Description

Technical Field

[0001] The present application relates to the technical field of refrigeration equipment, for example, to a temperature sensing tube and a refrigerator. Background Art

[0002] The temperature control of the refrigerator is usually achieved through a temperature sensing tube and a thermostat. The temperature sensing tube is used to detect the ambient temperature and transmit the temperature signal to the thermostat, which then controls the start or shut down of the compressor. In the actual production of refrigerators, manufacturers will design refrigerator bodies with different foam layer thicknesses according to market demand. During the assembly of the refrigerator, the temperature sensing tube is first installed on the outer side of the inner tank, and then the inner tank with the temperature sensing tube is placed in the preset position of the outer shell according to the preset foam layer thickness, and then the inner tank is moved horizontally to make the temperature sensing tube pass through the reserved perforation on the cabin partition, and then the temperature sensing probe of the thermostat is inserted into the temperature sensing tube, and the thermostat is set in the compressor compartment. If the temperature sensing tube is tightly connected to the inner tank and the position is accurate, it will ensure that the temperature sensing probe of the thermostat is stable and sensitive to temperature, which will have a good control over the start and stop of the compressor and reduce the energy consumption of the refrigerator. Therefore, it is particularly important to accurately set the temperature sensing tube.

[0003] During the assembly process of the refrigerator, in order to ensure that the temperature-sensing tube is tightly connected to the inner tank, one end of the temperature-sensing tube can face the perforation of the cabin partition to achieve precise setting of the temperature-sensing tube. Usually, the corresponding type of cabin partition is used according to the preset foam layer thickness. The perforations of different types of cabin partitions are located in different positions. Different types of cabin partitions are selected for refrigerators with different foam layer thicknesses to achieve precise assembly between the cabin partition, the temperature-sensing tube and the inner tank. Another solution is to open multiple holes in the cabin partition according to different foam layer thicknesses. During the assembly process, according to the different foam layer thicknesses, the temperature-sensing tube is passed through different perforations to achieve precise assembly between the cabin partition, the temperature-sensing tube and the inner tank.

[0004] However, in the above scheme, the actual difference between different models of cabin partitions is only the position of a hole. When producing cabin partitions of different models, the precision requirements are extremely high, and even if precision errors occur, it is difficult to distinguish them with the naked eye. During the assembly process, the models of cabin partitions also need to be distinguished one by one. Due to model identification errors or errors in the perforation position of the cabin partition, it is easy to cause mismatches between the cabin partition, the temperature sensing tube and the inner liner, resulting in low assembly accuracy of the temperature sensing tube and poor connection effect of the temperature sensing tube. In actual operation, after the inner liner is placed in the box shell, it is difficult for the assembler to see the position of the temperature sensing tube and the position of the installation hole of the cabin partition. Therefore, when using a cabin partition with multiple holes to assemble a refrigerator, the temperature sensing tube often has the wrong hole, resulting in mismatches between the cabin partition, the temperature sensing tube and the inner liner, resulting in low assembly accuracy of the temperature sensing tube and poor connection effect of the temperature sensing tube. In summary, in the related art, the solutions of setting different types of cabin partitions or opening multiple holes in the cabin partitions have the disadvantages of low adaptability and assembly accuracy during the installation of the temperature sensing tube of the refrigerator. Therefore, how to improve the adaptability between the cabin partition, the temperature sensing tube and the inner tank, and how to improve the assembly accuracy of the temperature sensing tube need to be solved urgently.

[0005] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present application, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field.

By improving the adaptation between the cabin partition, the temperature sensing tube and the inner tank, the assembly accuracy of the temperature sensing tube is improved. In addition, since in the process of assembling the refrigerator using the temperature sensing tube provided by the present invention, it is not necessary to distinguish the model of the cabin partition or the position of the perforation, the assembly efficiency of the refrigerator is improved.

[0047] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0048] In some embodiments, in combination Figures 1 to 3 As shown, a temperature sensing tube 1 is provided, comprising a main pipe 10 and an extension pipe 20. The cross section of the main pipe 10 is a regular polygon. The extension pipe 20 is connected to one end of the main pipe 10, and the cross section of the extension pipe 20 is circular. The extension pipe 20 comprises an extension portion 210, the axis of the extension portion 210 and the axis of the main pipe 10 are parallel to each other, and the extension portion 210 and the main pipe 10 are staggered.

[0049] The temperature sensing tube 1 provided by the present disclosure is used for a refrigerator. Since the axis of the extension part 210 of the temperature sensing tube 1 is parallel to the axis of the main tube 10, and the extension part 210 and the main tube 10 are staggered, a gap is formed between the plane where the axis of the extension part 210 is located and the plane where the axis of the main tube 10 is located. The cross section of the main tube 10 is a regular polygon, and the gap between the plane where the axis of the extension part 210 is located and the plane where the axis of the main tube 10 is located can be changed by rotating the main tube 10.

