In one aspect, referring to fig. 1 and 2, fig. 1 is a schematic structural diagram of an embodiment of a temperature probe according to the present application, and fig. 2 is a schematic structural diagram of the temperature probe shown in fig. 1. The temperature probe 100 may include a housing 10, a first temperature sensor 20 and a second temperature sensor 30 disposed within the housing 10, and a rechargeable power source 40, a circuit board 50, and a wireless communication assembly 60 disposed within the housing 10. The first temperature sensor 20 and the second temperature sensor 30 may be disposed at opposite ends of the housing 10, respectively, and the rechargeable power source 40, the circuit board 50 and the wireless communication module 60 may be disposed between the first temperature sensor 20 and the second temperature sensor 30. The temperature probe 100 of the present embodiment can be used in combination with an oven, and the temperature probe 100 can be inserted into food to be cooked when in use.
Specifically, the housing 10 may include a first tube 11, a second tube 12, and a handle 13 connected in sequence. In the present embodiment, the first tube 11 and the second tube 12 may be made of metal having good electrical and thermal conductivity, for example, the first tube 11 and the second tube 12 may be made of stainless steel. The first tube 11 is configured to be inserted into food to be cooked, and the first tube 11 and the second tube 12 may be mechanically connected by a high temperature resistant insulating material 15, for example, the first tube 11 and the second tube 12 may be mechanically connected by a high temperature resistant insulating plastic. The handle 13 may be made of a high temperature resistant insulating material, such as the handle 13 may be made of PEEK (Polyetheretherketone) plastic. The handle 13 and the second pipe body 12 can be integrally injection molded. In addition, the end of the handle 13 remote from the second tubular body 12 may also be provided with a metallic end cap 14.
In some embodiments, the insulating material 15 may not be disposed between the first tube body 11 and the second tube body 12, for example, the first tube body 11 and the second tube body 12 may be integrally formed stainless steel tubes, which is not limited in the present application, and may be selected by those skilled in the art according to practical needs. In some embodiments, the handle 13 may also be directly sleeved on the second tube body 12, which is not limited in the present application, and those skilled in the art may select according to actual needs.
The first temperature sensor 20 and the second temperature sensor 30 are respectively disposed at opposite ends of the temperature probe 100. Specifically, the first temperature sensor 20 is disposed at an end of the first tube 11 away from the second tube 12, and the second temperature sensor is disposed at an end of the handle 13 away from the second tube 12. When the temperature probe 100 is inserted into the food to be cooked, the first temperature sensor 20 is located inside the food to be cooked, and can be used to detect the temperature inside the food to be cooked to feed back the maturity of the food; the second temperature sensor 30 is exposed to the outside of the food to be cooked, and can be used to detect the temperature in the oven cavity, and thus the heating power of the oven can be controlled according to the temperature detected by the second temperature sensor 30.
Further, as shown in fig. 3, fig. 3 is another schematic structural view of the temperature probe shown in fig. 1, and the outer surfaces of the first tube 11 and the second tube 12 may be provided with graduation marks 111 to determine a specific depth of insertion of the temperature probe 100 into the food to be cooked, thereby facilitating a user to determine whether the temperature probe 100 is inserted into a geometric center region of the food to be cooked.
Specifically, the graduation marks 111 may extend from the first temperature sensor 20 toward the direction in which the handle 13 is located. The user can comprehensively determine whether the temperature probe 100 is inserted into the geometric center region of the food to be cooked in combination with the specific depth of the temperature probe 100 inserted into the interior of the food and the overall size of the food to be cooked. If the temperature probe 100 is inserted into the geometric center region of the food to be cooked, the maturity of the food to be cooked can be accurately reflected if the temperature detected by the first temperature sensor 20 is the temperature of the geometric center region of the food to be cooked. If the temperature probe 100 is not inserted into the geometric center area of the food to be cooked, the temperature detected by the first temperature sensor 20 is not the temperature of the geometric center area of the food to be cooked, and the maturity of the food to be cooked cannot be accurately reflected.
