Description

Technical Field

[0001] This utility model relates to the field of kitchen appliance technology, and in particular to a temperature sensing module and a range hood. Background Technology

[0002] The temperature sensing module on the range hood is used to monitor temperature changes in the cooking area, so as to provide data support for the intelligent operation and safety protection of the range hood.

[0003] Specifically, the structural components of a temperature sensing module mainly include a housing, a panel, a temperature sensing probe assembly, and a temperature sensing mounting base. In traditional designs, the temperature sensing mounting base and the panel are two independent parts, typically connected and secured using snap-fit ​​or screw-fit methods during assembly. However, to reduce the number of parts, injection molding is now used to integrate the temperature sensing mounting base and the panel into a single integral component, thereby reducing production costs and increasing production efficiency. However, after the temperature sensing mounting base and the panel are integrally injection molded, the panel is prone to deformation due to residual stress caused by uneven cooling and shrinkage, resulting in its flatness failing to meet design requirements and a low yield rate. Utility Model Content

[0004] The first technical problem solved by this utility model is to provide a temperature sensing module that can effectively prevent deformation of the panel surface, ensure that the flatness of the panel meets the design standards, and thus ensure the accurate docking of the temperature sensing module in the subsequent assembly process.

[0005] The second technical problem solved by this utility model is to provide a range hood that can effectively prevent deformation of the panel surface, ensure that the flatness of the panel meets the design standards, and thus ensure the accurate docking of the temperature sensing module in the subsequent assembly process.

[0006] The first technical problem mentioned above is solved by the following technical solution: A temperature sensing module for a range hood includes a panel and a temperature sensing probe assembly. The panel has an integrally formed temperature sensing mounting base, which has a through hole penetrating the panel. The temperature sensing probe assembly includes a temperature sensing probe and a PCB board connected to the temperature sensing probe. The temperature sensing probe passes through the through hole and is configured to collect temperature information of the cooking area. The temperature sensing mounting base includes a first wall and a second wall surrounding the first wall. A perforated groove with an opening facing the inside of the range hood is formed between the first wall and the second wall. The first wall serves as the wall of the through hole, and the second wall is used to fix the PCB board.

[0007] Compared with the prior art, the temperature-sensing module of this utility model has the following advantages: By providing a hollowed-out groove on the temperature-sensing mounting base, the thickness of the base wall can be reduced, avoiding an imbalance in cooling rate caused by a large difference between the thickness of the mounting base wall and the panel during the injection molding cooling stage. This allows the thicker areas of the mounting base and the thinner areas of the panel to cool and solidify at relatively similar rates during the injection molding cooling stage. This prevents residual stress in the thicker areas from pulling on the thinner areas, thus preventing warping, dents, and other deformation problems in the panel. This ensures the panel flatness meets design requirements, laying the foundation for precise assembly of the temperature-sensing module. Secondly, the integrated molding of the temperature-sensing mounting base and the panel reduces the number of parts, lowers production costs, and improves the production efficiency of the temperature-sensing module. In addition, this utility model inserts the temperature sensor probe into the through hole, which can block the refraction angle of the temperature sensor probe by using the first wall when the height of the temperature sensor probe is insufficient, thus avoiding excessive magnification of the angle of the temperature sensor probe and obtaining the temperature outside the cooking area. Furthermore, the temperature sensor probe assembly can be fixed by the second wall.

[0008] In one embodiment, the ratio of the wall thickness of the first wall and the wall thickness of the second wall to the thickness of the panel is no greater than 2:1.

[0009] In one embodiment, the PCB board is disposed over the opening of the cutout groove and connected to the second wall via fasteners.

[0010] In one embodiment, there are two temperature sensing probe assemblies and two temperature sensing mounting bases. The temperature sensing probe assemblies and the temperature sensing mounting bases are arranged in a one-to-one correspondence. The temperature acquisition ends of the two temperature sensing probes are tilted away from each other. The tilt direction of the through hole is consistent with the tilt direction of the corresponding temperature sensing probe.

[0011] In one embodiment, the outer sidewalls of the two first walls on the side closest to each other are arranged perpendicularly to the panel, and the remaining outer sidewalls of the first walls are inclined toward the direction corresponding to the axis of the through hole along the direction from the end of the first wall closest to the panel to the end furthest from the panel.

[0012] In one embodiment, the angle θ between the remaining outer walls of the first wall and the perpendicular line of the panel is 6° to 10°.

[0013] In one embodiment, the temperature sensor is perpendicular to the PCB board; along the width direction of the temperature sensor module, two second walls are spaced apart, and along the direction of proximity to each other, the end faces of the two second walls away from the panel are inclined relative to each other.