[0050] Compared with the related art, the present invention adopts a redesign of the structure of the temperature sensing tube 1, the main pipe 10 is used to connect with the inner tank, and the extension part 210 is used to pass through the cabin partition and connect with the thermostat. Using the temperature sensing tube 1 provided by the present invention, even if the perforation position of the cabin partition is fixed, facing refrigerators with different foam layer thicknesses, by changing the distance between the plane where the axis of the extension part 210 is located and the plane where the axis of the main pipe 10 is located, the position deviation between the perforation of the inner tank and the cabin partition caused by the change in the thickness of the foam layer can be offset, thereby improving the adaptation rate of the temperature sensing tube 1 and improving the adaptation between the cabin partition, the temperature sensing tube 1 and the inner tank. By improving the adaptation between the cabin partition, the temperature sensing tube 1 and the inner tank, the assembly accuracy of the temperature sensing tube 1 is improved. In addition, since it is not necessary to distinguish the model of the cabin partition or the position of the perforation during the assembly of the refrigerator using the temperature sensing tube 1 provided by the present invention, the assembly efficiency of the refrigerator is improved.

[0051] Optionally, combined Figure 1 and Figure 2 As shown, the extension tube 20 further includes a bending portion 220. The extension portion 210 and the main tube 10 are respectively disposed at opposite ends of the bending portion 220, and the extension portion 210 and the main tube 10 are staggered through the bending portion 220.

[0052] In this embodiment, the main pipe 10, the bending portion 220 and the extension portion 210 are sequentially connected to form the temperature sensing pipe 1. Figures 2 to 4 As shown, the extension part 210 and the main pipe 10 are staggered by the bending part 220, so that a staggered spacing L is formed between the axis of the extension part 210 and the axis of the main pipe 10, and the length of the staggered spacing L is fixed. By rotating the main pipe 10, the spacing M between the plane where the axis of the extension part 210 is located and the plane where the axis of the main pipe 10 is located can be changed, so that during the assembly process of the refrigerator, the cabin partition, the temperature sensing pipe 1 and the liner can be assembled to adapt to different foaming layer thicknesses.

[0053] Optionally, combined Figure 1 and Figure 2 As shown, the bending portion 220 includes a first connection portion 222 and a second connection portion 224. The second connection portion 224 and the main pipe 10 are respectively disposed at opposite ends of the first connection portion 222, and the first connection portion 222 and the extension portion 210 are respectively disposed at opposite ends of the second connection portion 224.

[0054] In this embodiment, the main pipe 10, the first connection part 222, the second connection part 224 and the extension part 210 are connected and arranged in sequence to form a temperature sensing tube 1. The main pipe 10 and the first connection part 222 are arranged coaxially. An angle θ is formed between the axis of the first connection part 222 and the axis of the second connection part 224. The staggered arrangement between the extension part 210 and the main pipe 10 is achieved by the angle formed between the axis of the first connection part 222 and the axis of the second connection part 224. In addition, an angle β is formed between the axis of the second connection part 224 and the axis of the extension part 210, and the sum of the angle θ and the angle β is 180°. By limiting the sum of the angle θ and the angle β to 180°, the axis of the extension part 210 and the axis of the main pipe 10 are parallel to each other.

[0055] Optionally, combined Figure 1 and Figure 2 As shown, the angle between the first connection portion 222 and the second connection portion 224 is a right angle or an obtuse angle. The angle between the second connection portion 224 and the extension portion 210 is a right angle or an obtuse angle.

[0056] In this embodiment, the angle θ between the first connection portion 222 and the second connection portion 224 is a right angle or an obtuse angle, and the angle β between the second connection portion 224 and the extension portion 210 is a right angle or an obtuse angle. Specifically, when the angle θ is a right angle, the angle β is a right angle. When the angle θ is an obtuse angle, the angle β is an acute angle. By limiting the angle θ to be a right angle when the angle θ is a right angle and the angle β to be an acute angle when the angle θ is an obtuse angle, the sum of the angle θ and the angle β is limited to 180°, so that the axis of the extension portion 210 and the axis of the main pipe 10 are parallel to each other.

[0057] Optionally, the distance between the axis of the extension portion 210 and the axis of the main pipe 10 is L, 10 mm ≤ L ≤ 50 mm.

