[0039] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person skilled in the art without creative work fall within the scope of protection of the present application.

[0040] The present application provides a temperature measuring assembly, for example, please refer to Figures 1-2 , Figure 1 A structural schematic diagram of the temperature measuring assembly provided by the present application, Figure 2 A structural schematic diagram of the temperature measuring assembly provided by the present application, Figure 1 An exploded view of the temperature measuring assembly shown in the figure. The temperature measuring assembly 100 includes a temperature measuring part 110, a clamping part 120 and a pressing part 130.

[0041] The temperature measuring part 110 includes a temperature measuring contact 111; the clamping part 120 includes oppositely arranged pressing plates 121 and limiting plates 122, and an installation channel 123 between the pressing plates 121 and the limiting plates 122, the installation channel 123 is used for the temperature measuring part 110 to pass through, and the pressing plates 121 are provided with installation holes 1211; the pressing part 130 passes through the installation holes 1211 and partially extends into the installation channel 123, and is used for tightly pressing the temperature measuring contact 111 on the temperature measuring part 110, and making the temperature measuring part 110 abut against the limiting plate 122, wherein the distance between the pressing part 130 and the limiting plate 122 is adjustable.

[0042] The temperature measuring part 110 includes a temperature measuring contact 111; the clamping part 120 includes oppositely arranged pressing plates 121 and limiting plates 122, and an installation channel 123 between the pressing plates 121 and the limiting plates 122, the installation channel 123 is used for the temperature measuring part 110 to pass through, and the pressing plates 121 are provided with installation holes 1211; the pressing part 130 passes through the installation holes 1211 and partially extends into the installation channel 123, and is used for tightly pressing the temperature measuring contact 111 on the temperature measuring part 110, and making the temperature measuring part 110 abut against the limiting plate 122, wherein the distance between the pressing part 130 and the limiting plate 122 is adjustable.

[0043] Optionally, the temperature measuring part 110 is a thermocouple, and the temperature measuring contact 111 is a thermocouple junction.

[0044] In the actual application process, the installer can first increase the distance between the pressing part 130 and the limiting plate 122, so as to facilitate the temperature measuring part 110 to pass through the installation channel 123, and then gradually reduce the distance between the pressing part 130 and the limiting plate 122, until the temperature measuring contact 111 is tightly pressed on the temperature measuring part 110, and the temperature measuring part 110 abuts against the limiting plate 122, to complete the installation.

[0045] The temperature measuring component 100 provided in this application embodiment uses a clamping member 130 to press the temperature measuring contact 111 tightly onto the part to be measured, thereby improving the accuracy of temperature measurement by ensuring reliable contact between the temperature measuring contact 111 and the part to be measured. Furthermore, the clamping member 120 cooperates with the clamping member 130 to improve the structural stability of the clamping member 130, thus ensuring that the temperature measuring member 110 is securely mounted on the part to be measured, solving the problems of difficult installation and low reliability of the temperature measuring member 110 in the refrigerator 10. In addition, since the distance between the clamping member 130 and the limiting plate 122 is adjustable, the width of the installation channel 123 in the first direction H1 can be adjusted by adjusting the relative distance between the clamping member 130 and the limiting plate 122, thereby adapting to parts to be measured of different sizes and improving the versatility of the temperature measuring component 100 in adapting to various scenarios.

[0046] For example, please refer to Figure 2 , Figure 2 for Figure 1 The temperature measuring assembly shown is a cross-sectional view along the AA direction. The temperature measuring element 110 includes a temperature measuring probe 112, the front end of which forms a temperature measuring contact 111; the clamping member 130 has a through hole 131, through which the temperature measuring probe 112 passes, and the temperature measuring contact 111 is at least partially exposed outside the clamping member 130.

[0047] The temperature probe 112 can be either a probe type or a patch type. When the temperature probe 112 is a probe type, for example, when the clamping member 130 abuts against the part to be measured, the temperature measuring contact 111 also abuts against the part to be measured. When the temperature probe 112 is a patch type, the temperature measuring contact 111 is, for example, tightly clamped between the part to be measured and the clamping member 130 so that the temperature measuring contact 111 fits against the part to be measured.