For example, the graduation marks 111 may be printed on the first tube 11 and the second tube 12 by a silk screen process, which is not limited in the present application, and may be selected by those skilled in the art according to actual needs. The minimum graduation unit of the graduation mark 111 may be cm, mm, or any other length unit, which is not limited by the present application, and may be selected by those skilled in the art according to actual needs.
In this embodiment, the first temperature sensor 20 and the second temperature sensor 30 may be NTC (Negative Temperature Coefficient Sensor) temperature sensors, however, the first temperature sensor 20 and the second temperature sensor 30 may be other types of temperature sensors, which are not limited in this respect, and may be selected by those skilled in the art according to practical requirements.
In some embodiments, the temperature probe 100 may also include only the first temperature sensor 20, and the second temperature sensor 30 is not provided, which is not limited by the present application, and one skilled in the art may select according to actual needs.
The rechargeable power source 40 may be disposed within the first tube 11. Specifically, the temperature probe 100 in the present embodiment is a wireless probe, that is, the temperature probe 100 is not connected to the oven through a wire, and the rechargeable power source 40 is used to provide electric energy to the temperature probe 100. When the rechargeable power source 40 needs to be charged, the first tube 11 can be used as the negative electrode of the rechargeable power source 40, and the metal end cover 14 can be used as the positive electrode of the rechargeable power source 40.
For example, the rechargeable power source 40 may be a super capacitor, and of course, the present application is not limited to the specific type of the rechargeable power source 40, and those skilled in the art may choose according to actual requirements. In some embodiments, the power source in the temperature probe 100 may also be a non-rechargeable power source, for example, the temperature probe 100 may also use a disposable battery as the power source. In some embodiments, the temperature probe 100 may also be a wired probe, and the connection to the oven is made directly via a wired line, in which case there is no need to provide a power supply within the temperature probe 100.
The circuit board 50 may be disposed in the first tube 11, on the one hand, the circuit board 50 is electrically connected to the rechargeable power source 40, and the rechargeable power source 40 provides electric energy for the circuit board 50; on the other hand, the circuit board 50 is also connected to the first temperature sensor 20 and the second temperature sensor 30 to control the first temperature sensor 20 and the second temperature sensor 30.
Since the temperature in the oven cavity is relatively high, the rechargeable power source 40 and the circuit board 50 are poorly resistant to high temperatures, and the temperature probe 100 should be completely inserted into the food to be cooked when in use, so as to protect the rechargeable power source 40 and the circuit board 50 disposed in the first tube 11. If the first tube 11 is not fully inserted into the food to be cooked, it is possible that the temperature probe 100 is damaged at high temperature during use.
To protect the temperature probe 100, on the one hand, a sign line 151 may be provided on the housing 10 to prompt the user that the depth of insertion into the food to be cooked should reach at least the sign line 151 to protect the electronic components provided in the first tube 11. In this embodiment, the insulating material 15 between the first tube body 11 and the second tube body 12 may be provided with a marking line 151, and the marking line 151 may be any one or a combination of several of a color marking, a groove and a protrusion, which is not limited in the present application, and may be selected by those skilled in the art according to actual needs.
Further, a detection circuit (not shown in the drawings) for detecting whether the first tube 11 is completely inserted into the food to be cooked may be further provided on the circuit board 50. In this embodiment, as shown in fig. 2, the first tube 11 and the second tube 12 are mechanically connected by an insulating material 15, and in addition, the first tube 11 and the second tube 12 are electrically connected by a resistor 112 with larger resistance; when the first pipe body 11 is completely inserted into the food to be cooked, the first electric signal can be detected by the detection circuit through the short circuit between the first pipe body 11 and the second pipe body 12 due to moisture in the food to be cooked; when the first tube 11 is not fully inserted into the food to be cooked, the first tube 11 and the second tube 12 are electrically connected through the resistor 112, and the detection circuit detects a second electrical signal, wherein the second electrical signal is different from the first electrical signal. Therefore, the detection circuit can judge whether the first tube 11 is completely inserted into the food to be cooked according to the detected electric signals.