[0058] In this embodiment, L represents the distance between the axis of the extension part 210 and the axis of the main pipe 10. By limiting 10mm≤L≤50mm, it is avoided that the distance between the axis of the extension part 210 and the axis of the main pipe 10 is too large, exceeding the thickness of the foam layer, which is not conducive to the assembly of the temperature sensing tube 1 on the inner tank and the cabin partition. In addition, by limiting 10mm≤L≤50mm, it is avoided that the distance between the axis of the extension part 210 and the axis of the main pipe 10 is too small, resulting in a small adjustable range of the distance between the plane where the axis of the extension part 210 and the plane where the axis of the main pipe 10 are located, thereby causing the temperature sensing tube 1 to be unable to adapt to the refrigerator with a large change in the thickness of the foam layer, thereby reducing the adaptation rate of the temperature sensing tube 1. Exemplarily, the value of L is 10mm, 20mm, 30mm, 40mm or 50mm.

[0059] Optionally, the regular polygon includes a regular triangle, a square, a regular pentagon, a regular hexagon or a regular octagon.

[0060] In this embodiment, the cross section of the main tube 10 is a regular polygon, and the regular polygon can be an equilateral triangle, a square, a regular pentagon, a regular hexagon or a regular octagon. Regular polygons of different shapes have different angles between adjacent sides, and their corresponding complementary angles α are also different, α=360 / n, n represents the number of sides of the regular polygon. Exemplarily, when the regular polygon is an equilateral triangle, the angle between its adjacent sides is 60°, and its corresponding complementary angle α is 120°. When the regular polygon is a regular hexagon, the angle between its adjacent sides is 120°, and its corresponding complementary angle α is 60°.

[0061] It should be noted that the specific shape of the cross section of the main pipe 10 is not limited here, as long as the cross section of the main pipe 10 satisfies the condition of being a regular polygon. This application only provides some embodiments.

[0062] Combination Figure 3 and Figure 4 As shown, during the rotation of the main tube 10, the complementary angle α is the rotation angle. According to the rotation angle α, the distance M between the plane where the axis of the extension part 210 is located and the plane where the axis of the main tube 10 is located, and the displacement N of the axis of the extension part 210 along the Y direction due to the rotation of the main tube 10 can be calculated. Figure 4 As shown, the main pipe is rotated to rotate the main pipe by an angle α, so that the temperature sensing pipe is rotated from position e to position f. When the temperature sensing pipe is rotated to position f, according to the trigonometric function calculation formula, the displacement N=L-Lcosα of the axis of the extension part 210 along the Y direction is obtained, and the distance M=LN=Lcosα between the plane where the axis of the extension part 210 is located and the plane where the axis of the main pipe 10 is located. By calculating the distance M and the displacement N, the main pipe 10 can be adaptively rotated during the assembly of the refrigerator, so as to assemble the cabin partition, the temperature sensing pipe 1 and the inner tank according to different foam layer thicknesses.

[0063] Optionally, combined Figure 1 and Figure 3 As shown, the main pipe 10 includes a plurality of side walls 110 , and the plurality of side walls 110 are sequentially connected along the circumferential direction.

[0064] In this embodiment, the multiple side walls 110 of the main pipe 10 are connected in sequence along the circumferential direction. The side walls 110 serve as connecting surfaces. When the main pipe 10 is assembled in the inner tank, it is connected to the inner tank and used to detect the ambient temperature. Compared with the related art, in which the long round bar main pipe is in line contact with the side wall of the inner tank, the main pipe 10 is set as a structural form in which the multiple side walls 110 are connected in sequence along the circumferential direction, so that the contact form between the main pipe 10 and the side wall of the inner tank is surface contact. Compared with the related art, the heat conduction area of ​​the main pipe 10 is increased, and the temperature sensitivity of the main pipe 10 is improved.

[0065] Optionally, combined Figure 1 and Figure 3 As shown, the number of side walls 110 is the same as the number of sides of the regular polygon.

[0066] In this embodiment, the number of the side walls 110 is the same as the number of sides of the regular polygon, and the plurality of side walls 110 are sequentially connected along the circumferential direction, so that the cross section of the main pipe 10 is a regular polygon.

[0067] In some embodiments, in combination Figures 5 to 8 As shown, a cold cabinet 3 is provided, comprising a cabinet body 40, a cabin partition 50, an inner liner 60, and a temperature sensing tube 1 as described in any of the above embodiments. The cabin partition 50 is connected to the cabinet body 40, and the cabin partition 50 is used to separate the cabinet body 40 into a storage compartment 410 and an installation cavity 420, and the cabin partition 50 includes a temperature sensing guide hole 510. The inner liner 60 is arranged in the storage compartment 410. In the temperature sensing tube 1 as described in any of the above embodiments, the side wall 110 of the main pipe 10 is connected to the inner liner 60, and the extension portion 210 extends into the installation cavity 420 through the temperature sensing guide hole 510.

