Description

A type of refrigerator

Technical Field

This application relates to the field of refrigeration equipment technology, and more particularly to a refrigerator.

Background Technology

Medical refrigerators are mainly used for the refrigeration, preservation, and transportation of medicines, reagents, vaccines, blood, etc. Existing refrigerators include those with water tanks, some of which completely enclose the storage space (such as the structure disclosed in CN104976843B), resulting in good insulation. However, this structure has low space utilization. Other refrigerators use heat pipes installed outside the water tank, with a heat-conducting plate connected below the heat pipes (such as the structure disclosed in CN202158721U), which can achieve uniform temperature within the storage space. However, this structure is overly complex due to the heat pipes and heat-conducting plate method, making assembly cumbersome and the heat pipes difficult to maintain. Furthermore, the heat-conducting plate also reduces the volume of the storage space.

Summary of the Invention

To address the aforementioned technical issues, this application provides a refrigerator that eliminates the need for a water tank to completely enclose the cold storage chamber, thereby increasing the volume of the cold storage chamber. Furthermore, it eliminates the need for heat pipes and heat-conducting plates, simplifying the structure and assembly process of the refrigerator.

This application provides a refrigerator, including an inner liner and a metal partition disposed within the inner liner. The metal partition divides the inner liner into a cold storage chamber and a refrigeration chamber. The cold storage chamber uses the metal partition as its front sidewall, and the refrigeration chamber uses the metal partition as its rear sidewall. The cold storage chamber includes a top cold storage section located above the refrigeration chamber and a lateral cold storage section extending downward from the top cold storage section and located on one side of the refrigeration chamber. An evaporator is disposed within the top cold storage section, and the evaporator is configured to cool the refrigerant within the top cold storage section and the lateral cold storage section.

This application uses a metal partition to divide the inner liner into a cold storage chamber and a refrigeration chamber. The cold storage chamber includes a top cold storage section and a side cold storage section. Compared to the structure of a water tank that encloses the storage space, this application only needs to set a top cold storage section at the top of the refrigeration chamber and a side cold storage section on one side of the refrigeration chamber to meet the refrigeration requirements of the items in the refrigeration chamber. No cold storage structure is set in other parts of the refrigeration chamber, thus allowing the space in other parts of the refrigeration chamber to be used to increase the volume of the refrigeration chamber. Moreover, this application does not require the installation of heat pipes and heat conduction plates, simplifying the structure and assembly process of the refrigerator, and the space that would be used for heat conduction plates can be used to increase the volume of the refrigeration chamber.

As a preferred technical solution, the metal partition includes a first plate extending downward from the top wall of the inner liner, a second plate extending from the first plate to the rear side wall of the inner liner, and a third plate extending from the second plate to the bottom wall of the inner liner. The top cooling storage section is formed between the first plate, the second plate, and the wall of the inner liner, and the lateral cooling storage section is formed between the third plate and the wall of the inner liner.

As a preferred technical solution, the third plate has a first insulation layer on the side facing the refrigeration cavity;

And/or, the second plate is provided with a second insulation layer on the side facing the refrigeration cavity.

As a preferred technical solution, the inner liner has an annular groove on its peripheral sidewall, and the refrigerator also includes a sealing gasket surrounding the metal partition, the metal partition being interference-sealed and fixed in the annular groove by the sealing gasket;

Alternatively, the inner liner may have an annular groove on its peripheral sidewall, into which the metal partition is inserted, and the connection between the metal partition and the annular groove is sealed with sealant.

As a preferred technical solution, the edge of the metal partition is provided with a connecting part along the circumferential direction. The connecting part passes through the peripheral sidewall of the inner liner and is bent. The connecting part is provided with multiple holes, and fasteners pass through the holes and are fixed to the peripheral sidewall.

As a preferred technical solution, the ratio of the depth of the lateral cold storage section to the depth of the cold storage section in the direction from the refrigeration cavity to the lateral cold storage section is in the range of 1:20-1:10.

