[0021] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0022] Reference Appendix Figure 1-5 The present invention will be described using an evaporator connection device having four sets of positioning posts and snap-fit ​​components (each set including one positioning post and one snap-fit ​​component) as an example. The portable refrigerator 100 according to the present invention includes a cabinet 10, a cabinet cover 11, a first evaporator plate 12, and a second evaporator plate 13. The first evaporator plate 12 and the second evaporator plate 13 are substantially U-shaped. That is, the first evaporator plate 12 includes two first wall portions 121 and a second wall portion 122 connecting the two first wall portions, and the second evaporator plate 13 includes two first wall portions 131 and a second wall portion 132 connecting the two first wall portions. It also includes two evaporator connection devices 14 for connecting the ends of the two first wall portions 121 of the first evaporator plate 12 to the ends of the two first wall portions 131 of the second evaporator plate 13.

[0023] Specifically, each evaporator connection device 14 according to the present invention has a set of positioning posts 15 and snap-fit ​​components 16 located at the upper part and a set of positioning posts 15 and snap-fit ​​components 16 located at the lower part on its outer side wall, and a set of positioning posts 15 and snap-fit ​​components 16 located at the upper part and a set of positioning posts 15 and snap-fit ​​components 16 located at the lower part on its other side. Each of the two first wall portions 121 of the first evaporator plate 12 includes a first upper mounting plate portion 123 and a second lower mounting plate portion 124, wherein each first upper mounting plate portion 123 and the second lower mounting plate portion 124 is disposed outside the other portion of the first wall portion 121 of the first evaporator 12 and respectively includes a positioning hole 125 and a snap-fit ​​hole 126; each of the two first wall portions 131 of the second evaporator plate 13 includes a first upper mounting plate portion 133 and a second lower mounting plate portion 134, each first upper mounting plate portion 133 and the second lower mounting plate portion 134 is disposed outside the other portion of the first wall portion 131 of the second evaporator 13 and respectively includes a positioning hole 135 and a snap-fit ​​hole 136. When assembling the first evaporator plate 12 and the second evaporator plate 13, the upper positioning post 15 and the snap-fit ​​component 16 and the lower positioning post 15 and the snap-fit ​​component 16 on one side of the evaporator connecting device 14 are first engaged with one of the first evaporator plate 12 and the second evaporator plate 13 (for example, as shown in the attached diagram). Figure 4AThe positioning holes 135 and snap-fit ​​holes 136 of the first upper mounting plate portion and the second lower mounting plate portion of the second evaporator plate 13) are fitted together for assembly. Specifically, (because the length of the positioning post extension is greater than the length of the snap-fit ​​component extension) the upper positioning post 15 and the lower positioning post 15 will first pass through the positioning holes 135 of the first upper mounting plate portion and the second lower mounting plate portion. The movement of the positioning post in the positioning hole can play a directional and guiding role in the assembly. For example, the movement of the positioning post in the positioning hole can ensure that the direction of movement generated for assembly during the assembly process is basically correct. There is no deviation, ensuring that the snap-fit ​​component will not deviate during its movement and engagement with the snap-fit ​​hole, thus preventing snap-fit ​​failure. As the snap-fit ​​component engages with the snap-fit ​​hole, the connection assembly of the connecting device 14 with one of the first evaporator plate 12 and the second evaporator plate 13 (e.g., the second evaporator plate 13 as shown in Figure 4) is completed. Then, the upper positioning post 15 and snap-fit ​​component 16, as well as the lower positioning post 15 and snap-fit ​​component 16, of the other side of the evaporator connecting device 14 will engage with the other of the first evaporator plate 12 and the second evaporator plate 13 (e.g., the second evaporator plate 13 as shown in Figure 4). Figure 4B The positioning holes 135 and snap-fit ​​holes 136 of the first upper mounting plate portion and the second lower mounting plate portion of the first evaporator plate 12 shown are assembled in the same manner as the assembly method described above for the second evaporator plate 13, thereby finally completing the connection of the two evaporator plates. By employing an evaporator connecting device with a specific structure, namely an evaporator connecting device with a longer positioning post and snap-fit ​​component, and an evaporator plate with a specific mating structure, namely an evaporator plate with mating positioning holes and snap-fit ​​holes at the ends, this invention allows the connection of the two evaporators to be completed when assembling the two evaporator plates, through the mating of the positioning post and snap-fit ​​component of the evaporator connecting device with the positioning holes and snap-fit ​​holes of the evaporator plate respectively (i.e., the positioning post passes through the positioning hole and the snap-fit ​​component snaps into the snap-fit ​​hole, which basically only requires alignment and pressing operations), without the need for screws or rivets as in the prior art, thus making the connection between the evaporator plates faster, simpler, and more efficient.

