[0001] This application relates to the field of temperature detection technology, specifically to a temperature detection device and a refrigerator. Background Technology

[0002] In existing refrigerator designs, temperature detection devices are commonly installed to achieve precise temperature control in compartments such as the refrigerator and freezer. These devices need to meet sealing and anti-slip requirements to prevent cold air from entering and affecting accuracy; they also need to maintain the cleanliness and aesthetics of the refrigerator's interior. However, current temperature detection devices are typically completely integrated into the refrigerator's inner shell. When the device reaches the end of its lifespan or needs replacement or repair due to other malfunctions, technicians must disassemble the entire inner shell to remove it. The refrigerator's inner shell is usually secured by multiple clips and screws, making disassembly cumbersome and time-consuming. This significantly increases repair time and costs, and inconveniences users. Furthermore, repeated disassembly and reassembly pose a risk of damaging surrounding components or the clip structure, reducing the overall reliability of the product. Utility Model Content

It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion.

[0018] It should be noted that, in the description of this application, the terms "on," "above," "over," and "above" should be interpreted in the broadest sense, meaning that a description containing these terms is interpreted as "a component may be disposed on another component in direct contact, or there may be an intermediate component or layer between the components."

The device may be oriented in other ways (rotated 90° or otherwise), and the spatial relative descriptive terms used in this application can be interpreted accordingly.

[0019] The following describes a temperature detection device provided in an embodiment of this application, with reference to the accompanying drawings. Figure 1-3 The temperature detection device includes a mounting housing 1, a base plate 2, a detection hole 21, and a temperature measuring element 4.

[0020] refer to Figure 1The mounting housing 1 includes a mounting panel 11; a substrate 2 is detachably connected to the mounting housing 1 to form a cavity 3. The outer surface of the mounting panel 11 is flush with the outer surface of the substrate 2, giving the temperature detection device a flat appearance and ensuring its aesthetics; a probe hole 21 is disposed through the substrate 2; a temperature sensing element 4 is connected to the substrate 2 and disposed within the cavity 3. The temperature sensing element 4 includes a temperature sensing area used to acquire ambient temperature. The temperature sensing area is aligned with and exposed to the probe hole 21, allowing the temperature sensing element 4 to acquire ambient temperature through the probe hole 21. After the temperature sensing element 4 is connected to the substrate 2, it can seal the probe hole 21, thus sealing the cavity 3 and preventing external temperature changes from affecting the accuracy of the temperature sensing element 4. In this way, while ensuring the aesthetics of the temperature detection device, the protection requirements for the temperature sensing element 4 are met. Furthermore, the temperature detection device can be easily and quickly disassembled, facilitating independent calibration and replacement of the temperature sensing element 4, thereby improving device maintenance efficiency.

[0021] Specifically, the mounting housing 1 can be fixedly connected to an external device and is used to support the components of the temperature detection device. The mounting housing 1 can protect the temperature sensing element 4 and prevent the temperature sensing element 4 from being mechanically damaged.

[0022] Specifically, the mounting panel 11 is provided with a mounting port, and the substrate 2 is detachably connected to the mounting panel 11 through the mounting port. The shape of the mounting port matches the shape of the substrate 2, so that the gap between the substrate 2 and the mounting port can be reduced after the substrate 2 is connected to the mounting port, which is beneficial to improving the connection sealing between the substrate 2 and the mounting panel 11, and also beneficial to keeping the surface of the substrate 2 and the mounting panel 11 flush.

[0023] In a possible implementation, the size of the mounting panel 11 is larger than the orthogonal projection area of ​​the cavity 3 on the mounting panel 11. Understandably, the temperature detection device can be installed in other equipment or environments to detect the operating temperature of the equipment or the ambient temperature. When the temperature detection device is installed on an external device, the mounting housing 1 can be partially embedded in the mounting position, and the mounting panel 11 and the substrate 2 serve as the external appearance of the entire temperature detection device. In this way, the size of the mounting panel 11 is larger than the orthogonal projection area of ​​the cavity 3 on the mounting panel 11, which can cover the mounting gap and help to increase the aesthetics of the temperature detection device.