When the detection circuit detects the first electrical signal, the temperature probe 100 may be controlled to operate normally. When the detection circuit detects the second electrical signal, the wireless communication assembly 60 can be controlled to send an alarm signal to other devices, for example, when the detection circuit detects the second electrical signal, the wireless communication assembly 60 can be controlled to send an alarm signal to the oven so that the oven pauses the cooking process; for another example, when the detection circuit detects the second electrical signal, the temperature probe 100 may be controlled to send an alarm signal to a smart terminal, such as a smart phone, a tablet, a smart wearable device, etc. used by the user, so as to prompt the user that the temperature probe 100 is not used correctly.
According to the embodiment, the detection circuit is arranged in the temperature probe 100, and the detection circuit detects different electric signals when the first pipe body 11 is completely inserted into food to be cooked and when the first pipe body 11 is not completely inserted into the food to be cooked, so that the erroneous operation that the temperature probe 100 is not inserted in place is identified, further, a warning signal can be sent out, and damage caused by the fact that the temperature probe 100 is not inserted in place is avoided.
In addition, the temperature probe provided in this embodiment is also beneficial to avoid the situation that the user forgets to insert the temperature probe 100 into the food to be cooked. Specifically, if the user forgets to insert the temperature probe 100 into the food to be cooked, the detection circuit will detect the second electrical signal, and at this time, an alarm signal will be sent to the oven or the intelligent terminal used by the user through the wireless communication component 60.
In some embodiments, the first tube 11 and the second tube 12 are mechanically connected by an insulating material 15, and the first tube 11 and the second tube 12 are electrically connected by a diode; when the first pipe body 11 is completely inserted into the food to be cooked, the first electric signal can be detected by the detection circuit through the short circuit between the first pipe body 11 and the second pipe body 12 due to moisture in the food to be cooked; when the first tube 11 is not fully inserted into the food to be cooked, the first tube 11 and the second tube 12 are electrically connected through the diode, and the detection circuit detects a second electrical signal, wherein the second electrical signal is different from the first electrical signal. Therefore, the detection circuit can judge whether the first tube 11 is completely inserted into the food to be cooked according to the detected electric signals.
In some embodiments, as shown in fig. 4, fig. 4 is a schematic structural diagram of another embodiment of the temperature probe of the present application, where the first tube 11 and the second tube 12 may be connected only by the insulating material 15, and there is no electrical connection relationship; when the first pipe body 11 is completely inserted into the food to be cooked, the first electric signal can be detected by the detection circuit through the short circuit between the first pipe body 11 and the second pipe body 12 due to moisture in the food to be cooked; when the first tube 11 is not fully inserted into the food to be cooked, the first tube 11 and the second tube 12 are disconnected, no electrical connection exists, and the detection circuit detects the second electrical signal, at this time, the second electrical signal is zero and is different from the first electrical signal. Therefore, the detection circuit can judge whether the first tube 11 is completely inserted into the food to be cooked according to the detected electric signals.
The wireless communication assembly 60 is disposed in the housing 10, and the temperature probe 100 can transmit the temperature data detected by the first temperature sensor 20 and the second temperature sensor 30 to the oven through the wireless communication assembly 60, so that the oven can control the cooking process according to the temperature data detected by the first temperature sensor 20 and the second temperature sensor 30. In some embodiments, the wireless communication component 60 may also send the temperature data detected by the first temperature sensor 20 and the second temperature sensor 30 to a smart terminal used by the user, such as a smart phone, a tablet, a smart wearable device, etc., so that the user can view the cooking condition of the food to be cooked in real time.
As shown in fig. 2, in the present embodiment, one end of the wireless communication assembly 60 is electrically connected to the circuit board 50, and the other end extends to the metal end cover 14, and performs electrical signal transmission with other external electronic devices through the metal end cover 14. For example, the wireless communication module 60 may be a bluetooth antenna, however, the application is not limited thereto, and the wireless communication module 60 may be any other type of antenna, and those skilled in the art may select according to practical requirements.