[0014] In one embodiment, the panel has a mounting groove on the side opposite to the temperature sensor mounting base. The mounting groove is arranged opposite to the two temperature sensor mounting bases. The through hole penetrates the bottom of the mounting groove, and a light-transmitting sheet is installed in the mounting groove.

[0015] In one embodiment, the temperature-sensing mounting base further includes a connecting portion, through which the first wall and the second wall are connected, and the temperature-sensing probe assembly is connected to the temperature-sensing mounting base by fasteners passing through the connecting portion.

[0016] The second technical problem mentioned above is solved by the following technical solution: A range hood includes: a smoke collection hood and the aforementioned temperature sensing module, wherein the temperature sensing module is installed on the side of the smoke collection hood having a smoke inlet and is located on top of the smoke inlet.

[0017] Compared with the prior art, the range hood of this utility model has the following advantages: Compared with conventional range hoods, the range hood equipped with the temperature sensing module of this utility model can effectively collect temperature information of the cooking area, thereby achieving more intelligent and precise operation control. Specifically, the temperature sensing module of this utility model, by providing a hollow groove on the temperature sensing fixing seat, can reduce the thickness of the wall of the temperature sensing fixing seat. This avoids the imbalance of cooling rate caused by the excessive difference between the thickness of the wall of the temperature sensing fixing seat and the thickness of the panel during the injection molding cooling stage. This prevents the residual stress in the thick material area from pulling on the thin material area, causing deformation problems such as panel warping and denting, and ensures that the panel always maintains high precision flatness.

[0025] The following is combined Figures 1 to 7 The following describes embodiments of the present invention.

[0026] According to embodiments of the present invention, on the one hand, such as Figures 1 to 7 As shown, a temperature sensing module 7 is provided for a range hood, including a panel 2 and a temperature sensing probe assembly 3.

[0027] Specifically, the panel 2 is provided with a temperature sensing mounting base 4 integrally formed therewith. The temperature sensing mounting base 4 is provided with a through hole 4021 penetrating through the panel 2. The temperature sensing probe assembly 3 includes a temperature sensing probe 301 and a PCB board 302 connected to the temperature sensing probe 301. The temperature sensing probe 301 is inserted into the through hole 4021 and is configured to collect temperature information of the cooking area. The temperature sensing mounting base 4 includes a first wall 402 and a second wall 403 surrounding the first wall 402. The first wall 402 and the second wall 403 form a hollow groove 401 with an opening facing into the range hood. The first wall 402 is the hole wall of the through hole 4021, and the second wall 403 is used to fix the PCB board 302.

[0028] This embodiment, by providing a hollowed-out groove 401 on the temperature-sensing mounting base 4, can reduce the thickness of the wall of the temperature-sensing mounting base 4, avoiding an imbalance in cooling rate caused by a large difference in the thickness between the wall of the temperature-sensing mounting base 4 and the panel 2 during the injection molding cooling stage. In this way, during the injection molding cooling stage, the thicker areas of the temperature-sensing mounting base 4 and the thinner areas of the panel 2 can complete cooling and solidification at relatively similar rates, thereby preventing residual stress in the thicker areas from pulling on the thinner areas and causing warping, dents, and other deformation problems in the panel 2. This ensures that the flatness of the panel 2 meets design requirements, laying the foundation for the precise assembly of the subsequent temperature-sensing module 7. Secondly, the integral molding of the temperature-sensing mounting base 4 and the panel 2 reduces the number of parts, lowers production costs, and improves the production efficiency of the temperature-sensing module 7. Furthermore, in this embodiment, the temperature sensor 301 is inserted into the through hole 4021. This allows the first wall 402 to shield the temperature sensor 301 from excessive amplification of its angle, preventing it from acquiring temperatures outside the cooking area, even when the sensor's height is insufficient. Secondly, the through hole 4021 on the first wall 402 provides a clear installation reference and guide for the operator. Therefore, repeated calibration is unnecessary during assembly; simply inserting the sensor along the axis of the through hole 4021 allows for quick alignment with the cooking area, reducing installation difficulty and positioning errors, and improving the assembly efficiency and consistency of the temperature sensor module 7. Finally, the through hole 4021 on the first wall 402 ensures that the temperature sensor 301 is relatively stably fixed to the first wall 402, maintaining its preset temperature measurement position and guaranteeing the continuity and stability of temperature acquisition. It also prevents the panel 2 from obstructing the temperature sensor 301, ensuring the accuracy of temperature information acquisition. Additionally, the second wall 403 can fix the temperature sensor assembly 3.

[0029] Furthermore, such as Figure 2As shown, in order to avoid the temperature sensor assembly 3 from coming into contact with oil fumes during operation and to ensure the accuracy of temperature acquisition by the temperature sensor 301, in one embodiment, the temperature sensor module 7 also includes a housing 1, a panel 2 is covered on the housing 1 and together with the housing 1 forms an installation cavity, a temperature sensor mounting base 4 is disposed in the installation cavity, and the temperature sensor assembly 3 is installed in the installation cavity through the temperature sensor mounting base 4.

