[0018] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more explicit definition of the scope of protection of the present invention.

[0019] The terms "comprising" and "having," and any variations thereof, used in this invention are intended to cover non-exclusive inclusion. References to "embodiment" herein mean that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0020] Combination Figure 1 and Figure 2As shown, this invention mainly relates to: a refrigeration device 1, including an inner liner 2, an outer shell 3, and insulation material (not shown) disposed between the inner liner 2 and the outer shell 3; wherein, the refrigeration device 1 further includes a compartment partition 4 adjacent to the inner liner 2 disposed within the outer shell 3, a fixing member 7 fixed to the compartment partition 4, a temperature sensing tube 8, and a flip-limiting member 6. A compressor compartment 40 for accommodating a compressor (not shown) is formed between the compartment partition 4 and the outer shell 3. The compartment partition 4 can be fixed to the outer shell 3 by welding. One end of the temperature sensing tube 8 is fixed to the outer wall of the inner liner 2, mainly used to detect the surface temperature of the evaporator (not shown) wrapped around the outer wall of the inner liner 2, and the other end extends through the compartment partition 4 into the compressor compartment 40.

[0021] Combination Figure 3 As shown, the bulkhead 4 of the engine compartment is provided with an installation port 5 that connects the inside and outside of the compressor compartment 40. One end of the temperature sensing tube 8 is fixed to the inner liner 2, and the other end extends into the compressor compartment 40 through the installation port 5. The direction of the installation port 5 is determined according to the installation direction of the inner liner 2 and the temperature sensing tube 8. A flip-up limiting member 6 is rotatably disposed on one side of the installation port 5. The flip-up limiting member 6 has a first state in which it flips open to allow the temperature sensing tube 8 to be installed. When the flip-up limiting member 6 is in the first state, when the inner liner 2 and the temperature sensing tube 8 are installed together, the other end of the temperature sensing tube 8 extends into the compressor compartment 40 through the installation port 5, realizing the initial installation of the temperature sensing tube 8. The flip-up limiting member 6 also has a second state in which it flips towards the installation port 5 and abuts against the temperature sensing tube 8. Preferably, the flip-up limiting member 6 can open or close the installation port 5, thereby achieving the purpose of fixing the installation of the temperature sensing tube 8.

[0022] In this invention, the refrigeration device 1 of this embodiment is a freezer. The outer shell 3 of the freezer has a receiving cavity 30 with a top opening. The inner liner 2 and the temperature sensing tube 8 are installed downward from the opening of the receiving cavity 30. That is, the inner liner 2 and the temperature sensing tube 8 are installed from top to bottom through the opening of the receiving cavity 30. During the installation of the inner liner 2 and the temperature sensing tube 8 from top to bottom, the temperature sensing tube 8 is fixed by flipping the flipping limiting member 6 towards the installation port 5.

[0023] Preferably, the cabin partition 4 includes an outer top wall 41 and an outer side wall 42 adjacent to the inner liner 2. The outer top wall 41 and the outer side wall 42 are vertically connected and integrally formed. The outer top wall 41, the outer side wall 42 and the outer shell 3 enclose a compressor compartment 40. The edges of the outer top wall 41 and the outer side wall 42 are welded to the inner shell 3 by means of a folded edge structure. The mounting port 5 penetrates the outer side wall 42 horizontally. During the installation of the inner liner 2 and the temperature sensing tube 8 from top to bottom, the other end of the temperature sensing tube 8 penetrates the outer side wall 42 horizontally through the mounting port 5, thereby achieving the purpose of the initial installation of the temperature sensing tube 8.

[0024] Furthermore, the installation port 5 is arranged in an inverted L-shape at the connection between the outer top wall 41 and the outer side wall 42, and includes a horizontal port 51 on the outer top wall 41 and a vertical port 52 on the outer side wall 42. When the temperature sensing tube 8 is installed from the opening direction of the receiving cavity 30, the other end of the temperature sensing tube 8 automatically falls into the horizontal port 51. As the temperature sensing tube 8 is installed from top to bottom, the other end of the temperature sensing tube 8 also penetrates into the vertical port 52, thereby completing the installation of the temperature sensing tube 8. It has the advantages of convenient installation and simple structure.

