Description

Technical Field

[0001] This utility model relates to the field of refrigeration electrical technology, and in particular to a dual-temperature dual-control refrigeration structure and a vehicle refrigerator. Background Technology

[0002] Dual-temperature, dual-control car refrigerators are advanced in-vehicle refrigeration devices with two independent temperature control zones, simultaneously meeting both freezing and refrigeration needs. This design offers users greater flexibility, enabling them to store different types of food and beverages at the same time, satisfying diverse storage requirements. However, current dual-temperature, dual-control car refrigerators still have some design and performance issues.

[0003] Most existing dual-temperature, dual-control car refrigerators use two capillary tubes to cool the evaporators of two separate compartments, and the cooling systems of the two compartments are not interconnected (see attached). Figure 1 (As shown). While this design enables independent temperature control, it performs poorly in terms of energy consumption. Energy consumption tests in Europe and North America have consistently shown that existing dual-temperature, dual-control refrigeration structures have high energy consumption. This not only increases user costs but also fails to meet increasingly stringent energy efficiency standards and environmental requirements. The high energy consumption stems from the inefficiency of the refrigeration system, which cannot flexibly adjust the cooling capacity according to actual needs, leading to energy waste.

[0004] To address the aforementioned issues, existing technologies urgently need improvement. Utility Model Content

[0005] The purpose of this invention is to provide a dual-temperature, dual-control cooling structure and a vehicle-mounted refrigerator, which has the advantages of making full use of refrigeration resources for flexible allocation and improving energy efficiency.

[0006] In a first aspect, this utility model provides a dual-temperature, dual-control cooling structure, comprising:

[0007] The container is equipped with a cavity.

[0008] A partition plate is detachably disposed within the receiving cavity, and the partition plate can divide the receiving cavity into a first receiving cavity and a second receiving cavity;

[0009] The first evaporator tube is located on the side of the housing that faces away from the first receiving cavity;

[0010] The first capillary tube is located at the input end of the first evaporator tube;

[0011] The second evaporator tube is located on the side of the housing that faces away from the second housing cavity;

[0012] The connection tee includes a first inlet, a second inlet, and a first outlet. The first inlet is connected to the output end of the first evaporator tube, and the first outlet is connected to the input end of the second evaporator tube.

[0013] The second capillary is located at the second inlet.

[0014] This utility model provides a dual-temperature, dual-control refrigeration structure. By connecting the first and second evaporator tubes with a connecting tee, the refrigerant delivered by the first capillary tube can flow into the second evaporator tube, and vice versa. This allows for flexible allocation of refrigeration resources, improving energy efficiency. Furthermore, the partition is removable. When the partition is removed, single-temperature, single-compartment refrigeration is possible; when the partition is inserted, dual-temperature, dual-compartment refrigeration is possible, enhancing the flexibility of the vehicle refrigerator.

[0015] Furthermore, the housing is provided with one of a first snap-fit ​​block and a first snap-fit ​​groove, and the partition is provided with the other of a first snap-fit ​​block and a first snap-fit ​​groove, wherein the first snap-fit ​​block can be inserted into the first snap-fit ​​groove.

[0016] By adopting the above technical solution, by providing a first snap-fit ​​block or a first snap-fit ​​groove on the receiving box, and providing a first snap-fit ​​groove or a first snap-fit ​​block that cooperates with it on the middle partition, the middle partition can be firmly inserted into the receiving box, thereby dividing the receiving cavity into two independent areas.

[0017] Furthermore, there are two of each of the first latching blocks and the first latching slots. One of the two first latching blocks and the first latching slots is respectively located on opposite sides of the receiving box, and the other of the two first latching blocks and the first latching slots is respectively located on opposite sides of the middle partition.

[0018] Furthermore, it also includes a return pipe, which is located at the output end of the second evaporator tube, and the return pipe is used to recover the refrigerant output from the first evaporator tube and the second evaporator tube.

[0019] Furthermore, the receiving box includes a base, a first C-shaped sidewall, and a second C-shaped sidewall. The first C-shaped sidewall and the second C-shaped sidewall are disposed on the base, and the base, the first C-shaped sidewall, and the second C-shaped sidewall enclose the receiving cavity.

[0020] Furthermore, the base is provided with a magnetic switch on the side facing the cavity, and the magnetic switch can be triggered by the partition plate to control the second capillary tube to deliver refrigerant to the second evaporator tube.

[0021] By adopting the above technical solution, a magnetic switch is set on the side of the base facing the cavity. When the middle partition is inserted into the cavity, the magnetic switch is triggered, thereby controlling the second capillary tube to deliver refrigerant to the second evaporator tube. The vehicle refrigerator switches from single-box single-temperature cooling to dual-box dual-temperature cooling. The vehicle refrigerator can flexibly adjust the delivery of refrigerant under different working conditions, reducing unnecessary energy consumption and improving the overall energy efficiency.

