Description

Technical Field

[0001] The utility model relates to the technical field of vehicle-mounted refrigerators, and more specifically, it relates to a refrigerator with constant temperature control for the refrigerating chamber of a motorhome. Background Technique

[0002] A refrigerator with constant temperature control for the refrigerating chamber of a motorhome refers to a refrigeration device specifically designed for the use environment and requirements of a motorhome, which has specific functions and characteristics to adapt to mobile and bumpy conditions, while meeting the needs of fresh-keeping and freezing. Motorhome refrigerators usually use 12V DC power as the main power source and have better shock resistance and stability to ensure safety and reliability during driving.

[0003] With the continuous increase in the volume of motorhome refrigerators, traditional control methods cannot ensure a relatively balanced and stable temperature inside the box. The temperature difference inside the box can even exceed 8°C at most, which will affect the fresh-keeping and storage time of food.

[0004] Therefore, existing refrigerators with constant temperature control for the refrigerating chamber of a motorhome generally use an intelligent thermostat to achieve a relatively balanced and stable temperature inside the box. The intelligent thermostat generally uses multiple temperature sensors, a refrigeration system, a blower, a damper, a main control circuit board, and a supporting software algorithm to keep the inside of the refrigerator at a stable temperature. Specifically, the intelligent thermostat distributes temperature sensors evenly into the refrigerating chamber according to the size of the refrigerating chamber space. Through the main control circuit board, using the reference control logic built by the MCU, with the target temperature value set for the vehicle-mounted refrigerator and the actual temperature value inside the box as inputs in an offline manner, and using the algorithm of calculus, it performs real-time online comparison and simulation calculations on the data, and respectively controls the effective start and stop of the damper and the blower intelligently, and conveys the cold quantity in the refrigeration system into the refrigerating chamber to achieve the control of the temperature of the box body of the vehicle-mounted refrigerator. However, when the interval between the storage shelves of the motorhome refrigerator is too small, the fixed-height storage shelves cannot flexibly adapt to the storage needs of foods of different heights, which will force users to place some items horizontally or obliquely. This will cause the interval between the storage shelves to be too small, which will hinder the circulation of hot and cold air, resulting in a higher temperature in some areas and possibly being too cold in other areas. This will not only cause uneven food preservation, but also further waste space, and will also affect the uniform refrigeration effect of the refrigerator and is not conducive to maintaining the uniformity of the temperature inside the refrigerator.

[0005] Therefore, in order to solve the above technical problems, this application proposes a refrigerator with constant temperature control for the refrigerating chamber of a motorhome. Content of the Utility Model

[0009] One end of each placement board located in the sliding rail is provided with a sliding groove, and a limit plate is slidably installed in each sliding groove. Each limit plate can penetrate the corresponding placement board and slide on the corresponding placement board. One end of each limit plate located in the sliding groove is connected to the sliding groove through a spring A, and an anti-slip plate is installed at one end of each limit plate located in the sliding groove. The anti-slip plates are connected to each other through a connecting rod.

[0010] Preferably, a stability component is provided at the lower end of each placement board. The stability component includes a support plate. A plurality of support plates are symmetrically installed at the lower end of each placement board. A support block is mirror-installed on each support plate. Each vertical support block is set as a group. A rotating shaft is rotatably inserted into each group of support blocks. Both ends of each rotating shaft penetrate the corresponding support block respectively. A support leg is installed at one end of each rotating shaft located inside the support block. Each support leg is connected to the support plate through a spring B. A baffle is installed at one end of each group of support blocks away from the corresponding support plate, which is convenient for dispersing the weight of the items on the placement board, making the placement board more stable, and can also increase the load-bearing capacity of the placement board so that it can bear heavier objects, thereby facilitating users to store more or heavier items.

[0011] A plurality of stability grooves are equally spaced on both sides of the cold storage compartment and the freezer compartment. Each support leg can slide in the adjacent stability grooves, which is convenient for the support leg to be inserted into any adjacent stability groove.