As a preferred technical solution, the refrigerator also includes an outer shell, the inner liner is placed inside the outer shell, and an insulation layer is formed between the outer shell and the inner liner through a foaming process.

As a preferred technical solution, the outer casing includes a housing and a door, with one end of the housing having an opening, and the door being able to open or close the opening.

As a preferred technical solution, the refrigerator also includes a compressor and a condenser, and the compressor, the condenser and the evaporator form a refrigeration system.

As a preferred technical solution, a number of trays located in the refrigeration chamber are spaced apart on one side of the metal partition, and the cold energy in the cold storage chamber can be transferred to the trays.

Detailed Implementation

To better understand the above-mentioned objectives, features, and advantages of this application, the solution of this application will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

Many specific details are set forth in the following description in order to provide a full understanding of this application, but this application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of this application, and not all embodiments.

This application provides a device with a refrigeration function, which can be a vehicle refrigerator, a small household refrigerator, or a refrigerator box, such as a medical refrigerator box or a home medical box.

As shown in Figures 1 and 2, the refrigerator of this embodiment includes an inner liner 1, an outer shell 2, and a refrigeration system. The inner liner 1 is installed inside the outer shell 2 and is preferably made of metal. A metal partition 3 is also provided inside the inner liner 1, which divides the inner liner 1 into a cold storage chamber 11 and a refrigeration chamber 12. The refrigeration chamber 12 is used to place items. The cold storage chamber 11 is provided with a cold storage agent and an evaporator 41 of the refrigeration system. The cold storage agent is cooled by the evaporator 41, and the cold storage agent can release cold energy into the refrigeration chamber 12, thereby refrigerating the items in the refrigeration chamber 12.

In this embodiment, the inner liner 1 is divided into a cold storage chamber 11 and a refrigeration chamber 12 by a metal partition 3. This eliminates the need for an additional water tank and structures such as heat pipes or heat-conducting plates connected to the water tank, simplifying the structure and assembly process of the refrigerator. Furthermore, the metal partition 3 fully utilizes the internal space of the inner liner 1, maximizing the volume of the refrigeration chamber 12. Additionally, by forming the cold storage chamber 11, when the power supply to the refrigerator is interrupted, the refrigerant within the cold storage chamber 11 can release its cooling capacity to maintain a constant temperature environment within the refrigeration chamber 12.

Furthermore, in this embodiment, the metal partition 3 forms the front sidewall of the cold storage chamber 11 and the rear sidewall of the cold storage chamber 12. In addition, the metal partition 3 has better cold energy transfer performance, so the cold energy transfer between the cold storage chamber 11 and the cold storage chamber 12 is directly from the cold storage agent in the cold storage chamber 11 to the metal partition 3 and then to the cold storage chamber 12. That is, the cold energy in the cold storage chamber 11 can be directly transferred to the cold storage chamber 12 through the metal partition 3, thereby improving the cold energy conduction efficiency.

In this embodiment, as shown in Figure 1, the metal partition 3 can adopt a "Z"-shaped structure. The cold storage cavity 11 formed between the metal partition 3 and the wall of the inner liner 1 includes a top cold storage section 111 located above the refrigeration cavity 12 and a lateral cold storage section 112 extending downwards from the top cold storage section 111 and located on one side of the refrigeration cavity 12. That is, the cold storage cavity 11 in this embodiment is simultaneously formed at the top and side (specifically the rear side) of the refrigeration cavity 12. Through this structure, the refrigerant in the cold storage cavity 11 can simultaneously release cold energy to both the upper and side ends of the cold storage cavity 11, making the temperature uniform at all locations within the cold storage cavity 11 and ensuring that the items are within the required temperature range at all angles. Furthermore, compared to the structure of a water tank enclosing the storage space in the prior art, no cold storage structure is provided in other locations of the refrigeration cavity 12 (such as the front, left and right sides, or bottom), thus allowing the space in other locations of the refrigeration cavity 12 to be used to increase the volume of the refrigeration cavity 12. On the other hand, the above-mentioned structure of this application does not require the installation of heat pipes and heat conduction plates, which simplifies the structure and assembly process of the refrigerator. Moreover, the space required for installing the heat conduction plate can be used to increase the refrigerator cavity 12, thereby further increasing the volume of the refrigerator cavity 12.