In some embodiments, the temperature probe 100 may also be a wired probe, and the temperature data detected by the first temperature sensor 20 and the second temperature sensor 30 are directly sent to the oven through wired lines, and of course, when the detection circuit detects that the temperature probe is not inserted in place, an alarm signal may also be sent to the oven through wired lines, so that the oven pauses the cooking process, which is not limited by the present application, and those skilled in the art may select according to actual needs.
In another aspect, the present application provides an oven assembly 300, as shown in fig. 5, fig. 5 is a schematic structural diagram of an embodiment of the oven assembly of the present application.

In this embodiment, the oven 200 may include a heating assembly and a control assembly, and the temperature probe 100 may include a wireless communication assembly that transmits a temperature signal detected by the temperature probe 100 to the control assembly, so that the control assembly controls the heating assembly according to the temperature signal detected by the temperature probe 100. For a detailed description of the temperature control method embodiment of the oven, please refer to the following, how the control assembly controls the heating assembly based on the temperature signal detected by the temperature probe 100.

The inventor has long studied and found that temperature control can be achieved by providing temperature sensors on the inner walls of the oven cavity, such as in the corners of the oven, and then establishing a mapping relationship between the corner temperatures measured by the temperature sensors and the temperature of the oven core through a large number of tests, and curing the mapping relationship into a temperature control program.
However, in the actual use process of the oven, the variety of foods to be cooked which are put into the oven have large size differences. When foods to be cooked with larger size are put in, the temperature field distribution in the oven cavity of the oven can be changed, so that when the oven is executed according to a preset program, the actually controlled temperature of the oven core deviates from the set temperature, and finally, the cooking effect is poor.
In this embodiment, the first temperature data may be determined by the temperature in the oven cavity detected by the temperature probe and the temperature in the oven cavity detected by the second temperature sensor, which is favorable for eliminating the influence of food to be cooked on the temperature field distribution in the oven cavity, and more accurately reflecting the real temperature in the oven cavity, thereby being favorable for improving the temperature control precision of the oven and the cooking effect.
In some embodiments, the first temperature data may also be determined only by the temperature in the oven cavity detected by the temperature probe, which is not limited by the present application, and one skilled in the art may freely select according to the accuracy requirement of the temperature control of the oven for the food to be cooked.
S103: the first temperature data is compared with a first preset temperature.
With respect to the specific value of the first preset temperature, the present application is not limited, and one skilled in the art may select according to actual needs. Specifically, if the first temperature data is greater than or equal to the first preset temperature, it indicates that the actual temperature in the oven cavity is too high, and the heating needs to be stopped or the heating power needs to be reduced, so that the actual temperature in the oven cavity is reduced. If the first temperature data is smaller than the first preset temperature, the actual temperature in the furnace chamber is insufficient, and the heating needs to be continued or the heating power needs to be increased, so that the actual temperature in the furnace chamber is increased.
S104: and controlling the heating power of the oven according to the comparison result.
Specifically, if the first temperature data is greater than or equal to the first preset temperature, the control component controls the heating component to stop heating or reduce heating power, so that the actual temperature in the furnace chamber is reduced. If the first temperature data is smaller than the first preset temperature, the control component controls the heating component to continue heating or increase heating power so as to increase the actual temperature in the furnace chamber.
In the related art, a temperature sensor is generally disposed on an inner wall of a cavity of an oven, for example, a temperature sensor is disposed in a corner of the oven, and heating power of the oven is controlled according to a measured temperature of the temperature sensor.
According to the temperature control method provided by the application, the temperature in the oven cavity of the oven is detected by using the temperature probe to obtain the first temperature data, so that the first temperature data can truly reflect the temperature of the oven core, the heating power of the oven is controlled according to the first temperature data, the temperature control precision of the oven is improved, and the cooking effect is further improved.
The foregoing description is only a partial embodiment of the present application, and is not intended to limit the scope of the present application, and all equivalent devices or equivalent processes using the descriptions and the drawings of the present application or directly or indirectly applied to other related technical fields are included in the scope of the present application.
