Description

Technical Field

[0001] This application relates to the field of sensor technology, and in particular to an absolute temperature and humidity sensor with a novel structure. Background Technology

[0002] Absolute humidity and absolute temperature sensors significantly improve cooking results and energy efficiency in home and commercial high-temperature cooking equipment (such as ovens, steam ovens, and air fryers) through precise monitoring and dynamic control. Absolute temperature sensors detect the cavity temperature in real time, avoiding uneven heating or overheating caused by traditional temperature differences, ensuring stable heating of food, which is especially crucial for baking and roasting, where strict temperature control is required. Absolute humidity sensors analyze water vapor content and intelligently adjust steam volume or hot air circulation during steaming, baking, or air frying, maintaining the internal moisture of food while creating a crispy outer layer, balancing taste and efficiency. Their collaborative operation supports automated operation, reducing human intervention, while optimizing heating and humidity strategies to reduce energy consumption and extend equipment lifespan. Balancing accuracy, safety, and energy efficiency in high-temperature environments, they provide reliable technical support for modern intelligent cooking.

[0003] Chinese utility model patent, publication number CN220854724U, discloses an absolute humidity sensor, which includes a shell, a bottom cover, a non-sealed thermistor assembly, and a sealed thermistor assembly. The bottom cover is connected to the bottom of the shell, forming a cavity between the bottom cover and the shell. The non-sealed and sealed thermistor assemblies are installed in the cavity between the bottom cover and the shell. First mounting plates are respectively provided on both sides of the shell, with first mounting holes on the first mounting plates. Second mounting plates are respectively provided on both sides of the bottom cover, with second mounting holes corresponding to the first mounting holes. Mounting nuts are threaded onto both ends of mounting bolts. The shell and bottom cover are joined together, and the mounting bolts pass through the first and second mounting holes. The two mounting nuts are respectively installed on both ends of the mounting bolts, fixing the shell and bottom cover together. When it is necessary to separate the shell and bottom cover to inspect and maintain the components inside the sensor, the mounting nuts are detached from the mounting bolts, facilitating sensor disassembly and demonstrating high practicality.

[0004] In this patent, a first sensor sealing cap is welded to a first welding base, and a first thermistor is located inside the first sensor sealing cap and welded to the first welding base. The first welding base is installed inside the housing, and the first welding base fixes the first sensor sealing cap and the first thermistor to achieve humidity measurement of electrical equipment. In practical applications, the inventors found that because the first sensor and the first thermistor are directly welded to the first welding base, when the electrical equipment is working, the temperature and humidity experienced by the first welding base are the same as those experienced by the first thermistor and the first sensor. With the increase of usage time, the weld joints of the first welding base and the first thermistor and the first sensor will be corroded by liquids, water vapor and / or oil stains, indicating room for improvement. Utility Model Content

[0005] To reduce the probability of liquids, moisture, and / or oil stains affecting the normal operation of the sensor, this application provides an absolute temperature and humidity sensor with a novel structure.

[0006] This application provides a novel absolute temperature and humidity sensor using the following technical solution:

[0007] A novel absolute temperature and humidity sensor includes a protective cover, a sensor mounting base, a sealing element, and a base mounting bracket. The protective cover has an internal cavity. The base mounting bracket includes a first fixed base and a second fixed base, which are fixedly connected. The protective cover is fixedly connected to the first fixed base. A humidity sensor is mounted on the sensor mounting base. When the protective cover is closed onto the first fixed base, the sensor mounting base is located within the cavity. The sealing element is located between the sensor mounting base and the first fixed base, and it abuts against the humidity sensor. The second fixed base is used for fixed connection with a cooking device.

[0008] By adopting the above technical solution, the sealing component is used to seal the sensor mounting base and the first fixing base, and the second fixing base is used to fix it to the cooking equipment. This effectively reduces the probability of damage caused by the components and wire soldering points on the sensor mounting base coming into contact with liquids, water vapor and / or oil stains generated when the cooking equipment is working.

[0009] Preferably, the first fixing seat and the second fixing seat are provided with a wire outlet hole along the same axis.

[0010] By adopting the above technical solution, since the first and second fixing seats are provided with outlet holes along the same axis, the purpose of axial rear outlet is achieved, so as to facilitate its installation on cooking equipment, reduce the exposure of wires, and also reduce the probability of the wires being directly exposed to high temperatures and affecting the performance of the wires as the working time increases.

[0011] Preferably, the protective cover is fixedly connected to the second fixing seat, and the sealing element is located between the sensor mounting seat and the second fixing seat.