Furthermore, in this embodiment, a first temperature detection element (not shown in the figure) is provided in the cold storage chamber 11. The temperature in the cold storage chamber 11 is detected by the first temperature detection element. When the temperature in the cold storage chamber 11 is too low or too high, the evaporator 41 can be controlled to stop or start. It is understood that the first temperature detection element can be placed in the top cold storage section 111 or in the side cold storage section 112.

In this embodiment, the aforementioned metal partition 3 includes a first plate 31, a second plate 32, and a third plate 33. The first plate 31 extends downward from the top wall of the inner liner 1, the second plate 32 extends from the bottom end of the first plate 31 towards the rear side wall of the inner liner 1, and the third plate 33 extends from the second plate 32 towards the bottom wall of the inner liner 1, so that the metal partition 3 has a roughly "Z"-shaped structure after being rotated 90° counterclockwise. A top cold storage section 111 is formed between the first plate 31, the second plate 32, and the walls of the inner liner 1 (specifically, the top wall, the peripheral side wall, and the rear side wall of the inner liner 1), and a lateral cold storage section 112 is formed between the third plate 33 and the walls of the inner liner 1 (specifically, the peripheral side wall and the rear side wall of the inner liner 1). This structure can fully utilize the space of the inner liner 1 to form a cold storage cavity 11 and a refrigeration cavity 12, thereby improving the space utilization rate of the inner liner 1.

In this embodiment, the volume of the top cold storage section 111 is larger than that of the side cold storage section 112. The evaporator 41 is installed in the top cold storage section 111. On the one hand, it is convenient to install the evaporator 41, and the pipe of the evaporator 41 can easily pass through the inner liner 1 and connect to other components of the refrigeration system. On the other hand, it is also convenient to form the cold storage chamber 11, making the formation of the cold storage chamber 11 and the refrigeration chamber 12 simpler.

In addition, when the evaporator 41 is running, the refrigerant in the top cold storage section 111 will be in a solid-liquid dual state. At this time, since the space of the top cold storage section 111 is large enough, it is easy to generate solid refrigerant so that in the event of a power outage or other emergency, the solid refrigerant can be converted into liquid refrigerant to further release the cooling capacity.

It should be noted that in this embodiment, along the direction from the refrigeration cavity 12 to the lateral cold storage section 112, the ratio of the depth of the lateral cold storage section 112 to the depth of the refrigeration cavity 12 (i.e., the ratio of the distance from the second plate 32 to the rear side wall of the inner liner 1 to the distance from the second plate 32 to the front end face of the inner liner 1) is in the range of 1:20 to 1:10. This ratio setting can further optimize the volume of the refrigeration cavity 12 on the basis of meeting the refrigeration requirements of the items in the refrigeration cavity 12, so as to maximize the volume of the refrigeration cavity 12.

In this embodiment, the third plate 33 has a first insulation layer on the side facing the refrigeration cavity 12. This first insulation layer can prevent the wall surface of the third plate 33 from over-condensing in a low-temperature environment. It can be understood that the second plate 32 has a second insulation layer on the side facing the refrigeration cavity 12 to prevent the wall surface of the second plate 32 from over-condensing.