[0025] Combination Figure 4 and Figure 5 As shown, the flipping limiting member 6 includes a bent plate 61 that is rotatably disposed on one side of the mounting port 5 and cooperates with the mounting port 5.

[0026] Furthermore, the bending plate 61 sequentially includes a first plate 611 rotatably disposed on one side of the horizontal opening 51 and a second plate 612 perpendicular to the first plate 611. The first plate 611 can be rotatably connected to the second plate by setting a hinge shaft, or the first plate 611 can be set as a plastic rotating component to achieve the rotatable connection. When the flipping limiting component 6 is in the second state, the first plate 611 covers the horizontal opening 51, the second plate 612 covers the vertical opening 52, and the bottom of the second plate 612 forms an arc notch 613, which abuts against the upper part of the temperature sensing tube 8 to achieve the purpose of fixing the temperature sensing tube 8.

[0027] Furthermore, the flip-limiting component 6 also includes a flip plate 62 connected to the edge of the first plate 611. When the flip-limiting component 6 is in the first state, the flip plate 62 is located at the top of the first plate 611 and extends towards the inner liner 2. The flip plate 62 does not extend beyond the outer wall 42 of the cabin bulkhead 4 when it is in the first state. The part of the temperature sensing tube 8 that extends beyond the cabin bulkhead 4 overlaps with the flip plate 62. During the installation of the temperature sensing tube 8 from top to bottom, the other end of the temperature sensing tube 8 presses on the flip plate 62, causing the flip plate 62 to flip relative to the installation opening 5. This causes the first plate 611 to cover the horizontal opening 51, the second plate 612 to cover the vertical opening 52, and the arc notch 613 to abut against the upper part of the temperature sensing tube 8, thus achieving the purpose of fixing the temperature sensing tube 8 with the flip-limiting component 6. The entire installation and fixing process does not require additional work cycles and occurs naturally with the installation of the inner liner 2, which has the advantages of high work efficiency and convenient operation.

[0028] Preferably, the flip plate 62 is configured as a bent plate 61, including a flipping part 621 and a connecting part 623 that vertically connects the flipping part 621 and the first plate 611, which facilitates processing and increases the connection strength of the structure. The flipping part 621 has a first through hole 622 that extends vertically, which helps to reduce the weight of the flipping part 621, making it easier to flip, and also reduces the amount of material used.

[0029] In this embodiment, when the flipping limiting member 6 is in the second state, the flipping part 621 is located below the outer top wall 41. Preferably, the flipping part 621 is located parallel to the outer top wall 41 below. That is, when the flipping limiting member 6 is in the second state, the flipping part 621 is arranged parallel to the outer top wall 41 and extends towards the inner liner 2, making it easier for the flipping plate 62 to flip relative to the mounting opening 5.

[0030] Furthermore, the flipping limiting component 6 also includes a buckle 63 located at the vertical connection between the first plate 611 and the second plate 612. The buckle 63 has a second through hole 631 through it, which facilitates manual fine-tuning or adjustment of the installation position of the cabin bulkhead 4 by means of other tools.

[0031] Preferably, the fastener 7 is arranged in an inverted L-shape at the junction of the outer top wall 41 and the outer side wall 42, which can increase the connection strength with the cabin bulkhead 4 and facilitate processing. The fastener 7 has a through-opening mounting groove 71 and a guide extension 72 formed around the mounting groove 71. The fastener 7 is arranged near the side edge of the cabin bulkhead 4 so that part of the temperature sensing tube 8 is attached to the outer side wall 42 of the inner liner 2.