[0024] In a possible implementation, the temperature sensing element 4 is detachably connected to the substrate 2; the substrate 2 is provided with a snap-fit ​​groove on the side facing the cavity 3, the snap-fit ​​groove is aligned with the probe hole 21, and the temperature sensing element 4 is snapped into the snap-fit ​​groove to seal the probe hole 21. In this way, it can be ensured that the temperature sensing element 4 will not be displaced or loosened during installation and use; and it is also conducive to accurately positioning the temperature sensing element 4, realizing the modular design of the temperature detection device, and facilitating the individual maintenance and replacement of the temperature sensing element 4.

[0025] In a possible implementation, a receiving sub-cavity is provided on the side of the substrate 2 facing the cavity 3. The detection hole 21 communicates with the receiving sub-cavity, which can accommodate the temperature sensing element 4. After the temperature sensing element 4 is connected to the detection hole 21, the receiving sub-cavity is sealed. In this way, the receiving sub-cavity can isolate the temperature sensing element 4 from other components in the cavity 3, avoiding mechanical damage to the temperature sensing element 4 during installation and use. Furthermore, the receiving sub-cavity and the cavity 3 can work together to protect the temperature sensing element 4, preventing moisture and dirt from adhering to the temperature sensing element 4 and affecting the accuracy of temperature detection.

[0026] Understandably, the temperature sensing element 4 can also be fixedly connected to the substrate 2 to improve the stability of the connection between the temperature sensing element 4 and the substrate 2, and the temperature sensing element 4 can be replaced by replacing the substrate 2.

[0027] In a possible implementation, the temperature sensing element 4 includes a temperature probe, which can collect ambient temperature data. The shape of the temperature probe matches the shape of the detection port. The temperature probe can pass through the detection hole 21 and seal the detection hole 21. Furthermore, the temperature sensing end of the temperature probe is flush with the outer surface of the substrate 2, enabling the temperature probe to accurately detect the temperature at the installation location and ensuring the aesthetic appearance of the substrate 2. Understandably, the temperature probe may not protrude from the outer surface of the substrate 2 to avoid damage to the probe and to prevent affecting the flatness of the surface of the temperature detection device.

[0028] In a possible implementation, the temperature detection device further includes a locking structure 5 disposed in the cavity 3. The mounting housing 1 and the substrate 2 are locked together by the locking structure 5. The locking structure 5 enables quick connection between the substrate 2 and the mounting panel 11. Thus, during the connection process between the substrate 2 and the mounting housing 1, the locking structure 5 can lock the substrate 2 and the mounting housing 1 together, avoiding the use of screws or other structures. The substrate 2 can be installed and disassembled by hand, improving the assembly efficiency of the temperature detection device.

[0029] In some embodiments, the locking structure 5 includes a rotating shaft 51, a locking member 52, and a first elastic member 53. The rotating shaft 51 is fixedly disposed on the substrate 2, and the rotating end of the locking member 52 is rotatably connected to the rotating shaft 51. One end of the first elastic member 53 is fixedly disposed on the substrate 2, and the other end of the first elastic member 53 is connected to the free end of the locking member 52. The free end can abut against the mounting housing 1 based on the elastic action of the first elastic member 53. It can be understood that after the substrate 2 is connected to the mounting housing 1, the first elastic member 53 is in a released state, so that the free end of the locking member 52 is located in the orthographic projection area of ​​the mounting panel 11 and abuts against the inner wall of the mounting panel 11, preventing the substrate 2 from detaching from the mounting panel 11.

[0030] Specifically, during the connection process between the substrate 2 and the mounting panel 11, the rotating end of the locking member 52 can be subjected to pressure from the mounting port. The rotating end of the locking member 52 rotates around the rotating shaft 51 until the first elastic member 53 is compressed. After that, the locking member 52 is located in the orthographic projection area of ​​the substrate 2, so that the locking member 52 can pass through the mounting port and the substrate 2 is connected to the mounting port. After the substrate 2 is connected to the mounting port, the first elastic member 53 is released, and the free end of the locking member 52 can abut against the mounting panel 11 under the elastic action of the first elastic member 53.

[0031] In a possible implementation, a limiting member 12 is provided on the contact surface between the mounting housing 1 and the locking member 52. The limiting member 12 abuts against the locking member 52 and can limit the extreme angle of rotation of the locking member 52. Thus, after the substrate 2 is connected to the mounting housing 1, the limiting member 12 can restrict the movement of the locking member 52, thereby limiting the rotation of the substrate 2 relative to the mounting panel 11. This helps to improve the installation stability of the substrate 2 and avoids frequent rotation of the substrate 2 from affecting the detection accuracy of the temperature detection device.