[0030] Specifically, such as Figure 3 As shown, in this embodiment, there is a gap between the temperature sensing mounting base 4 and the edge of the panel 2, which makes it easier for the panel 2 to cover the housing 1, prevents the temperature sensing mounting base 4 from interfering with the housing 1, and ensures the smooth assembly of the panel 2 and the housing 1.

[0031] Specifically, such as Figure 3 As shown, in this embodiment, the panel 2 and the housing 1 can be connected together by snap-fit ​​or screw-fit, as long as the panel 2 and the housing 1 together form a mounting cavity. This invention does not impose any special limitations on this. Furthermore, to prevent cooking fumes from entering the mounting cavity through the gap between the panel 2 and the housing 1, a sealing element, such as a sealing ring, can be provided at the connection between the panel 2 and the housing 1. This isolates the mounting cavity from the cooking area, providing a safe and reliable working environment for the temperature sensor assembly 3.

[0032] In one embodiment, the ratio of the wall thickness of the first wall 402 and the wall thickness of the second wall 403 to the thickness of the panel 2 is no greater than 2:1. It can be understood that by setting the ratio of the wall thickness of the first wall 402 and the second wall 403 to the thickness of the panel 2 to no greater than 2:1 in this embodiment, it is possible to ensure that the temperature sensing mounting base 4 provides a reliable mounting foundation for the temperature sensing probe assembly 3, preventing loosening of components due to external forces or vibrations during use. Simultaneously, it can reduce the thickness difference between the temperature sensing mounting base 4 and the panel 2, ensuring that the wall thickness of the temperature sensing mounting base 4 in the hollow groove 401 is sufficient to control the residual stress during cooling between 8 MPa and 15 MPa, thus preventing warping, denting, or other deformations of the panel 2 caused by an excessively large thickness difference between the wall thickness of the temperature sensing mounting base 4 and the panel 2.

[0033] It is understood that the ratio of the wall thickness of the first wall 402 to the thickness of the panel 2 can be, but is not limited to, 1.5:1, 1.6:1, 1.7:1, 1.8:1, 1.9:1, 2:1, or any range between the two. Similarly, the ratio of the wall thickness of the second wall 403 to the thickness of the panel 2 can be, but is not limited to, 1.5:1, 1.6:1, 1.7:1, 1.8:1, 1.9:1, 2:1, or any range between the two.

[0034] In one embodiment, such as Figures 2 to 4As shown, the PCB board 302 is installed over the opening of the slot 401 and connected to the second wall 403 via fasteners. It can be understood that this embodiment, by providing the PCB board 302 connected to the temperature sensor 301 and covering the opening of the slot 401 with the PCB board 302, can shield the slot 401, thus achieving physical protection for the temperature sensor 301.

[0035] In one embodiment, such as Figures 2 to 6 As shown, there are two temperature sensor probe assemblies 3 and two temperature sensor mounting bases 4. Each temperature sensor probe 3 and mounting base 4 is set in a one-to-one correspondence. The temperature acquisition ends of the two temperature sensor probes 301 are tilted away from each other, and the tilt direction of the through hole 4021 is consistent with the tilt direction of its corresponding temperature sensor probe 301. Compared to monitoring with a single temperature sensor probe 301, two tilted temperature sensor probes 301 can be aimed at different heating zones of the stove (such as the left and right burners in the cooking area), simultaneously capturing real-time temperature changes in different areas, resulting in more comprehensive temperature acquisition. Furthermore, the consistency between the tilt direction of the through hole 4021 and the temperature sensor probe 301 ensures that the temperature sensor probe 301 is installed precisely at a preset angle, avoiding angular deviations during assembly, while also providing stable tilt support for the probes, preventing angular displacement due to vibration during long-term use, and ensuring continuous and accurate monitoring of their respective target areas.

[0036] In one embodiment, such as Figures 3 to 5 As shown, the outer walls of the two first walls 402 on their adjacent sides are perpendicular to the panel 2. Along the direction from the end of the first wall 402 closest to the panel 2 to the end furthest from the panel 2, the remaining outer walls of the first walls 402 are inclined towards the axis of the corresponding through hole 4021. It is understood that for smooth mold demolding, the first walls 402 need to have a uniform draft angle relative to the panel 2. However, in this embodiment, the temperature sensor 301 needs to be tilted. This requirement causes the two first walls 402 on their adjacent sides to form a draft angle opposite to that of other areas, ultimately causing demolding difficulties. Therefore, this invention, while ensuring good structural strength of the first walls 402, sets an irregular draft angle. That is, the outer walls of the two first walls 402 on their adjacent sides are perpendicular to the panel 2, and the remaining outer walls of the first walls 402 are inclined towards the axis of the corresponding through hole 4021. This eliminates the demolding problem caused by the opposite angles, allowing the mold to complete the demolding operation smoothly.