[0032] In an embodiment of the present invention, the other end of the temperature sensing tube 8 passes through the fixing member 7 and the cabin partition 4 in sequence, and the fixing member 7 and the cabin partition 4 together form an installation port 5. Preferably, the other end of the temperature sensing tube 8 first passes through the installation groove 71 and then through the third through hole 43 opened on the cabin partition 4. The installation groove 71 and the third through hole 43 together form the installation port 5, thereby completing the purpose of the other end of the temperature sensing tube 8 extending into the compressor compartment 40. Preferably, the installation groove 71 includes a first groove segment 711, which is inverted L-shaped and continuously arranged at the connection between the outer top wall 41 and the outer side wall 42, and a second groove segment 712, which is arc-shaped and adapted to the temperature sensing tube 8.

[0033] Furthermore, the temperature sensing tube 8 includes a temperature sensing tube body 81 and a tube plug 82 disposed on the outer wall of the temperature sensing tube body 81. The outer peripheral wall of the tube plug 82 has an annular groove 821, and the bottom of the guide extension 72 extends upward to form a protruding plate 720 that can be inserted into the groove 821. As the temperature sensing tube 8 is installed from top to bottom, the other end of the temperature sensing tube 8 also extends into the vertical opening 52. When the protruding plate 720 is inserted into the groove 821, the temperature sensing tube 8 is positioned and installed, thereby achieving the relative positioning and installation of the cabin bulkhead 4 and the inner liner 2. This has the advantage of a simple positioning and installation method.

[0034] Preferably, the guide extension 72 includes, from top to bottom, an L-shaped guide section 721 and an arc section 722. The guide section 721 is correspondingly disposed with the first groove section 711, and the arc section 722 is correspondingly disposed with the second groove section 712. The spacing between the guide sections 721 is greater than the outer diameter of the pipe plug 82. The arc section 722 is adapted to the contact portion with the outer wall of the pipe plug 82. The arc section 722 and the arc notch 613 are combined vertically to form a limiting space for fixing the pipe plug 82.

[0035] Preferably, the guide extension 72 further includes a boss 723 located between the guide section 721 and the arc section 722 and extending inward. The boss 723 is configured to dock with the bending plate 61. When the flip plate 62 flips relative to the mounting port 5, when the bottom of the bending plate 61 contacts the boss 723, the arc notch 613 abuts against the upper part of the temperature sensing tube 8.

[0036] The installation process of this invention is as follows: First, one end of the temperature sensing tube 8 is fixed to the inner liner 2. The inner liner 2 and the temperature sensing tube 8 are installed from top to bottom through the opening of the receiving cavity 30. During the installation of the temperature sensing tube 8 from top to bottom, the other end of the temperature sensing tube 8 will press on the flip plate 62, causing the flip plate 62 to flip relative to the installation port 5. The other end of the temperature sensing tube 8 will automatically fall into the horizontal port 51, completing the initial installation of the temperature sensing tube 8. As the temperature sensing tube 8 is installed from top to bottom, the other end of the temperature sensing tube 8 will also penetrate into the vertical port 52. When the protruding plate 720 is inserted into the groove 821, the positioning installation of the temperature sensing tube 8 is also achieved. When the bending plate 61 is connected to the boss part 723, the first plate 611 covers the horizontal port 51, the second plate 612 covers the vertical port 52, and the arc notch 613 abuts against the upper part of the temperature sensing tube 8, thereby achieving the purpose of fixing the temperature sensing tube 8.

[0037] Compared with the prior art, the refrigeration equipment 1 provided by the present invention is fixed to the inner liner 2 by one end of the temperature sensing tube 8, and the inner liner 2 and the temperature sensing tube 8 are pre-installed together. One end of the temperature sensing tube 8 extends into the compressor chamber 40 through the installation port 5 to achieve the pre-positioning of the temperature sensing tube 8. Then, the temperature sensing tube 8 is fixedly installed by flipping the limiting member 6 to the first and second states. The operation is simple and easy to apply on a large scale in actual production. It has the advantages of easy installation and simple fixing method.

[0038] The terms "installation," "connection," and "linking" should be interpreted broadly. For example, "linking" can mean a fixed connection, a detachable connection, or an integral connection; it can mean a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of these terms in this invention based on the specific circumstances.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of the present invention.