[0048] It should be noted that for the thermocouple-type temperature measuring element 110, the temperature measuring probe 112 includes a thermocouple wire; one of the contacts of the thermocouple wire forms a thermocouple contact, i.e., a temperature measuring contact 111, which is used to contact the element to be measured; the other contact of the thermocouple wire forms a reference contact, which is used to provide a reference temperature for calculating the temperature of the element to be measured; the temperature measuring probe 112 may also include a protective tube, which is usually made of materials such as stainless steel, ceramic, or glass. The protective tube prevents the thermocouple wire from being physically damaged or chemically corroded by wrapping the thermocouple wire inside.

[0049] Understandably, the clamping member 130 has a through hole 131 for the temperature probe 112 to pass through. This is beneficial for the stable installation of the temperature contact 111 and can provide protection for the temperature probe 112. On the other hand, it can also facilitate the wiring of the temperature measuring member 110.

[0050] In some embodiments, please refer toFigure 3 The inner wall of the mounting hole 1211 is provided with a threaded segment (not shown), and the pressing member 130 comprises a threaded rod 132 which is arranged in the mounting hole 1211 and is screwed with the threaded segment, so that the relative distance between the pressing member 130 and the limiting plate 122 can be adjusted.

[0051] To further ensure the reliable contact between the temperature measuring contact 111 and the temperature-measured object, the pressing member 130 can be provided with a pressing block 133 which is connected to the first end of the threaded rod 132, and the temperature measuring contact 111 is fixed on the pressing block 133. Figure 4 Figure 4 The pressing block 133 is used to press the temperature measuring contact 111 against the temperature-measured object, and the cross-sectional area of the pressing block 133 in the axial direction is larger than that of the threaded rod 132. Since the pressing block 133 has a larger cross-sectional area in the axial direction, it is not easy to be misaligned when pressing the temperature measuring contact 111, so that the reliability of the pressing member 130 in pressing the temperature measuring contact 111 against the temperature-measured object can be improved. Preferably, the wall surface of the pressing block 133 which faces the temperature-measured object is conformable to the temperature-measured object. The pressing block 133 can be a square block as shown in FIG. 13B, or can be a cylindrical block, a polygonal block or other shapes. The material of the pressing block 133 can be a flexible material such as silica gel or rubber, or can be plastic, metal or other materials. The pressing block 133 and the threaded rod 132 can be directly glued or integrally injection molded. Figure 4 Optionally, the pressing block 133 and the threaded rod 132 can be connected by an elastic member such as a spring, and when the pressing member 130 presses the temperature measuring contact 111 against the temperature-measured object, the elastic member is compressed. In this way, the elastic member exerts a pressure on the pressing block 133 towards the temperature-measured object, so that the pressing member 130 can press the temperature measuring contact 111 more tightly, and the reliability of the pressing member 130 in pressing the temperature measuring contact 111 against the temperature-measured object can be further improved.

[0052]

[0053] ​​In some embodiments, the clamping plate 121 is adapted to form a limiting groove (not shown) on the inner wall of the mounting hole 1211. The temperature measuring assembly 100 also includes an anti-rotation nut (not shown), which is screwed onto the outside of the threaded rod 132 and adapted to cooperate with the limiting groove to limit the rotation of the clamping member 130. In practical applications, when the clamping member 130 rotates to press the temperature measuring contact 111 tightly onto the part to be measured and to make the part to be measured abut against the limiting plate 122, the anti-rotation nut is assembled into the limiting groove to limit the reverse rotation of the threaded rod 132, so as to prevent the clamping member 130 from reversing and causing the temperature measuring contact 111 and the clamping member 120 to loosen, thus ensuring reliable contact between the temperature measuring contact 111 and the part to be measured.

[0054] In some embodiments, the clamping member 130 further includes a power unit 134 connected to the second end of the threaded rod 132. The power unit 134 is adapted to be held and used to receive external force to drive the threaded rod 132 to rotate. The second end is disposed opposite to the first end. It is understood that the power unit 134 is adapted to be held by an installer or clamped with a tool, and to apply torque to rotate the clamping member 130 until it is rotated to press the temperature measuring contact 111 firmly onto the temperature measuring element and to bring the temperature measuring element abutting against the limiting plate 122. The power unit 134 can be a radially protruding handle, a polygonal stud head, or a polygonal groove. No specific limitation is made here.

