The present invention relates to refrigerator arts, and disclose a kind of board face structure of refrigerator door panel, including inner casing, shell and insulating layer, and the two sides of the insulating layer are fixedly connected to thermal insulation board, and the inner casing and shell are fixedly connected with the other side of two thermal insulation boards respectively.The present invention can be realized high-efficiency insulated as heat-insulated main material using the ultralow thermal conductivity of aeroge using aeroge, it avoids damaging ozone layer using traditional blown polyurethane materials, it is more in line with environmentally protective theory, convenient for promoting the use of, then the setting for passing through thermal insulation board, play the role of double thermal insulation, heat insulation effect is improved comprehensively, while can also play reinforcement effect, improves impact resistance, avoid collision it is impaired, to improve service life.

Description

A kind of board face structure of refrigerator door panel

Technical field

The present invention relates to refrigerator art, specially a kind of board face structure of refrigerator door panel.

Background technique

Refrigerator is a kind of common household electrical appliances, is to maintain a kind of refrigeration equipment of constant low temperature, mainly by thermal-insulating body, heat preservation The application attachment such as door-plate, refrigeration system and electrical system is constituted, and wherein thermal-insulating body and thermal insulation door panel play heat-insulated and heat preservation and make With generalling use sponge and asbestos etc. as thermal insulation material, but this kind of material heat-insulating capability is not in the early-stage development of refrigerator Height easily causes heat losses, causes energy consumption of refrigerator higher, and polyurathamc is mostly used to do thermal insulation material, thermal coefficient at present Lower and service life is longer, quickly instead of product before, has been widely used.

Polyurathamc is exactly rigid polyurethane foam, and abbreviation hard polyurethane foam, hard polyurethane foam is mostly closed pore knot Structure has that insulation effect is good, light-weight, specific strength is big and the good characteristics such as easy for construction, at the same also have sound insulation, it is shockproof, The features such as being electrically insulated, is heat-resisting and cold-resistant, is widely used in the cabinet heat-insulating material of refrigerator and refrigerator-freezer, but polyurethane foam material contains There is fluoride, ozone layer can be destroyed, do not meet environmentally protective theory, it is therefore desirable to is a kind of with high-efficiency insulated environment-friendly type refrigerator Door-plate.

Summary of the invention

In view of the above problem of the existing technology, an aspect of of the present present invention is designed to provide a kind of plate of refrigerator door panel Face structure.

To achieve the goals above, the board face structure of a kind of refrigerator door panel provided by the invention, including inner casing, shell and guarantor Warm layer, the two sides of the insulating layer are fixedly connected to thermal insulation board, and the inner casing and shell are another with two thermal insulation boards respectively Side is fixedly connected.

Preferably, the thermal insulation board includes internal layer, middle layer and outer layer, and the internal layer is fixedly connected with insulating layer, institute Internal layer, middle layer and outer layer is stated to be arranged successively from inside to outside and vacuum compression moulding.

Preferably, the main body of the insulating layer is aeroge.

Preferably, the internal layer is polyethylene film.

Preferably, the middle layer is aluminium foil.

Preferably, the outer layer is ABS thin plate.

Compared with prior art, the board face structure of refrigerator door panel provided by the invention, has the advantages that

The present invention using aeroge as heat-insulated main material, using the ultralow thermal conductivity of aeroge, can be realized it is high-efficiency insulated, It avoids damaging ozone layer using traditional blown polyurethane materials, is more in line with environmentally protective theory, convenient for promoting the use of, Again by the setting of thermal insulation board, play the role of double thermal insulation, improves heat insulation effect comprehensively, while reinforcement effect can also be played, mention High impact-resistance, avoid collision it is impaired, to improve service life.

Specific embodiment

In order to enable the purposes, technical schemes and advantages of the embodiment of the present disclosure are clearer, below in conjunction with disclosure reality The technical solution of the embodiment of the present disclosure is clearly and completely described in the attached drawing for applying example.

Unless otherwise defined, the technical term or scientific term that the disclosure uses should be tool in disclosure fields The ordinary meaning for thering is the personage of general technical ability to be understood.The similar word meaning such as " comprising " or "comprising" used in the disclosure Point out that element or object before the existing word are covered the element for appearing in the word presented hereinafter or object and its be equal, without Exclude other elements or object." connection " either the similar word such as " connected " is not limited to physics or mechanical company It connects, can also include electrical connection, it is either direct or indirect."upper", "lower", "left", "right" etc. are only used for table Show relative positional relationship, after the absolute position for being described object changes, then the relative positional relationship may also correspondingly change.

In order to keep the following explanation of the embodiment of the present disclosure to understand and concise, known function and known portion is omitted in the disclosure The detailed description of part.

A kind of board face structure of refrigerator door panel referring to FIG. 1-2, including inner casing 1, shell 2 and insulating layer 3, insulating layer 3 Two sides are fixedly connected to thermal insulation board 4, and inner casing 1 and shell 2 are fixedly connected with the other side of two thermal insulation boards 4 respectively.

Thermal insulation board 4 includes internal layer 41, middle layer 42 and outer layer 43, and internal layer 41 is fixedly connected with insulating layer 3, internal layer 41, Middle layer 42 and outer layer 43 are arranged successively from inside to outside and vacuum compression moulding, and internal layer 41 is polyethylene film, and middle layer 42 is Aluminium foil, outer layer 43 can be improved insulation effect by the Combination Design of polyethylene film, aluminium foil and ABS thin plate for ABS thin plate, Also act as the reinforcement effect of end of door plate simultaneously, improve integral strength and anti-impact force, avoid collision it is impaired, to improve using the longevity Life.

The main body of insulating layer 3 is aeroge, is mixed into, will not be burnt by Silica hydrogel, methanol, water and a small amount of aqua ammonia, It is a kind of heat-insulating material, thermal coefficient just corresponds to conventional polyurethanes heat-insulating material without the substance for destroying atmospheric ozone layer Ten halfs, temperature transmitting can be blocked well, realize the effect of energy saving dilatation, and appearance is in solid-like, very It is sturdy and durable, 1400 degrees Celsius of high temperature can be born, the heat preservation insulation effect of refrigerator door panel can be effectively improved.

The content being not described in detail in this specification belongs to the prior art well known to professional and technical personnel in the field.
