Description

Technical Field

[0001] The utility model belongs to the technical field of refrigerated containers, and in particular relates to an improvement to the door frame structure of a rear door of a refrigerated container. Background Art

[0002] When a container is used for a long time in a low-temperature environment, the rear door becomes difficult to open or cannot be opened due to ice, and it takes a long time to open it. Therefore, the rear door of an ordinary rear frame cannot meet the use needs in special environments. The current existing technology is to add a heating plate or a heating rod to the rear frame to heat the door strips. The heating effect is not good. After long-term use, the PVC of the rear frame is prone to aging, and it is easy to cause a short circuit when water enters, which poses a personal safety hazard.

[0003] The patent name is: A door frame section with a heating function, and the patent number is: CN202221509179.X. The disclosed structure is that a heating wire is set, and the position of the heating wire is arranged in the groove formed by the notch on the door frame section body and the metal cover plate, support ribs, support plate one, and support plate two. The heating is also carried out by electric heating. The electric heating temperature is high, which can easily cause aging of the door sealing components of the rear door and easy short circuit when encountering water, and has poor safety.

[0004] The above information disclosed in this background technology is only used to increase the understanding of the background technology of this application. Therefore, it may contain information that does not constitute the prior art known to ordinary technicians in this field. Utility Model Content

[0035] In some embodiments of the present application, a refrigerated container is provided, comprising:

[0036] The box body is composed of a plurality of box plates, and a refrigerated space for storing food is formed inside the box body.

[0037] And the door frame 100 is assembled on the box body and is used for installing and assembling the door body 200.

[0038] The door body 200 is rotatably connected to the door frame 100 to open or close the box body. The door body 200 is provided with a door sealing component 210 arranged along its circumference.

[0039] When connected, the door body 200 can be connected to the door frame 100 through a hinge. The door sealing component 210 is a door seal arranged along the circumference of the door body 200. When the door body 200 is closed, it can fit tightly with the door frame 100 through the door seal above it to achieve sealing of the entire box body, prevent the box body of the refrigerated container from leaking cold outward, and ensure the refrigeration effect of the refrigerated container.

[0040] In some embodiments, the door frame 100 includes:

[0041] Top side frame member 120;

[0042] and a bottom frame member 130 connected to the bottom of the top side frame member 120 .

[0043] The top and side frame members 120 include a top frame member 110 and a side frame member 120 . Two side frame members 120 are provided and are symmetrically connected at both ends of the top frame member 110 .

[0044] Both ends of the bottom frame member 130 are connected to the bottom positions of the two side frame members 120 to form a door frame 100 body.

[0045] The first heat-resistant and heat-insulating assembly is assembled on the top side frame member 120 , and a first embedding portion arranged along the circumference of the top side frame member 120 is formed inside the first heat-resistant and heat-insulating assembly.

[0046] In some embodiments, the first heat-resistant and heat-insulating assembly includes a plurality of first heat-resistant and heat-insulating components 400 arranged along the circumference of the top side frame.

[0047] Three first heat-resistant and heat-insulating components 400 are provided and respectively assembled to the side frame members 120 and the top frame member 110 .

[0048] In some embodiments, the first heat-resistant and heat-insulating component 400 is a high-temperature-resistant and heat-insulating polyethylene member.

[0049] The first embedding portion is composed of a plurality of first embedding grooves 410 connected in sequence. The plurality of first embedding grooves 410 are arranged along the circumferential direction of the top side frame member 120 .

[0050] The heat-conducting mounting assembly is at least partially embedded in the first embedding portion and can contact the top and side of the door sealing component 210 when the door body 200 is closed.

[0051] In some embodiments, the thermal conductive mounting assembly includes three thermal conductive mounting members 500 , which are respectively assembled in the first embedding grooves 410 of the two side frame members 120 and the first embedding groove 410 of the top frame member 110 .

[0052] The heat-conducting installation component is assembled on the first heat-resistant and heat-insulating component 400, and at least partially located in the first embedded portion. The first heat-resistant and heat-insulating component 400 is assembled on the top side frame member 120. The heat-conducting installation component can be insulated by the first heat-resistant and heat-insulating component 400, so that the heat of the first heating tube 610 can be transferred to the heat-conducting installation component in a more concentrated manner. At the same time, the heat-conducting installation component and the top side frame member 120 can be separated to avoid the heat transferred to the heat-conducting installation component through the first heating tube 610 from being transferred to the top side frame member 120, causing heat waste.

[0053] At the same time, the first heat-resistant and heat-insulating component 400 is wrapped around the outside of the heat-conducting mounting assembly. It is resistant to high temperatures and is not easily damaged after being heated. It can be used for a long time and is not prone to aging problems, thereby extending its service life.

[0054] The heat-conducting mounting assembly has heat conductivity, which can ensure that it can transfer heat to the door sealing component 210, so as to heat the door sealing component 210 through the transferred heat.

[0055] The first heating pipe 610 is arranged in the heat-conducting mounting assembly. Specifically, an installation space is formed inside the heat-conducting mounting component 500, and the first heating pipe 610 is sequentially inserted into the installation spaces of multiple heat-conducting mounting components 500.