It should be noted that, in order to achieve a fixed connection between the metal partition 3 and the inner liner 1, as shown in Figure 3, the edge of the metal partition 3 in this embodiment is provided with a connecting portion 34 along the circumferential direction. Multiple holes 341 are spaced apart on the connecting portion 34. Through holes can be provided on the peripheral sidewall of the inner liner 1. After the connecting portion 34 passes through the through holes, it is bent and fitted to the outer wall of the inner liner 1. Then, fasteners are passed through the holes 341 on the connecting portion 34 and fixed to the peripheral sidewall of the inner liner 1. In other words, the metal partition 3 and the peripheral sidewall of the inner liner 1 can be fixedly connected through the multiple holes 341 on the connecting portion 34. It is understood that after the connecting portion 34 is inserted into the through hole, it is necessary to seal the connecting portion 34 between the two holes. This can be achieved by applying sealant, or by placing a sealing gasket over the outside of the connecting portion 34, then inserting the sealing gasket into the through hole, and finally applying sealant to achieve a seal. Of course, in other embodiments, the metal partition 3 can be directly welded to the inner liner 1 to achieve a fixed and sealed connection between the two, thereby achieving a seal between the cold storage chamber 11 and the refrigeration chamber 12, as well as between the cold storage chamber 11, the refrigeration chamber 12 and the outside.

In other alternative technical solutions, to achieve a seal between the cold storage chamber 11 and the refrigeration chamber 12, this embodiment can also create an annular groove on the peripheral wall of the inner liner 1. In this case, a sealing gasket is fitted around the periphery of the metal partition 3, and then the metal partition 3 is interference-fitted into the annular groove through the sealing gasket to achieve a sealed connection between the metal partition 3 and the annular groove. Of course, to further improve the sealing performance between the metal partition 3 and the inner liner 1, sealant can also be applied to the sealing gasket.

In another alternative technical solution, in this embodiment, an annular groove is formed on the circumferential sidewall of the inner liner 1, and the metal partition 3 is inserted into the annular groove. The connection between the metal partition 3 and the annular groove is sealed with sealant, that is, the connection between the two is directly sealed by applying sealant.

In this embodiment, as shown in FIG2, the outer casing 2 includes a housing 21 and a door 22. One end of the housing 21 is open, and the door 22 can open or close the opening. When items need to be placed, the door 22 is opened. After the items are placed, the door 22 closes the opening (specifically, sealing the opening), thus sealing the refrigerator cavity 12 and ensuring that the refrigerator cavity 12 does not exchange heat with the outside. Preferably, the first plate 31 and the third plate 33 of the metal partition 3 are parallel to the door 22 of the outer casing 2, and the second plate 32 is perpendicular to the first plate 31.

Furthermore, referring to Figure 2, a refrigeration equipment compartment 13 is also provided at the bottom of the outer shell 2, below the inner liner 1. Other components of the refrigeration system, except for the evaporator 41, can be installed in the refrigeration equipment compartment 13, such as the compressor 42, condenser 43, and throttling element of the refrigeration system. In this embodiment, during operation, the refrigerant of the refrigeration system is compressed by the compressor 42 into a high-temperature, high-pressure refrigerant gas, which is discharged from the compressor 42 to the condenser 43, where it condenses into a liquid state. It then enters the throttling element, where it is throttled and depressurized to become a low-temperature, low-pressure liquid refrigerant. This liquid refrigerant then enters the evaporator 41 and evaporates. During evaporation, the refrigerant absorbs heat from the cold storage chamber 11, eventually turning into a gaseous state which is drawn back by the compressor 42 and compressed into a high-temperature, high-pressure gaseous state that flows back to the condenser 43. This cycle is repeated to achieve the refrigeration process of the refrigerant in the cold storage chamber 11.

As shown in Figure 4, in this embodiment, several trays 5 are spaced apart on the side of the metal partition 3 away from the lateral cold storage section 112. The trays 5 are located within the refrigeration chamber 12, allowing for the placement of items. Furthermore, since the trays 5 are directly connected to the metal partition 3, the cold energy within the lateral cold storage section 112 can be directly transferred to the trays 5 via the metal partition 3, further improving the cold energy transfer effect. In this embodiment, the trays 5 are spaced apart longitudinally.

In this embodiment, the refrigerator is also equipped with a power supply system, which can be a solar panel or mains power. Through the power supply system, the refrigerator can be electrically controlled, such as controlling the refrigeration system and transmitting information from the first temperature detection element.