[0055] Optionally, a limiting groove is formed on the limiting plate 122. The limiting groove is used to accommodate at least a portion of the temperature-measuring component when it abuts against the limiting plate 122. The limiting groove is adapted to accommodate at least a portion of the temperature-measuring component, and its opposite side walls in the second direction H2 form obstructions to the temperature-measuring component, thereby restricting its movement in the second direction H2. This improves the stability of the installation between the temperature-measuring component and the temperature-measuring assembly 100.

[0056] For example, such as Figure 1 Along the circumference of the mounting channel 123, the limiting plate 122 includes a first plate 1221 and a second plate 1222 bent and connected, forming a limiting groove. It can be understood that along the radial direction of the mounting channel 123, the limiting plate 122 has a herringbone cross-section, and the limiting groove is a through groove extending along the third direction H3. The clamping member 120 also includes, for example, a connecting plate 124. The clamping plate 121, the connecting plate 124, and the limiting plate 122 are bent and connected in sequence to form a C-shaped clamp. When the clamping member 120 is assembled onto the part to be measured, for example, the part to be measured is inserted into the mounting channel 123 through the notch of the clamping member 120.

[0057] In some other embodiments, please refer to Figure 5 , Figure 5Another structural schematic diagram of the temperature measuring assembly provided by the embodiment of the present application is shown. The limiting plate 122 is an arc-shaped plate recessed towards the temperature measuring object, and a limiting groove in the form of a through groove is recessed.

[0058] The temperature measuring assembly 100 provided by the embodiment of the present application uses the pressing member 130 to press the temperature measuring contact 111 against the temperature measuring object, so that the temperature measuring contact 111 reliably contacts the temperature measuring object, thereby improving the temperature measuring accuracy. In addition, the clamping member 120 cooperates with the pressing member 130 to improve the structural stability of the pressing member 130, thereby ensuring that the temperature measuring object 110 is stably arranged on the temperature measuring object, and solving the problems of large installation difficulty and low reliability of the temperature measuring object 110 of the refrigerator 10. In addition, since the distance between the pressing member 130 and the limiting plate 122 is adjustable, the width of the installation channel 123 in the first direction H1 can be adjusted by adjusting the relative distance between the pressing member 130 and the limiting plate 122, thereby adapting to temperature measuring objects of different sizes, and improving the diversity of the adaptation scenarios of the temperature measuring assembly 100.

[0059] The embodiment of the present application also provides a refrigerator. For example, please refer to Figures 6-7 , Figure 6 A structural schematic diagram of the refrigerator provided by the embodiment of the present application is shown. Figure 7 A structural schematic diagram of the temperature measuring assembly provided by the embodiment of the present application arranged on the temperature measuring object is shown. The refrigerator 10 can be a French door refrigerator as shown in Figure 6 The temperature measuring object 200 is suitable for being arranged in the installation channel 123. The temperature measuring object 200 is, for example, a pipeline in a refrigeration system of the refrigerator 10, such as an evaporator inlet and outlet, a gas return pipe, an exhaust pipe, etc.

[0060] The refrigerator 10 provided by the embodiment of the present application uses the above-mentioned temperature measuring assembly 100 to replace the traditional method of sticking a thermocouple with an aluminum foil tape, which can ensure the reliability of temperature measurement of the temperature measuring assembly 100, and solve the problem of large installation difficulty of the temperature measuring object 110 of the refrigerator 10.

[0061] The temperature measuring assembly and the refrigerator provided by the embodiment of the present application are described in detail above, and the principles and implementation manners of the present application are described by applying specific examples. The above description of the embodiments is only used to help understand the method and core idea of the present application; meanwhile, for those skilled in the art, the specific implementation manners and application ranges will be changed according to the idea of the present application. In summary, the content of the specification should not be understood as a limitation of the present application.