[0032] Specifically, the limiting member 12 can abut against the side surface of the locking member 52 facing the substrate 2, so that the limiting member 12 can restrict the movement of the locking member 52, thereby restricting the substrate 2 from rotating relative to the mounting panel 11 in the first direction, avoiding frequent rotation of the substrate 2 in the first direction after it is installed in the mounting housing 1, which would affect the stability of the substrate 2's load-bearing structure and the accuracy of temperature detection.

[0033] Specifically, the limiting member 12 can abut against the rotating end of the locking member 52, so that the limiting member 12 can restrict the locking member 52 from rotating around the rotating shaft 51, and at the same time restrict the movement of the substrate 2 in the second direction, so as to prevent the substrate 2 from rotating in the second direction after being installed in the mounting housing 1, causing the substrate 2 to detach from the mounting housing 1. It can be understood that the limiting member 12 can restrict the substrate 2 from rotating without being subjected to external force. When a force is applied to the substrate 2 in the second direction, the locking member 52 can move around the rotating shaft 51 to make the substrate 2 detach from the mounting housing 1, thereby realizing the disassembly of the substrate 2.

[0034] In some embodiments, the second direction can be clockwise and the first direction can be counterclockwise; in some embodiments, the second direction is counterclockwise and the first direction is clockwise; it can be understood that the first direction and the second direction are opposite to each other, and the specific direction referred to by the first direction and the second direction can be determined according to the relative position of the locking member 52 and the limiting member 12.

[0035] Specifically, the locking member 52 is provided with an abutting inclined surface, which is located at the abutting surface between the rotating end of the locking member 52 and the limiting member 12. In this way, the axial force of the limiting member 12 on the locking member 52 can be converted into a radial force, avoiding jamming when the user rotates the substrate 2, and ensuring that the substrate 2 can rotate smoothly relative to the mounting housing 1 under the action of external force.

[0036] In a possible implementation, the substrate 2 can rotate relative to the mounting panel 11, so that the locking member 52, under the constraint of the limiting member 12, rotates toward the substrate 2 until it is located in the orthographic projection area of ​​the substrate 2 after compressing the first elastic member 53. In this way, the restriction of the locking member 52 on the substrate 2 can be released by rotating the substrate 2, and when the locking member 52 is entirely located in the orthographic projection area of ​​the substrate 2, the substrate 2 and the locking member 52 can be detached from the mounting panel 11, thereby realizing the disassembly of the substrate 2.

[0037] In some embodiments, the locking structure 5 includes a locking member 52 and a spring-loaded rotating shaft 51. The spring-loaded rotating shaft 51 is fixedly disposed on the substrate 2, and the rotating end of the locking member 52 is rotatably connected to the spring-loaded rotating shaft 51. During the connection process between the substrate 2 and the mounting panel 11, the locking member 52 is subjected to pressure from the mounting panel 11, causing the locking member 52 to overcome the torque of the spring-loaded rotating shaft 51 and rotate toward the substrate 2 until the locking member 52 is located in the orthographic projection area of ​​the substrate 2, so that the locking member 52 can pass through the mounting opening and the substrate 2 is connected to the mounting opening. After the substrate 2 is connected to the mounting opening, the locking member 52 can rotate to the initial position under the action of the spring-loaded rotating shaft 51 and abut against the mounting panel 11, realizing the simple installation between the substrate 2 and the mounting panel 11.

[0038] Specifically, the locking member 52 has an initial position, which indicates the position of the locking member 52 when it is not subjected to external force. In the initial position, the free end of the locking member 52 protrudes into the orthographic projection area of ​​the substrate 2.

[0039] Specifically, the substrate 2 can rotate relative to the mounting panel 11 so that the locking member 52 rotates toward the substrate 2 under the restriction of the limiting member 12 to the orthogonal projection area of ​​the substrate 2, so that the substrate 2 can be removed from the mounting panel 11; and after the substrate 2 is removed from the mounting panel 11, the locking member 52 can rotate back to the initial position under the action of the spring-loaded pivot 51.

[0040] In a possible implementation, the cavity 3 includes a plurality of opposingly arranged locking structures 5 and limiting members 12. The plurality of locking structures 5 are arranged at intervals around the edge of the substrate 2, and the plurality of limiting members 12 are arranged at positions corresponding to the mounting panel 11 and the locking structures 5. In this way, the substrate 2 and the mounting panel 11 can be locked together by the plurality of matched locking structures 5 and limiting members 12, which is beneficial to improving the locking stability of the substrate 2.