[0012] By adopting the above technical solution, the protective cover is directly fixed to the second fixed base, which helps to reduce the overall size and increase the overall flexibility.

[0013] Preferably, a temperature sensor is provided on the sensor mounting base.

[0014] By adopting the above technical solution, since the sensor mounting base is also equipped with a temperature sensor, the temperature of the cooking equipment during operation is detected by the temperature sensor. In combination with the humidity sensor, the purpose of detecting the temperature and humidity of the cooking equipment during operation is achieved simultaneously, without the need to install a single temperature detection component inside the cooking equipment. This plays a positive guiding role in improving the space utilization rate inside the cooking equipment.

[0015] Preferably, a sealing ring is provided on the second fixing seat, the sealing ring being used to seal the connection surface between the second fixing seat and the cooking equipment.

[0016] By adopting the above technical solution, the sealing ring is used to seal the second fixed seat and the cooking equipment, thereby reducing the probability of liquid, water vapor and / or oil stains entering the interior of the cooking equipment.

[0017] Preferably, a heat insulation sleeve is provided inside the outlet hole.

[0018] By adopting the above technical solution and protecting the wires with heat insulation sleeves, the probability of damage to the wires caused by the high amount of heat conducted to the wires during operation of the cooking equipment is reduced.

[0019] Preferably, the protective cover is provided with a flange, which is used to fasten the protective cover and the first fixing seat.

[0020] By adopting the above technical solution, the protective cover and the first fixed seat can be fixedly connected by flipping the edge, without the need for other mechanical structures to fix the first fixed seat and the protective cover. The mechanical structure is simple and has high stability.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. By using a sealing element to seal the space between the sensor mounting base and the first fixed base, the probability of damage to the components and wire solder joints on the sensor mounting base from liquids, moisture and / or oil stains generated during the operation of the cooking equipment is effectively reduced.

[0023] 2. Because the first and second fixing seats are provided with wire outlet holes along the same axis, the purpose of axial rearward appearance is achieved, so as to facilitate installation on the cooking equipment, and at the same time, it provides a certain protection for the wires;

[0024] 3. Because the sensor mounting base is also equipped with a temperature sensor, it can work in conjunction with a humidity sensor to simultaneously detect the temperature and humidity of the cooking equipment during operation, without having to install a single temperature detection component inside the cooking equipment. This has a positive effect on improving the space utilization of the cooking equipment. Attached Figure Description

[0033] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0034] This application discloses a novel absolute temperature and humidity sensor.

[0035] Example 1

[0036] Reference Figures 1-4 A novel absolute temperature and humidity sensor includes a protective cover 1, a sensor mounting base 2, a sealing element 3, and a base mounting bracket 4. The protective cover 1 has a cavity 11 inside and a vent hole 104 on it to allow heat and / or moisture to enter the cavity 11. The base mounting bracket 4 includes a first fixing base 41 and a second fixing base 42, which are fixedly connected. The protective cover 1 is fixedly connected to the first fixing base 41. A humidity sensor 5 is mounted on the sensor mounting base 2. When the protective cover 1 is closed on the first fixing base 41, the sensor mounting base 2 is located inside the cavity 11. The sealing element 3 is located between the sensor mounting base 2 and the first fixing base 41 and abuts against the humidity sensor 5. The second fixing base 42 is used to fix it to a cooking device.

[0037] Specifically, a support rod 10 is provided between the first fixed seat 41 and the second fixed seat 42. The first fixed seat 41 is located on one end of the support rod 10, and the second fixed seat 42 is located in the area between the first fixed seat 41 and the other end of the support rod 10. The first fixed seat 41 and the second fixed seat 42 are coaxially arranged with the support rod 10, and the first fixed seat 41, the support rod 10 and the second fixed seat 42 are integrally formed.

[0038] Furthermore, the seal 3 can be made of polytetrafluoroethylene (PTFE) and its composites, fluororubber (such as VITON series), or other materials with high temperature resistance and corrosion resistance. In this embodiment, preferably, the seal 3 is made of silicone. The silicone material has the characteristics of high temperature resistance, corrosion resistance and softness, which is beneficial to filling the gap between the sensor mounting base 2 and the first fixing base 41, thereby improving the sealing performance and reducing the probability of damage caused by the components and wire soldering points on the sensor mounting base 2 coming into contact with liquids, water vapor and / or oil stains generated when the cooking equipment is working.