[0022] Furthermore, the base is provided with a second snap-fit ​​groove on the side facing the cavity, the partition plate can be inserted into the second snap-fit ​​groove, and the magnetic switch is located in the second snap-fit ​​groove.

[0023] Using the above technical solution, the base is also provided with a second slot on the side facing the cavity. The partition can be inserted into the second slot, and the magnetic switch is located in the second slot. This design can not only effectively fix the partition, but also ensure that the magnetic switch can be triggered after the partition is inserted.

[0024] Furthermore, the housing also includes a first side column and a second side column, which are located on opposite sides of the base. The first side column has a first side groove at its opposite ends, and the second side column has a second side groove at its opposite ends. The opposite ends of the first C-shaped side wall are respectively inserted into the first side groove and the second side groove on one side, and the opposite ends of the second C-shaped side wall are respectively inserted into the first side groove and the second side groove on the other side.

[0025] By adopting the above technical solution and adding side columns and side grooves to the housing, the stability and sealing of the entire structure are enhanced, thereby effectively reducing cold air leakage, improving refrigeration efficiency, and reducing energy consumption.

[0026] Furthermore, the first side post is also provided with a plurality of first locking blocks, which are spaced apart in the first side groove. The second side post is also provided with a plurality of second locking blocks, which are spaced apart in the second side groove. The first C-shaped side wall is provided with a plurality of first locking slots, and the second C-shaped side wall is provided with a plurality of second locking slots. The first locking blocks at opposite ends of the first side post are respectively inserted into the first locking slot and the second locking slot on one side. The second locking blocks at opposite ends of the second side post are respectively inserted into the first locking slot and the second locking slot on one side.

[0027] By adopting the above technical solution, a stable connection between the components is achieved by setting blocks and slots on the side pillars and side walls, which helps to improve the stability and reliability of the overall structure.

[0028] Secondly, the present invention provides a vehicle refrigerator, including any of the above-mentioned dual-temperature dual-control cooling structures.

[0029] As can be seen from the above, the dual-temperature, dual-control refrigeration structure provided by this utility model connects the first evaporator tube and the second evaporator tube through a connecting tee. The refrigerant delivered by the first capillary tube can flow into the second evaporator tube via the first evaporator tube, and the refrigerant delivered by the second capillary tube can flow into the second evaporator tube, achieving flexible allocation of refrigeration resources and helping to improve energy efficiency. Furthermore, the partition is detachable; when the partition is removed, single-temperature, single-chamber refrigeration is possible; when the partition is inserted, dual-temperature, dual-chamber refrigeration is possible, further enhancing the flexibility of the vehicle refrigerator.

Detailed Implementation

[0037] 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 throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0038] The following disclosure provides many different embodiments or examples for implementing various structures of the present invention. To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or reference letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0039] Dual-temperature, dual-control vehicle refrigerators are advanced in-vehicle refrigeration devices with two independent temperature control zones, simultaneously meeting freezing and refrigeration needs. However, most current dual-temperature, dual-control vehicle refrigerators use two capillary tubes to cool the evaporators of two separate compartments, with the cooling systems of the two compartments not interconnected. Therefore, in European and North American energy consumption tests, existing dual-temperature, dual-control refrigeration structures generally exhibit high energy consumption.

[0040] In order to overcome the problem of high energy consumption in the existing technology, the dual-temperature dual-control refrigeration structure disclosed in this utility model is mainly used in vehicle refrigerators. It has the advantages of making full use of refrigeration resources for flexible allocation and improving energy utilization efficiency.

[0041] Reference Appendix Figure 2 Appendix Figure 3In one embodiment, the dual-temperature dual-control cooling structure includes a housing 100, a partition 200, a first evaporator tube 300, a first capillary tube 400, a second evaporator tube 500, a connecting tee 600, and a second capillary tube 700.

[0042] Specifically, the set temperature of the second receiving cavity 112 is lower than the set temperature of the first receiving cavity 111. During refrigeration, the second capillary tube 700 can be controlled to supply refrigerant to the second evaporator tube 500 for refrigeration. When the temperature of the second receiving cavity 112 reaches the set temperature, the first capillary tube 400 can be controlled to supply refrigerant to the first evaporator tube 300 for refrigeration. The refrigerant output from the first evaporator tube 300 can also enter the second evaporator tube 500 to supplement the refrigeration of the second receiving cavity 112. This helps to reduce the on / off ratio, realize the full utilization of refrigeration resources, and improve energy efficiency.

[0043] As can be seen from the above, the dual-temperature, dual-control refrigeration structure provided by this utility model connects the first evaporator tube 300 and the second evaporator tube 500 through a connecting tee 600. The refrigerant delivered by the first capillary tube 400 can flow into the second evaporator tube 500 via the first evaporator tube 300, and the refrigerant delivered by the second capillary tube 700 can flow into the second evaporator tube 500, achieving flexible allocation of refrigeration resources and helping to improve energy efficiency.