[0041] In a possible implementation, the substrate 2 is threadedly connected to the mounting housing 1, and the edge of the substrate 2 and the mounting opening are provided with matching thread structures.

[0042] In a possible implementation, a second elastic member 7 is provided in the cavity 3. The elasticity of the second elastic member 7 acts on the substrate 2. The direction of the elasticity of the second elastic member 7 intersects the radial direction of the substrate 2, so that the substrate 2 can abut against the mounting panel 11 under the elasticity of the second elastic member 7. This is used to improve the connection strength between the substrate 2 and the mounting panel 11, prevent the substrate 2 from detaching from the mounting panel 11 under external vibration, and at the same time prevent the substrate 2 from falling into the inner cavity of the mounting housing 1.

[0043] In some embodiments, the elastic action direction of the second elastic member 7 intersects with the elastic action of the first elastic member 53. Understandably, the elastic action direction of the first elastic member 53 can be the direction in which the free end of the locking member 52 moves from the substrate 2 to the mounting panel 11. Under the elastic action of the first elastic member 53, the locking member 52 can abut against the mounting panel 11. Thus, the elastic action direction of the second elastic member 7 intersects with the elastic action of the first elastic member 53, making the locking member 52 tightly connected to the mounting panel 11. This helps improve the mounting stability of the substrate 2 and prevents the substrate 2 from shaking or detaching from the mounting panel 11.

[0044] Specifically, the elastic action direction of the second elastic member 7 is perpendicular to the elastic action direction of the first elastic member 53; preferably, the elastic action direction of the first elastic member 53 is parallel to the substrate 2, and the elastic action direction of the second elastic member 7 is perpendicular to the substrate 2, which is beneficial to improve the elastic strength of the second elastic member 7 acting on the substrate 2, thereby improving the installation stability of the substrate 2.

[0045] In a possible implementation, the mounting housing 1 includes a top plate 13 disposed opposite to the mounting panel 11. One end of the second elastic member 7 is connected to the substrate 2, and the other end of the second elastic member 7 abuts against the top plate 13. After the mounting housing 1 is connected to the substrate 2, the second elastic member 7 abuts against the top plate 13 and undergoes elastic compression deformation. It can be understood that when the substrate 2 is detached from the mounting housing 1, the second elastic member 7 is in a free state unaffected by external forces. Thus, one end of the second elastic member 7 is fixed to the substrate 2, preventing the movement of the end of the second elastic member 7 relative to the substrate 2 from affecting the operation of the temperature sensing element 4.

[0046] Specifically, a mounting groove is provided on the side of the substrate 2 facing the cavity 3, and one end of the second elastic member 7 is detachably connected to the mounting groove. The mounting groove can be used to fix the second elastic member 7 and prevent the end of the second elastic member 7 from moving relative to the substrate 2. Preferably, the mounting groove is arranged around the temperature measuring element 4. This is beneficial to optimizing the structural arrangement of the substrate 2, and at the same time, the elastic force of the second elastic member 7 acts on the circumferential direction of the temperature measuring element 4, which is beneficial to improving the installation stability of the temperature measuring element 4.

[0047] In a possible implementation, a foam layer 6 is provided on the side of the mounting panel 11 facing the cavity 3. The foam layer 6 is located near the connection between the mounting panel 11 and the substrate 2. After the mounting panel 11 and the substrate 2 are connected, the foam layer 6 and the substrate 2 are sealed together. The foam layer 6 has good elasticity and damping characteristics. When the temperature detection device is subjected to external vibration or impact, the foam layer 6 can absorb and dissipate some energy, reducing vibration transmission between the mounting panel 11 and the substrate 2. Furthermore, after the mounting panel 11 and the substrate 2 are connected, the locking member 52 can abut against the mounting panel 11 through the foam layer 6. The foam layer 6 deforms under the pressure of the locking member 52, allowing the foam layer 6 to fill the gap between the substrate 2 and the mounting panel 11, ensuring an effective seal between the substrate 2 and the mounting panel 11, and improving the reliability of product installation.

[0048] Specifically, the foam layer 6 is a continuous annular foam structure surrounding the mounting opening of the substrate 2, ensuring good sealing performance between the substrate 2 and the mounting panel 11.

