[0034] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0035] A refrigerator that is convenient for distributing cold capacity, the structure of which can be Figure 1-Figure 9 Schematic diagram. In this embodiment, the refrigerator for facilitating cold distribution includes a cabinet 1 and a plurality of loading trays, wherein a receiving cavity 11 is provided inside the cabinet 1, and the loading tray is detachably arranged inside the receiving cavity 11, and each loading tray includes a tray body 2 and an adjustment inner core 3, and a guide cavity 21 is provided inside the tray body 2, and the position of the adjustment inner core 3 is adjustable inside the guide cavity 21. In addition, an openable cabinet door may be provided on the cabinet 1, so that the user can open or close the receiving cavity 11 by opening and closing the cabinet door. When in use, the user can place the items to be frozen on the loading tray for storage, and the built-in refrigeration system of the cabinet 1 can generate cold through the circulation of the refrigerant, and transport the cold to the loading tray with gas as the cold medium, so as to realize the low-temperature storage or freezing of the items, and the user can also adjust the position of the adjustment inner core 3 according to the items in different areas on the loading tray, so as to form a difference in cold distribution between different areas on the loading tray.

[0036] In order to facilitate the entry of the cold air into the guide cavity 21, the present embodiment is provided with a cold air inflow channel and a cold air outflow channel in the side wall of the cabinet 1, and an air inlet pipe 41 and an air outlet pipe 42 are provided in parallel in the guide cavity 21, wherein the air inlet pipe 41 is connected with the cold air inflow channel, and a plurality of air inlet holes 411 are provided on the air inlet pipe 41, and the air outlet pipe 42 is connected with the cold air outflow channel, and a plurality of air outlet holes 421 are provided on the air outlet pipe 42. When in use, the cold air will enter the air inlet pipe 41 along the cold air inflow channel, and flow into the guide cavity 21 through the air inlet holes 411, thereby exchanging heat with the tray body 2, reducing the temperature of the tray body 2, and then the gas in the guide cavity 21 will enter the air outlet pipe 42 through the air outlet holes 421, and finally enter the cold air outflow channel.

[0037] Optionally, in order to achieve the connection between the air inlet pipe 41 and the cold air inflow channel, and to achieve the connection between the air outlet pipe 42 and the cold air outflow channel, as shown in FIG. Figure 2 As shown, the inner side wall of the receiving cavity 11 may be provided with a plurality of inflow holes 12 and a plurality of outflow holes 13, and the inflow holes 12 are connected to the cold air inflow channel, and the outflow holes 13 are connected to the cold air outflow channel. Correspondingly, an air inlet pipe and an air outlet pipe may be provided on the side wall of the tray body 2, wherein the air inlet pipe is connected to the air inlet pipe 41, and the air outlet pipe is connected to the air outlet pipe 42. When the user loads the loading tray into the receiving cavity 11, the air inlet pipe should be inserted into the inflow hole 12, and the air outlet pipe should be inserted into the outflow hole 13, so as to realize the smooth circulation of gas.

[0038] In addition, in order to improve the air tightness near the air inlet and outlet pipes, such as Figure 3 As shown, a sealing sleeve 6 should be provided on both the air inlet pipe and the air outlet pipe, so that the sealing sleeve 6 can be used to seal the joint gap to prevent gas from flowing outward along the joint gap.

[0039] As an optional implementation of the present embodiment, in order to reduce the difficulty of assembling the cargo tray and the cabinet 1, a guide strip 22 may be further provided on the side wall of the tray body 2, and a guide groove 14 for accommodating the guide strip 22 should be provided on the inner side wall of the accommodating cavity 11, so that the disassembly and assembly process of the cargo tray can be guided by the cooperation of the guide strip 22 and the guide groove 14, thereby improving the user's operating convenience.