[0012] Preferably, a door is rotatably installed at the corresponding position of the storage box for the cold storage compartment and the freezer compartment.

[0015] Preferably, each of the limiting plates can slide back and forth in a limiting groove provided in the adjacent slide rail, so that the limiting plate can be inserted into any adjacent limiting groove to fix the placement plate.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] 1. In the utility model, by setting the adjustment assembly on each placement plate, it is necessary to hold the connecting rods on both sides of the upper placement plate or the lower placement plate at the same time and move them closer to each other. When the connecting rod moves, it will move with the anti-slip plate, and when the anti-slip plate moves, it will move the limit plate into the slide groove. When the limit plate moves into the slide groove, the spring A will be compressed until all the limit plates are completely out of the limit grooves. Then the placement plate will be moved up or down. At this time, the placement plate will move up or down in the slide rail until the distance between the two placement plates is adjusted to a suitable position, and then Release the held connecting rod, and the spring A will no longer be compressed. At this time, the spring A will push the limit plate back into the limit groove through its resilience, so as to shape and fix the placement plate. At the same time, when the limit plate moves, it will restore the anti-slip plate and the connecting rod, thereby solving the problem in the background technology that the intervals between the shelves are too small, which will hinder the circulation of hot and cold air, resulting in higher temperatures in some areas and too cold in other areas, which will not only cause uneven food preservation, but also further waste space, and also affect the uniform cooling effect of the refrigerator, which is not conducive to maintaining the uniformity of the temperature inside the refrigerator.

[0018] 2. In the present utility model, through the stabilizing assembly provided at the lower end of each placement plate, when the placement plate is moved upward, all the support legs will also move upward together with the placement plate. When the support legs move upward, the support legs will compress the connected spring B, and the support legs will slowly move away from the stabilizing groove until the support legs disengage from the current stabilizing groove and move with the placement plate to the next stabilizing groove. At this time, spring B will no longer be compressed. Spring B will push the support legs into the stabilizing groove by its resilience and support the support legs. At the same time, the baffle will limit the position of the support legs. When the placement plate moves downward, the support legs cannot directly move with the placement plate due to the baffle and the inability to move directly downward. It is necessary to first hold the rotating shaft and rotate it. When the rotating shaft rotates, it will drive the support legs to rotate and disengage from the stabilizing groove. At the same time, the support legs will compress spring B until all the support legs completely disengage from the stabilizing groove. At this time, the placement plate will be moved downward until it reaches the appropriate position, and then the rotating shaft will be released. At this time, spring B will no longer be under pressure. Spring B will push the support legs into the stabilizing groove by its resilience. At the same time, the baffle will limit the position of the support legs, so as to achieve stable support for the placement plate, so as to achieve stable support for the placement plate through the support legs, which can effectively disperse the weight of the items on the placement plate, make the placement plate more stable, and can increase the load-bearing capacity of the placement plate, enabling it to bear heavier objects, thus facilitating users to store more or heavier items.

A rotating shaft 1103 is rotatably inserted into each set of support blocks 1102 for transmission. The two ends of each rotating shaft 1103 respectively penetrate through the corresponding support block 1102. A support leg 1104 is installed at one end of each rotating shaft 1103 inside the support block 1102 for achieving the function of supporting and stabilizing. A spring B1105 is connected between each support leg 1104 and the support board 1101, which is used to automatically push the support leg 1104 into the stabilizing groove 1107 and support the support leg 1104. A baffle 1106 is installed at one end of each set of support blocks 1102 away from the corresponding support board 1101 for facilitating the limitation of the support leg 1104. A plurality of stabilizing grooves 1107 are equidistantly opened on both sides of the refrigerating chamber 4 and the freezing chamber 5. Each support leg 1104 can slide in the mutually approaching stabilizing grooves, which is used to facilitate the insertion of the support leg 1104 into the stabilizing groove 1107 and then stabilize the placement board 9.