[0049] In a possible implementation, at least one of the substrate 2 and the mounting port is provided with a seal, which can seal the connection between the substrate 2 and the mounting port. Specifically, the seal can be a sealing ring disposed around the edge of the substrate 2. After the substrate 2 is connected to the mounting panel 11, the sealing ring can fill the gap between the substrate 2 and the mounting panel 11, which helps to improve the installation stability of the substrate 2 and at the same time improves the sealing performance of the cavity 3, preventing condensation from forming in the cavity 3 due to external temperature changes and affecting the internal environment of the cavity 3.

[0050] In a possible implementation, a pressing part is provided on the substrate 2, the surface of which is flush with the outer surface of the substrate 2. The pressing part can provide a point of force for the fingers, and the user can rotate the substrate 2 after applying pressure to the pressing part, so as to install and remove the substrate 2 while ensuring that the outer surface of the substrate 2 is simple and beautiful.

[0051] Specifically, the pressing part may include a button groove 8 and a resilient button 9 disposed in the button groove 8. One end of the resilient button 9 is flush with the outer surface of the substrate 2, and the other end of the resilient button 9 is fixedly connected to the button groove 8. By applying pressure to the resilient button 9, the resilient button 9 can be compressed, so that the groove opening of the button groove 8 can be used as a force point to apply a force to rotate the substrate 2. When no pressure is applied, the top of the resilient button 9 can be flush with the outer surface of the substrate 2, ensuring that the surface of the temperature detection device is flat and aesthetically pleasing.

[0052] Specifically, the elastic button 9 includes a third elastic element and a button cap. The button cap is elastically connected to the button slot 8 through the third elastic element. The button cap is flush with the outer surface of the substrate 2. Pressing the button cap can compress the third elastic element. It can be understood that the first elastic element 53, the second elastic element 7, and the third elastic element can be springs with different sizes and elastic forces. The spring sizes can be adjusted according to the actual application requirements.

[0053] Specifically, the substrate 2 is provided with at least two pressing parts. By pressing the two pressing parts with two fingers respectively, the user can rotate the substrate 2, which can effectively improve the convenience of assembling and disassembling the substrate 2.

[0054] This application embodiment also provides a method for assembling and disassembling a temperature detection device. During the process of connecting the substrate 2 to the mounting panel 11, one end of the second elastic member 7 is fixed to the substrate 2, and the other end of the second elastic member 7 abuts against the top plate 13 of the mounting housing 1. The second elastic member 7 is compressed until the rotating end of the locking member 52 is subjected to pressure from the mounting port, causing the rotating end of the locking member 52 to rotate around the rotating shaft 51. After the first elastic member 53 is compressed, the locking member 52 is located in the orthographic projection area of ​​the substrate 2, and the locking member 52 can pass through the mounting port, thereby connecting the substrate 2 to the mounting port. After the substrate 2 is connected to the mounting port, the first elastic member 53 is released, and the free end of the locking member 52 can abut against the mounting panel 11 under the elastic action of the first elastic member 53.

[0055] With the substrate 2 connected to the mounting panel 11, pressure is applied to the pressing part to rotate the substrate 2. The substrate 2 rotates relative to the mounting panel 11, so that the rotating end of the locking member 52 rotates around the rotating axis 51 toward the substrate 2 under the restriction of the limiting member 12. After the first elastic member 53 is compressed, the locking member 52 is located in the orthographic projection area of ​​the substrate 2, and the second elastic member 7 is released, so that the substrate 2 is removed from the mounting panel 11.

[0056] This application also provides a refrigerator, including the temperature detection device described in any of the above embodiments; the temperature detection device can be installed in the inner liner of the refrigerator to detect the working temperature inside the refrigerator, and the temperature sensing element 4 can be easily disassembled and installed by disassembling and installing the base plate 2, and the temperature detection device can be maintained without disassembling the inner liner of the refrigerator.

[0057] Specifically, the refrigerator is provided with a mounting cavity that matches the mounting housing 1. The top plate 13 and side plate of the mounting housing 1 can be fixedly connected to the mounting cavity. The mounting panel 11 and the base plate 2 can form the appearance surface of the temperature monitoring device.

[0058] The foregoing description has fully disclosed the specific embodiments of this application. It should be noted that any modifications made by those skilled in the art to the specific embodiments of this application do not depart from the scope of the claims. Accordingly, the scope of the claims of this application is not limited to the foregoing specific embodiments.