[0039] Meanwhile, the first fixing base 41 and the second fixing base 42 are provided with wire outlet holes 6 along the same axis. The wire outlet holes 6 are formed by the support rod 10 penetrating through the end face in the length direction. After the humidity sensor 5 is installed on the sensor mounting base 2, the wire connecting the humidity sensor 5 passes through the wire outlet holes 6, realizing the purpose of axial rear wire outlet. This makes it easier to install it on the cooking equipment, reducing the exposure of the wires. It also reduces the probability of the wires being directly exposed to high temperatures and affecting the performance of the wires as the working time increases.

[0040] Correspondingly, a heat insulation sleeve 9 is installed inside the outlet hole 6. The wire is passed through the heat insulation sleeve 9. The heat insulation sleeve 9 protects the wire and reduces the probability of the heat conducted to the wire during the operation of the cooking equipment causing damage to the wire.

[0041] In addition, a sealing ring 8 is provided on the second fixing seat 42. The material of the sealing ring 8 can be the same as that of the sealing element 3. The sealing ring 8 is used to seal the connection surface between the second fixing seat 42 and the cooking equipment, thereby reducing the probability of liquid, water vapor and / or oil stains entering the interior of the cooking equipment.

[0042] On the other hand, in this embodiment, the protective cover 1 is made of metal, giving it high-temperature resistance. The protective cover 1 is provided with a flange 101, which is used to fasten the protective cover 1 and the first fixing seat 41. The flange 101 extends from the edge of the protective cover 1 towards the sensor mounting seat 2. When the protective cover 1 is placed on the first fixing seat 41, external force is used to fold the flange 101, thereby fastening the flange 101 to the first fixing seat 41. No other mechanical structure is needed to fix the first fixing seat 41 and the protective cover 1; the mechanical structure is simple and highly stable.

[0043] It should also be noted that the shape of the protective cover 1 can be changed according to actual needs or design requirements, such as cylindrical, rectangular or other irregular shapes to adapt to cooking equipment, and its specific shape is not limited here.

[0044] The implementation principle of Example 1 is as follows: the sealing element 3 is used to seal the sensor mounting base 2 and the first fixed base 41, and the second fixed base 42 is used to fix the sensor mounting base 2 to the cooking equipment. This effectively reduces the probability of damage caused by the components and wire soldering points on the sensor mounting base 2 coming into contact with liquids, water vapor and / or oil stains generated when the cooking equipment is working.

[0045] Example 2

[0046] The difference between Example 2 and Example 1 is that, referring to... Figure 5 and Figure 6 The protective cover 1 is connected to the second fixed seat 42, and the sealing element 3 is located between the sensor mounting seat 2 and the second fixed seat 42.

[0047] In this embodiment, the first fixing seat 41 in Embodiment 1 is omitted, and the protective cover 1 is directly connected to the second fixing seat 42.

[0048] Specifically, in this embodiment, the flange 101 can be integrally formed with the protective cover 1, or the flange 101 can be integrally formed with the second fixing seat 42 (the forming methods are the same and will not be described in detail here). In this embodiment, the flange 101 and the second fixing seat 42 are integrally formed to achieve the purpose of interlocking the protective cover 1 and the second fixing seat 42.

[0049] Furthermore, the second fixing base 42 and the protective cover 1 are respectively integrally formed with mounting ears 102 at their edges. The mounting ears 102 are provided with mounting holes 103. When the protective cover 1 is covered by the second fixing base 42, the mounting ears 102 on the protective cover 1 and the mounting ears 102 on the second fixing base 42 are aligned and can be fixed to the cooking equipment using bolts or rivets.

[0050] The implementation principle of Example 2 is as follows: the protective cover 1 is directly fixedly connected to the second fixed base 42, which helps to reduce the overall size and increase the overall flexibility.

[0051] Example 3

[0052] The difference between Example 3 and Examples 1 and 2 is that, referring to... Figure 7 The sensor mounting base 2 is equipped with a temperature sensor 7, which can be selected according to usage or design requirements, offering high flexibility.

[0053] The implementation principle of Example 3 is as follows: Since a temperature sensor 7 is also provided on the sensor mounting base 2, the temperature of the cooking equipment during operation is detected by the temperature sensor 7. By cooperating with the humidity sensor 5, the purpose of detecting the temperature and humidity of the cooking equipment during operation is achieved simultaneously, without the need to install a single temperature detection component inside the cooking equipment. This plays a positive guiding role in improving the space utilization rate inside the cooking equipment.

[0054] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