[0031] A box door 2 is rotatably installed at the corresponding positions of the storage box 1 for the refrigerating chamber 4 and the freezing chamber 5, which is used to facilitate opening and closing. The size of each box door 2 is larger than that of the corresponding refrigerating chamber 4 and freezing chamber 5, which is used to facilitate the full coverage of the refrigerating chamber 4 and the freezing chamber 5. A display screen 7 is installed on one of the box doors 2 for facilitating manual adjustment.

[0032] An intelligent temperature control component 6 is provided on the storage box 1. It is used to evenly distribute the temperature sensors 603 into the refrigerating chamber 4 and the freezing chamber 5 according to the sizes of the spaces of the refrigerating chamber 4 and the freezing chamber 5. Through the main control circuit board 601, using the reference control logic constructed by the MCU, taking the target temperature value set for the vehicle-mounted refrigerator and the actual temperature value inside the box as inputs in an offline manner, and using the calculus algorithm to compare and simulate the data in real time online, respectively to intelligently control the effective start and stop of the air damper 604 and the blower 602, and convey the cold quantity in the refrigeration system into the refrigerating chamber 4 and the freezing chamber 5 to achieve the control of the temperature of the box body of the vehicle-mounted refrigerator. The intelligent temperature control component 6 includes a main control circuit board 601.

[0033] Working principle: when the height of the food placed is higher than the distance between the two placement plates 9, first, you need to hold the connecting rods 1006 on both sides of the upper placement plate 9 or the lower placement plate 9 at the same time and move them closer to each other. When the connecting rods 1006 move, they will move with the anti-slip plate 1005. When the anti-slip plate 1005 moves, it will move the limiting plate 1003 into the slide groove 1002. When the limiting plate 1003 moves into the slide groove 1002, the spring A1004 will be compressed until all the limiting plates 1003 are completely separated from the limiting groove 1001. Then, the placement plate 9 will be moved upward or downward. At this time, the placement plate 9 will slide The control unit 1004 moves upward or downward in the rail 8 until the distance between the two placement plates 9 is adjusted to a suitable position, and then the holding connecting rod 1006 is released, and the spring A1004 will no longer be compressed. At this time, the spring A1004 will push the limiting plate 1003 back into the limiting groove 1001 through resilience, so as to fix the placement plate 9 in place. At the same time, when the limiting plate 1003 moves, it will bring the anti-slip plate 1005 and the connecting rod 1006 back to their original positions. When the placement plate 9 is moved upward, all the supporting legs 1104 will also move upward with the placement plate 9. When the supporting legs 1104 move upward, the supporting legs 1104 will press the connected springs B 1105 is compressed, and the support leg 1104 slowly moves away from the stable groove 1107 until the support leg 1104 leaves the stable groove 1107 and moves to the next stable groove 1107 with the placement plate 9. At this time, the spring B1105 will no longer be compressed. The spring B1105 will push the support leg 1104 into the stable groove 1107 through its resilience and support the support leg 1104. At the same time, the baffle 1106 will limit the support leg 1104. When the placement plate 9 moves downward, the support leg 1104 cannot move directly with the placement plate 9 because of the baffle 1106 and the reason that it cannot move directly downward. It is necessary to hold the rotating shaft 1103 first. And rotate its rotating shaft 1103. When the rotating shaft 1103 rotates, it will cause the supporting legs 1104 to rotate and disengage from the stable groove 1107. At the same time, the supporting legs 1104 will compress the springs B1105 until all the supporting legs 1104 are completely disengaged from the stable groove 1107. At this time, the placement plate 9 will be moved downward until it moves to a suitable position, and then the rotating shaft 1103 is released. At this time, the spring B1105 will no longer be under pressure, and the spring B1105 will push the supporting legs 1104 into the stable groove 1107 through rebound elasticity. At the same time, the baffle 1106 will limit the supporting legs 1104, so as to achieve stable support for the placement plate 9.
