of the temperature sensor, namely, the baking tray 140 is placed, the position for placing the baking tray 140 is detected, and the problem that partial food is not in a heating area due to the fact that the baking tray 140 is not placed in place and cannot reach an even cooking result is avoided.
Based on the above embodiment, the temperature sensor extension piece 220 can sense the placing position of the baking tray 140 by extension and retraction.
When the temperature sensor extension piece 220 is compressed, it indicates that the baking tray 140 is placed at the correct position.
When the baking tray 140 is placed into the inner container 120 at a designated level, the surface of the baking tray 140 can contact the temperature sensor 210 corresponding to the current level, and meanwhile, when the baking tray 140 is pushed into the inner container 120 to a designated position, the temperature sensor expansion piece 220 is compressed, and at this time, the temperature measurement system 200 is turned on and controls the heating device to be turned on through the control device, so that the oven 100 performs heating operation.
In some embodiments of the present application, as shown in fig. 4-6, the temperature measuring system 200 further includes a temperature sensor fixing member 240, and the temperature sensor fixing member 240 is used to fixedly mount the temperature measuring system 200 on the back of the liner 120.
During the actual operation of the oven 100 according to the above embodiment, the oven 100 is in the following two operation states: a preheating state of the baking tray 140 and a food heating state.
(1) When the oven 100 is in the grill pan 140 pre-heated state, as shown in fig. 5-6, the temperature measurement system 200 is configured to:
