Description

Technical Field

[0001] This invention relates to the field of container insulation technology, and more specifically, to an insulated container. Background Technology

[0002] Currently, air source heat pump water heaters are increasingly popular among users due to their high energy efficiency and good comfort, and the industry is working to maximize the energy efficiency of air source heat pump water heaters.

[0003] In the existing technology, the external static heating water tank is the most commonly used type of air source water heater. The heat exchanger is wrapped around the outside of the water storage tank, which is safe and highly reliable.

[0004] However, because the heat exchanger in the existing technology is wrapped around the outside of the water storage tank and connected to the connecting pipe, it occupies the space of the movable insulation layer and reduces the heat preservation effect of the water heater. Summary of the Invention

[0005] The main objective of this invention is to provide an insulated container to solve the problem of poor heat preservation in existing water heaters.

[0006] To achieve the above objectives, the present invention provides a heat-insulating container, including an outer shell and an inner liner assembly, the inner liner assembly being disposed inside the outer shell. The heat-insulating container further includes: a sealing component covering the inner liner assembly, a vacuum layer being disposed between the sealing component and the inner liner assembly; and a first filling space being disposed between the sealing component and the inner wall surface of the outer shell, the first filling space being disposed of a heat-insulating medium.

[0007] Furthermore, the sealing component is made of a flexible material so that when the insulation medium applies pressure to the sealing component, the sealing component deforms toward the direction of the inner liner assembly.

[0008] Furthermore, the sealing component is provided with a first opening, through which a vacuum is drawn between the sealing component and the inner liner assembly to form a vacuum layer.

[0009] Furthermore, the sealing component includes a first wall surface and a second wall surface disposed opposite to each other, the first wall surface being in contact with the inner liner assembly and the second wall surface being in contact with the insulation medium.

[0010] Furthermore, the inner liner assembly includes: an inner liner body; a heat exchanger disposed on the outer wall surface of the inner liner body, and at least a portion of the first wall surface of the sealing member is in contact with the heat exchanger.

[0011] Furthermore, the inner liner assembly also includes: a connecting pipe fitting, the first end of which is connected to the heat exchanger; a working fluid support, which is disposed on the inner liner body, and a working fluid connector is disposed on the working fluid support, the second end of which is connected to the working fluid connector, and at least a portion of the first wall surface of the sealing component is respectively fitted to the connecting pipe fitting and the working fluid connector.

[0012] Furthermore, the insulated container also includes an inner liner body, on which a pipe joint is connected; the sealing component is provided with a clearance opening, through which at least a portion of the pipe joint extends.

[0013] Furthermore, the clearance opening is designed to be openable and closable, and after the insulation medium is filled, the clearance opening is in the open state.

[0014] Furthermore, the sealing component has a bag-like structure, and it is fitted onto the inner liner assembly and respectively attached to the inner liner assembly and the insulation medium.

[0015] Furthermore, the insulated container also includes: a bottom cover, on which the outer shell is disposed; and a top cover, which is disposed at the end of the outer shell away from the bottom cover, and a second filling space is provided inside the bottom cover and / or the top cover.

[0016] According to the technical solution of this invention, the insulated container includes an outer shell and an inner liner assembly, with the inner liner assembly disposed within the outer shell. The insulated container also includes a sealing component and a first filling space. The sealing component covers the inner liner assembly, and a vacuum layer is provided between the sealing component and the inner liner assembly. The first filling space is disposed between the sealing component and the inner wall surface of the outer shell, and an insulating medium is disposed within the first filling space. This arrangement avoids the problem of poor insulation performance caused by gaps between the insulating medium and the inner liner assembly during the filling process. By covering the inner liner assembly with a sealing component and providing a vacuum layer between the sealing component and the inner liner assembly, the vacuum layer provides insulation, compensating for the gaps between the insulating medium and the inner liner assembly, and improving the insulation effect of the insulated container.

[0022] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0024] Please refer to Figure 1 and Figure 2 The present invention provides a heat-insulating container, including an outer shell 1 and an inner liner assembly 2, the inner liner assembly 2 being disposed inside the outer shell 1. The heat-insulating container further includes: a sealing component 3 covering the inner liner assembly 2, a vacuum layer 4 being disposed between the sealing component 3 and the inner liner assembly 2; and a first filling space 5 being disposed between the sealing component 3 and the inner wall surface of the outer shell 1, the first filling space 5 being disposed of a heat-insulating medium.

[0025] The insulated container provided by the present invention includes an outer shell 1 and an inner liner assembly 2, the inner liner assembly 2 being disposed inside the outer shell 1. The insulated container further includes a sealing component 3 and a first filling space 5. The sealing component 3 covers the inner liner assembly 2, and a vacuum layer 4 is provided between the sealing component 3 and the inner liner assembly 2. The first filling space 5 is disposed between the sealing component 3 and the inner wall surface of the outer shell 1, and an insulating medium is disposed within the first filling space 5. This arrangement avoids the problem of poor insulation effect caused by gaps between the insulating medium and the inner liner assembly 2 during the filling process. By covering the inner liner assembly 2 with the sealing component 3 and providing a vacuum layer 4 between the sealing component 3 and the inner liner assembly 2, the vacuum layer 4 provides insulation, compensates for the gaps between the insulating medium and the inner liner assembly 2, and improves the insulation effect of the insulated container.

[0026] Specifically, the sealing component 3 is made of a flexible material so that when pressure is applied to the sealing component 3 by the insulation medium, the sealing component 3 deforms towards the inner liner assembly 2. Preferably, the sealing component 3 is made of plastic such as polyethylene or polyvinyl chloride, which ensures that the insulation medium is fully filled and that the compression of the sealing component 3 by the insulation medium makes the sealing component 3 fit tightly against the inner liner assembly 2. This maintains the vacuum state of the vacuum layer 4 while the sufficient insulation medium improves the insulation effect.