[0056] The first heating pipe 610 is used to allow a flowing medium to pass through. The flowing medium passing through the first heating pipe 610 can transfer heat to the heat-conducting mounting assembly so that the heat-conducting mounting assembly heats the top and sides of the door sealing component 210 .

[0057] The first heating pipe 610 can be used as a first heating pipeline, into which a relatively high temperature flowing medium can be passed to transfer heat to the heat-conducting mounting assembly through the flowing refrigerant, and then to the door sealing component 210 to heat the top and sides of the door sealing component 210, so as to solve the problem that the door seal will not freeze and cause difficulty in opening the door.

[0058] In some embodiments, the flowing medium is water at a certain temperature, so that heat is provided by the water.

[0059] In order to realize the supply of hot water, the first heating pipe 610 can be connected to a hot water supply device, and the hot water supply device is assembled to the refrigerated container. The hot water supply device can adopt the existing structure.

[0060] When hot water is passed into the first heating tube 610, the hot water inside will dissipate heat and transfer the heat to the heat-conducting mounting assembly used to accommodate the first heating tube 610. The heat-conducting mounting assembly has heat conductivity and is in contact with the top and sides of the door sealing component 210 when the door body 200 is closed. It can transfer heat to the door sealing component 210, thereby heating the top and sides of the door sealing component 210 to prevent them from freezing.

[0061] The second heat-resistant and heat-insulating component 700 is assembled on the bottom frame member 130 , and a second embedding portion 710 arranged along the length of the bottom frame member 130 is formed inside the second heat-resistant and heat-insulating component 700 .

[0062] The second embedding portion is a second embedding groove formed in the second heat-resistant and heat-insulating component 700 , and is arranged along the longitudinal direction of the bottom frame member 130 .

[0063] In some embodiments, the second heat-resistant and heat-insulating component 700 is a high-temperature resistant and heat-insulating polyethylene member.

[0064] The heat-conducting support member 800 is at least embedded in the second embedding portion 710 and can contact the bottom of the door sealing component 210 when the door body 200 is closed.

[0065] The heat-conducting support member 800 is assembled on the second heat-resistant and heat-insulating component 700, and at least partially located in the second embedded portion 710. The second heat-resistant and heat-insulating component 700 is assembled on the bottom frame member 130. The heat-conducting support member 800 can be insulated by the second heat-resistant and heat-insulating component 700, so that the heat of the second heating tube 620 can be transferred to the heat-conducting support member 800 in a more concentrated manner. At the same time, the heat-conducting support member 800 and the bottom frame member 130 can be separated to avoid the heat transferred to the heat-conducting support member 800 through the second heating tube 620 from being transferred to the bottom frame member 130, causing heat waste.

[0066] At the same time, the second heat-resistant and heat-insulating component 700 is wrapped around the outside of the heat-conducting support 800. It is resistant to high temperatures and is not easily damaged after being heated. It can be used for a long time and is not prone to aging problems, thereby extending its service life.

[0067] The heat-conducting support member 800 has heat conductivity and is in contact with the bottom of the door sealing component 210 , and can transfer heat to the bottom of the door sealing component 210 .

[0068] The heat-conductive support member 800 has a supporting property and can provide support when a user steps in or out of the bottom frame member 130 .

[0069] The second heating pipe 620 is arranged in the assembly space formed by the heat-conducting support 800, and its two ends are respectively connected to the first heating pipe 610 for passing the flowing medium. The second heating pipe 620 can transfer heat to the heat-conducting support 800 through the flowing medium passed into the interior thereof, so that the heat can heat the bottom of the door sealing component 210.

[0070] The flowing medium flowing through the second heating pipe 620 can heat the bottom of the door sealing component 210 .

[0071] The first heating pipe 610 and the second heating pipe 620 are connected to form a connecting circulation flow path arranged around the door frame 100, so that the water flows along the door frame 100 to ensure uniform heating of the door sealing component 210 around the door body.

[0072] The second heating tube 620 is located in the assembly space surrounded by the heat-conducting support member 800 , and can be used to ensure that the heat generated by it can be transferred to the heat-conducting support member 800 when it is transferred to the surroundings, thereby ensuring that the heat can be transmitted to the door sealing component 210 .

[0073] The interior of the refrigerated container is a low-temperature environment. After the refrigerated container has been used for a period of time, ice may form on the door sealing component 210 and the door frame 100 of the rear door, causing the door body 200 to be unable to open normally.

[0074] The refrigerated container proposed in this embodiment is provided with a first heat-resistant insulation component and a second heat-resistant insulation component 700 on the door frame 100, and a heat-conducting installation component and a heat-conducting support component 800 are respectively built-in inside the first heat-resistant insulation component and the second heat-resistant insulation component 700, and a first heating pipe 610 and a second heating pipe 620 are provided in the installation space and the assembly space formed by them. A flowing medium is passed into the first heating pipe 610 and the second heating pipe 620, and heat is transferred to the door sealing component 210 through heat exchange with the flowing medium and the heat-conducting installation component and the heat-conducting support component 800 to heat it. The heating power source adopts a flowing medium with a certain temperature, and the heating temperature is constant and moderate, which is not easy to damage the door sealing component 210. At the same time, it can also reduce energy consumption, meet the current low-carbon and environmental protection requirements, and the use of flowing medium for heating is more convenient, there is no risk of circuit short circuit, and the safety is good.