[0068] The refrigerator 3 provided in the embodiment of the present disclosure is equipped with the temperature sensing tube 1 as described in any of the above embodiments, wherein the side wall 110 of the main pipe 10 is connected to the inner liner 60, so that the side wall 110 of the main pipe 10 is fitted to the side wall of the inner liner 60. Compared with the line contact between the temperature sensing tube 1 and the side wall of the inner liner 60 in the related art, the surface contact between the temperature sensing tube 1 and the side wall of the inner liner 60 is achieved by making the side wall 110 of the main pipe 10 fit to the side wall of the inner liner 60. By converting the contact form between the temperature sensing tube 1 and the side wall of the inner liner 60 into surface contact, the heat conduction efficiency between the temperature sensing tube 1 and the inner liner is improved, and the temperature sensitivity of the refrigerator 3 is improved.

[0069] In addition, the temperature sensing tube 1 provided by the present disclosure can be adapted to refrigerators 3 with different foam layer thicknesses, reducing the precision requirements for the cabin partition 50. During the assembly of the refrigerator 3, there is no need to distinguish the model or perforation position of the cabin partition 50, thereby improving the assembly efficiency of the refrigerator 3.

[0070] For example, in combination Figure 7 and Figure 8As shown, a freezer 3 with preset foam layer thicknesses of A and B is taken as an example, where A>B. A=3L, B=2.5L. For a freezer 3 with different foam layer thicknesses of A and B, a regular hexagonal (n=6) temperature sensing tube 1 is selected for assembly, and the rotation angle α of the temperature sensing tube 1 is 60°.

[0071] Combination Figure 7 As shown, the refrigerator 3 is assembled based on the thickness A. First, the corresponding model of the cabin partition 50 is installed on the box body to separate the storage compartment 410 and the installation cavity 420. At the same time, the temperature sensing tube 1 is installed on the side wall of the inner liner 60, so that the side wall 110 of the temperature sensing tube 1 is connected to the side wall of the inner liner 60. Since the model of the cabin partition 50 matches the thickness A of the foam layer in this case, the temperature sensing tube 1 is set so that the axis of the main pipe 10 coincides with the axis of the extension part 210 along the X-axis direction. Then, the assembled inner liner 60 and the temperature sensing tube 1 are placed in the storage compartment 410, and the inner liner 60 is moved horizontally to make the temperature sensing tube 1 pass through the temperature sensing guide hole 510 on the cabin partition 50 to realize the assembly of the refrigerator 3.

[0072] Combination Figure 8 As shown, when the thickness of the foam layer of the refrigerator 3 is B, due to the change in the thickness of the foam layer, the side wall of the inner liner 60 moves Δ=AB=0.5L in the opposite direction of the X-axis. Since the model of the cabin partition 50 remains unchanged, the temperature-sensing guide hole 510 and the side wall of the inner liner 60 produce a displacement deviation G=Δ=0.5L in the X-axis direction. Then the main pipe 10 is rotated to change the connection surface between the main pipe 10 and the side wall of the inner liner 60 so that the spacing M=G=0.5L. Since M=Lcosα, α=60° is calculated. Compared with the case where the thickness of the foam layer is A, the main pipe 10 is rotated 60° and then connected to the inner liner 60. Then the assembled inner liner 60 and the temperature-sensing tube 1 are placed in the storage compartment 410, and the inner liner 60 is moved horizontally to make the temperature-sensing tube 1 pass through the temperature-sensing guide hole 510 on the cabin partition 50 to realize the assembly of the refrigerator 3.

[0073] Optionally, the refrigerator 3 further includes a thermostat, which is located in the installation cavity 420 and connected to the extension portion 210 .

[0074] In this embodiment, the thermostat includes a thermostat probe, which is inserted into the extension part 210 to realize the connection between the thermostat and the extension part 210, and to realize the assembly of the thermostat and the temperature sensing tube 1. The temperature sensing tube 1 is used to detect the ambient temperature and transmit the temperature signal to the thermostat, and the thermostat is used to control the start or stop of the refrigeration function of the refrigerator 3 according to the temperature signal.

[0075] Optionally, combined Figure 7 and Figure 8 As shown, a heat preservation chamber 610 is defined between the cabinet body 40 and the inner tank 60, and the temperature sensing tube 1 is located in the heat preservation chamber 610. A foaming layer is formed in the heat preservation chamber 610 through a foaming process.

[0076] In this embodiment, a heat preservation cavity 610 is defined between the cabinet body 40 and the inner liner 60, and a foaming layer is formed in the heat preservation cavity 610 through a foaming process.