[0040] Figure 5A schematic diagram of the adjusting inner core 3 is shown in the figure. In order to form a difference in cold distribution between different areas on the loading tray in the present device, a first accommodating hole 31 for accommodating the air inlet pipe 41 and a second accommodating hole 32 for accommodating the air outlet pipe 42 should be provided on the adjusting inner core 3, and two isolation plates 33 perpendicular to the air inlet pipe 41 are provided on the top surface of the adjusting inner core 3, a guide channel 331 is formed between the two isolation plates 33, and an air inlet cutout 34 connected to the first accommodating hole 31 and an air outlet cutout 35 connected to the second accommodating hole 32 are also provided on the bottom surface of the guide channel 331.

[0041] When the regulating inner core 3 is loaded into the flow guiding cavity 21, the top surfaces of the two isolation plates 33 will contact the top inner wall of the flow guiding cavity 21, so the flow guiding channel 331 will be isolated from other areas inside the flow guiding cavity 21. The gas entering the cargo tray through the air inlet pipe 41 will be divided into two parts, one part of the gas will enter the flow guiding channel 331 through the air inlet cutout 34, and flow back to the inside of the air outlet pipe 42 through the air outlet cutout 35, thereby exchanging heat with the area of ​​the tray body 2 located directly above the regulating inner core 3, and the other part of the gas will enter the inside of the flow guiding cavity 21 along the air inlet hole 411 not covered by the regulating inner core 3, and flow back to the inside of the air outlet pipe 42 along the air outlet hole 421 not covered by the regulating inner core 3, thereby exchanging heat with other areas on the tray body 2.

[0042] As another optional implementation of this embodiment, in order to reduce the difficulty of assembling the tray body 2 and the adjustment inner core 3, as shown in FIG. Figure 4 As shown, the side wall of the tray body 2 may be provided with a mounting cutout 24 connected to the guide cavity 21, and a detachable mounting baffle 241 may be provided on the mounting cutout 24. During assembly, the user should first remove the mounting baffle 241 to facilitate the installation of the adjustment inner core 3 into the guide cavity 21 along the mounting cutout 24, and then install the mounting baffle 241 to block the mounting cutout 24 through the mounting baffle 241 to prevent the gas inside the guide cavity 21 from leaking out.

[0043] Figure 7-Figure 9 All are cross-sectional views of the loading tray. Figure 8 As shown, when the gas flows inside the guide cavity 21, the gas capacity in the guide cavity 21 is large, and the probability of the gas contacting the top inner wall of the guide cavity 21 is low. Therefore, when the gas carrying cold energy enters the guide cavity 21, not only will the flow rate of the gas slow down, but the gas that has completed the heat exchange work will not be able to leave the guide cavity 21 in time, which will cause the temperature difference between the gas inside the guide cavity 21 and the top inner wall of the guide cavity 21 to become smaller, which is not conducive to the rapid transfer of cold energy in the gas to the inside of the tray body 2. Figure 7As shown, since the existence of the regulating inner core 3 will occupy the internal space of the guide cavity 21, when the gas flows inside the guide channel 331, the gas capacity in the guide channel 331 is small, and the gas has a higher probability of contacting the top inner wall of the guide cavity 21. When the gas flow and pressure entering the loading tray remain constant, since the gas capacity in the guide channel 331 is small, the gas enters and exits the guide channel 331 at a faster speed, so that the top inner wall of the guide channel 331 and the flowing gas always maintain a sufficient temperature difference, and the gas has a higher probability of contacting the top inner wall of the guide cavity 21 inside the guide channel 331, so that the cold energy can be transferred well, so that the area of ​​the tray body 2 located directly above the regulating inner core 3 can obtain more cold energy, thereby achieving the purpose of improving the freezing efficiency of the items in this area. When using it, the user can also change the position of the regulating inner core 3 according to actual needs, so that the regulating inner core 3 moves below the items that need to be quickly frozen, so as to reasonably distribute the cold energy on the loading tray.