[0027] In the specific implementation process, the sealing component 3 is provided with a first opening, through which a vacuum is drawn between the sealing component 3 and the inner liner assembly 2 to form a vacuum layer 4. The vacuum layer 4 is used to perform vacuum insulation.

[0028] like Figure 2 As shown, the sealing component 3 includes a first wall surface and a second wall surface that are disposed opposite to each other. The first wall surface is in contact with the inner liner assembly 2, and the second wall surface is in contact with the insulation medium. This avoids gaps between the sealing component 3 and the insulation medium, which would affect the insulation effect, and ensures that the insulation medium passes through the sealing component 3 to provide insulation for the inner liner assembly 2.

[0029] In this application, the inner liner assembly 2 includes: an inner liner body 20; a heat exchanger 21 disposed on the outer wall surface of the inner liner body 20, and at least a portion of the first wall surface of the sealing member 3 being in contact with the heat exchanger 21. The inner liner assembly 2 also includes: a connecting pipe 22, the first end of which is connected to the heat exchanger 21; a working fluid support 23 disposed on the inner liner body 20, the working fluid support 23 having a working fluid connector 24, the second end of which is connected to the working fluid connector 24, and at least a portion of the first wall surface of the sealing member 3 being in contact with the connecting pipe 22 and the working fluid connector 24 respectively.

[0030] In actual processing, because the heat exchanger 21 needs to be connected to the connecting pipe 22, and the connecting pipe 22 needs to be connected to the working fluid connector 24, gaps can easily form between the heat exchanger 21 and the inner liner body 20 in the connection area. Figure 2 As shown, before the inner liner assembly 2 is installed into the outer shell 1, the sealing component 3 is first put on and a vacuum is drawn, so that a vacuum layer 4 is formed in the areas where gaps are easily formed in the inner liner body 20, such as the heat exchanger 21, connecting pipe fittings 22, working fluid support 23, working fluid joint 24 and pipe joint 25, which play a vacuum insulation role.

[0031] The insulation container also includes an inner liner body 20, on which a pipe connector 25 is connected; the sealing component 3 is provided with a clearance opening 30, through which at least a portion of the pipe connector 25 protrudes. The clearance opening 30 is closable; after the insulation medium is filled, the clearance opening 30 is in the open state. When a vacuum is drawn between the sealing component 3 and the inner liner assembly 2, the clearance opening 30 is closed; after the insulation medium is filled, the clearance opening 30 is opened to avoid affecting the vacuum effect of the vacuum layer 4.

[0032] In the embodiment provided by the present invention, the sealing component 3 has a bag-like structure, and the sealing component 3 is sleeved on the inner liner assembly 2 and respectively attached to the inner liner assembly 2 and the heat insulation medium. This achieves full coverage of the inner liner assembly 2.

[0033] Specifically, the insulated container also includes: a bottom cover 6, with the outer shell 1 mounted on the bottom cover 6; and a top cover 7, which is mounted on the end of the outer shell 1 away from the bottom cover 6. A second filling space 8 is provided inside the bottom cover 6 and / or the top cover 7. The second filling space 8 is filled with an insulating medium to optimize the overall insulation effect of the insulated container.

[0034] This application takes a water tank as an example. The inner tank body 20 is used to store water. During assembly, the sealing component 3 is first fitted onto the inner tank assembly 2, and a vacuum is drawn between the sealing component 3 and the inner tank assembly 2. At the same time, the air in the gaps between the heat exchanger 21, connecting pipes 22, or working fluid support 23 and the inner tank body 20 that cannot be filled by foaming is removed, forming a vacuum layer. Then, foaming agent is filled into the first filling space 5 to form a heat insulation layer. Because of the vacuuming, the air in the sealing component 3 is drawn away, resulting in internal suction, which can reduce the... The gaps between the heat exchanger 21, connecting pipe fittings 22, working fluid support 23, working fluid joint 24, pipe joint 25, etc., and the inner tank body 20, as well as the gaps that the foam insulation layer cannot fill, form a vacuum layer due to the vacuum. This makes it easy for heat to be lost due to the inability of the foam insulation layer to fill the gaps, and turns it into an insulation vacuum layer, which plays an insulation role. At the same time, it improves the insulation effect of the water heater tank and makes up for the disadvantage of the reduced insulation effect caused by the heat exchanger 21, connecting pipe fittings 22, etc. occupying the space of the insulation layer in the external plate static heating water tank.

[0035] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0036] The insulated container provided by the present invention includes an outer shell 1 and an inner liner assembly 2, the inner liner assembly 2 being disposed inside the outer shell 1. The insulated container further includes a sealing component 3 and a first filling space 5. The sealing component 3 covers the inner liner assembly 2, and a vacuum layer 4 is provided between the sealing component 3 and the inner liner assembly 2. The first filling space 5 is disposed between the sealing component 3 and the inner wall surface of the outer shell 1, and an insulating medium is disposed within the first filling space 5. This arrangement avoids the problem of poor insulation effect caused by gaps between the insulating medium and the inner liner assembly 2 during the filling process. By covering the inner liner assembly 2 with the sealing component 3 and providing a vacuum layer 4 between the sealing component 3 and the inner liner assembly 2, the vacuum layer 4 provides insulation, compensates for the gaps between the insulating medium and the inner liner assembly 2, and improves the insulation effect of the insulated container.