[0024] Alternatively, in one embodiment of the present invention, a baffle portion 127 / 137 is arranged between the first upper mounting plate portion 123 / 133 and the second lower mounting plate portion 124 / 134 of each of the ends of the two first wall portions 121 of the first evaporator plate 12 and the ends of the two first wall portions 131 of the second evaporator plate 13. The baffle portion 127 / 137 is positioned inside the first upper mounting plate portion 123 / 133 and the second lower mounting plate portion 124 / 134 relative to them. The baffle portion located between the upper and lower mounting plate portions can, to a certain extent, prevent the foaming agent from leaking into the inner side of the evaporator plate after foaming, thereby reducing the risk of foaming agent leakage. When the first evaporator plate 12 and the second evaporator plate 13 are assembled via the evaporator connecting device 14, the baffle portion 127 / 137 can abut against the outer side wall of the evaporator connecting device 14, thereby preventing deformation of the baffle portion.

[0025] In one embodiment of the present invention, the evaporator connecting device 14 further includes a blocking frame portion 17 on its outer side wall. The blocking frame portion 17 includes two first frame wall portions 171 and a second frame wall portion 172 for connecting the two first frame wall portions 171. Each blocking frame portion 17 including the first frame wall portion 171 and the second frame wall portion 172 can surround each set of positioning posts 15 and snap-fit ​​members 16. For example, the surrounding configuration can be that the two first frame wall portions extend in the lateral direction and the second frame wall portion extends in the vertical direction, and the second frame wall portion is arranged closer to the middle position of the connecting device. When the first evaporator plate 12 and the second evaporator plate 13 are assembled via the evaporator connecting device 14, the blocking frame portion 17 can abut against the first upper mounting plate portion 123 / 133 and the second lower mounting plate portion 124 / 134. By arranging this blocking frame portion and having it abut against the first upper mounting plate portion 123 / 133 and the second lower mounting plate portion 124 / 134 after assembly, the foaming agent can be prevented from leaking into the inner side of the evaporator plate after foaming to a certain extent, thereby reducing the risk of foaming agent leakage.

[0026] Alternatively, in one embodiment of this invention, the portable refrigerator can be quickly and easily switched from a single-chamber to a dual-chamber configuration, and also from a single-chamber single-temperature operating mode to a dual-chamber dual-temperature operating mode. Specifically, a fixing rib 18 for mounting and fixing a removable partition plate 20 can be provided on the inner wall of the evaporator connecting device 14. The partition plate has a mounting groove, and through the cooperation of the mounting groove and the fixing rib, such as a sliding fit, the partition plate can be installed in place to divide the internal chamber into two sub-chambers. This allows the portable refrigerator to be switched from a single-chamber to a dual-chamber configuration. Furthermore, a detection device for checking whether the partition plate is inserted can be arranged at the fixing rib, for example, at the upper part of the fixing rib. This detection device can be connected to the control system of the portable refrigerator. When the partition plate is inserted into place through its mounting slot and engagement with the fixing rib, the detection device can detect that the partition plate is in place and send a signal to the refrigerator's control system, enabling it to determine that the partition plate is in place and divide the internal cavity into two sub-cavities. At this time, the control system can control the two evaporator plates to operate in different working modes so that the two sub-cavities of the portable refrigerator operate at different temperatures (for example, one sub-cavity serves as a refrigerator cavity, and the other sub-cavity serves as a freezer cavity). In an optional embodiment, in order to accommodate the cable of the detection device, an inverted U-shaped protrusion 19 can be provided on the outer wall of the evaporator connection device 14 at a position corresponding to the fixing rib 18. This inverted U-shaped protrusion can accommodate the cable of the detection device.

[0027] In one optional embodiment of this utility model, a reinforcing rib 20 can be arranged at the bottom of the positioning post 15 and / or the snap fastener 16. The reinforcing rib 20 can prevent the root of the positioning post / snap fastener from breaking under stress.

[0028] It should be understood that the examples described above are merely exemplary. In practice, different numbers of positioning posts and snap-fit ​​components, as well as corresponding positioning holes and snap-fit ​​holes, can be used. For example, at least two positioning posts and at least one snap-fit ​​component, along with at least two positioning holes and at least one snap-fit ​​hole, can be used.

[0029] In the description of the utility model, it should be understood that the description of including two first parts and connecting the two first parts is intended to indicate the shape of the component (not that the component is assembled from different parts); and the terms "top", "upper", "bottom", "lower", "inner", "outer", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation structure and operation, and therefore should not be construed as a limitation of the utility model.

[0030] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0031] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can combine, change, modify, replace and transform the above embodiments within the scope of the present invention.