[0044] Optionally, in order to further increase the flow velocity of the gas in the guide channel 331, a guide plate 5 detachable from the adjustment inner core 3 by bolts may be provided on the air inlet 34 in this embodiment. Figure 4 and Figure 5 As shown, the guide plate 5 is provided with a plurality of guide holes 51, and the aperture of the air inlet hole 411 is equal to the aperture of the air outlet hole 421, and the aperture of the guide hole 51 is smaller than the aperture of the air inlet hole 411. When the gas flows into the guide channel 331, due to the diameter difference between the air inlet hole 411 and the guide hole 51, the gas is accelerated after passing through the guide hole 51, thereby further increasing the gas flow rate inside the guide channel 331.

[0045] In addition, in order to improve the heat exchange effect between the gas and the top inner wall of the guide cavity 21, a plurality of heat exchange grooves 211 may be provided on the top inner wall of the guide cavity 21, and the length direction of each heat exchange groove 211 should be parallel to the air inlet pipe 41. By providing a plurality of heat exchange grooves 211, the available heat exchange area of ​​the top inner wall of the guide cavity 21 can be increased, so that a better heat exchange effect can be obtained after the gas carrying cold enters the interior of the cargo tray. Accordingly, in order to prevent the existence of the heat exchange grooves 211 from causing the gas inside the guide channel 331 to flow outward, a plurality of blocking protrusions 332 should be provided on the top surface of the isolation plate 33. After the adjustment inner core 3 is loaded into the interior of the guide cavity 21, the plurality of blocking protrusions 332 are inserted into the plurality of heat exchange grooves 211 one by one, thereby blocking the heat exchange grooves 211.

[0046] In order to facilitate the user to observe the actual position of the adjustment inner core 3 during actual use, and to facilitate the movement of the adjustment inner core 3, as shown in FIG. Figure 4 and Figure 6As shown, an operation cutout 23 may be further provided on the top surface of the tray body 2, a detachable transparent protective cover 7 is provided on the operation cutout 23, and a detachable operation protrusion 36 is provided on the top surface of the adjustment inner core 3. After the adjustment inner core 3 is loaded into the diversion cavity 21, the user can install the bottom end of the operation protrusion 36 on the top surface of the adjustment inner core 3, and insert the top end of the operation protrusion 36 into the operation cutout 23, so that the user can apply a force to the adjustment inner core 3 through the operation protrusion 36 to drive the adjustment inner core 3 to move. Accordingly, after completing the position adjustment of the adjustment inner core 3, the user should install the transparent protective cover 7 on the operation cutout 23. At this time, the transparent protective cover 7 can not only block the operation cutout 23 to prevent the gas inside the diversion channel 331 from leaking, but also facilitate the user to observe the operation protrusion 36, and then judge the position of the adjustment inner core 3.

[0047] In addition, in order to improve the airtightness near the transparent protective cover 7 , a sealing ring 71 may be provided on the transparent protective cover 7 , so that the joint gap around the transparent protective cover 7 can be sealed with the help of the sealing ring 71 .

[0048] The effects of the above scheme are described below:

[0049] The present embodiment provides a refrigerator that is convenient for cold distribution. It can form a relatively independent guide channel inside the guide cavity by adjusting the inner core, and make the gas carrying cold obtain a higher flow velocity in the guide channel, so that the area where the tray body is located above the adjusting inner core obtains more cold distribution, and accelerates the freezing efficiency of the items in this area. When in use, the present device can also change the position of the adjusting inner core according to actual needs, so as to flexibly adjust the cold distribution between different areas on the cargo tray. Secondly, the present device can improve the heat exchange effect between the gas and the inner wall at the top of the guide cavity through the heat exchange groove, and can further improve the gas flow rate in the guide channel through the guide plate. In addition, the present device can also reduce the difficulty of assembling and adjusting the position of the adjusting inner core by setting the installation incision and the operation incision.

[0050] It should be additionally explained that the refrigeration system described in this embodiment is a mature existing technology. It is also a common practice for technical personnel in this field to generate cold through a refrigeration system and use gas as a cooling medium to transport cold. Therefore, the specific structure and related working principles for realizing the above functions will not be repeated in this article.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