[0037] In one embodiment, such as Figure 5As shown, the angle θ between the remaining outer walls of the first wall 402 and the perpendicular line of the panel 2 is 6° to 10°. It can be understood that in this embodiment, the included angle is set between 6° and 10°, which can ensure that the first wall 402 can be smoothly removed from the mold after molding, and can avoid excessive demolding resistance due to the included angle being too small, or reduced structural strength due to the included angle being too large.

[0038] It is understood that the angle θ between the remaining outer walls of the first wall 402 and the perpendicular line of the panel 2 can be, but is not limited to, 6°, 7°, 8°, 8.5°, 9°, 10° or any value between the two.

[0039] In one embodiment, such as Figures 3 to 6 As shown, the temperature sensor 301 is perpendicularly positioned to the PCB board 302. Along the width of the temperature sensor module 7, two second walls 403 are spaced apart, and their ends facing away from the panel 2 are inclined relative to each other in the direction of proximity. It can be understood that the relative inclination of the ends facing away from the panel 2 of the two second walls 403 in the direction of proximity, combined with the perpendicular positioning of the temperature sensor 301 to the PCB board, allows the two temperature sensors 301 to naturally present an inclined posture away from each other without additional angle adjustments during assembly, simplifying the assembly process and reducing assembly difficulty.

[0040] In one embodiment, such as Figure 2 As shown, a mounting groove 201 is provided on the side of panel 2 opposite to the temperature sensor mounting base 4. The mounting groove 201 is positioned opposite to the two temperature sensor mounting bases 4, and a through hole 4021 penetrates the bottom of the mounting groove 201. A light-transmitting sheet 5 is installed inside the mounting groove 201. It can be understood that providing the mounting groove 201 on the opposite side of panel 2 and the temperature sensor mounting base 4 provides precise installation and positioning space for the light-transmitting sheet 5, ensuring accurate alignment between the light-transmitting sheet 5, the through hole 4021, and the temperature sensor probe 301, avoiding assembly misalignment that affects performance. Furthermore, the structure of the mounting groove 201 limits and fixes the light-transmitting sheet 5, preventing it from loosening or falling off due to vibration, wiping, or other external forces during long-term use. Secondly, the light-transmitting sheet 5 can effectively isolate impurities such as oil, water vapor, and droplets generated during cooking without obstructing the temperature sensor probe 301 from collecting temperature signals. This prevents impurities from entering the temperature sensor module 7 through the through hole 4021, extending the service life of the temperature sensor module 7 and ensuring temperature detection accuracy.

[0041] Specifically, in this embodiment, the light-transmitting sheet 5 is bonded and fixed in the mounting groove 201 by an adhesive.

[0042] Specifically, the surface of the light-transmitting sheet 5 away from the temperature-sensing mounting base 4 is flush with the opening of the mounting groove 201.

[0043] In one embodiment, such as Figure 3and Figure 4 As shown, the temperature sensing mounting base 4 also includes a connecting part 404. The first wall 402 and the second wall 403 are connected through the connecting part 404. The temperature sensing probe assembly 3 is connected to the temperature sensing mounting base 4 by fasteners passing through the connecting part 404. It can be understood that setting the connecting part 404 in the hollow groove 401 can make the overall structure more compact.

[0044] According to an embodiment of the present invention, on the other hand, as... Figure 1 As shown, a range hood is also provided, including: a smoke collection hood 6 and the aforementioned temperature sensing module 7, wherein the temperature sensing module 7 is installed on the side of the smoke collection hood 6 having a smoke inlet 601 and is located on top of the smoke inlet 601.

[0045] Compared to conventional range hoods, the range hood equipped with the temperature sensing module 7 of this embodiment can effectively collect temperature information of the cooking area, thereby enabling more intelligent and precise operation control. Specifically, the temperature sensing module 7 of this embodiment, by providing a hollow groove 401 on the temperature sensing mounting base 4, can reduce the thickness of the wall of the temperature sensing mounting base 4. This avoids the imbalance of cooling rate caused by the excessive difference between the thickness of the wall of the temperature sensing mounting base 4 and the thickness of the panel 2 during the injection molding cooling stage. This prevents the residual stress in the thicker material area from pulling on the thinner material area, causing deformation problems such as warping and denting of the panel 2, and ensuring that the panel 2 always maintains a high precision flatness.

[0046] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.

[0047] The specific embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
