Referring to fig. 1, 2, 4 and 5, an embodiment of the present application provides a board body.

Referring to fig. 1, 4 and 5, the plate body includes a metal plate body 100 and a glass plate body 200. The metal plate body 100 includes a panel 110, and the metal plate body 100 is provided with a heat source 300; the glass plate 200 is adapted to the panel 110 and is attached to the first side of the panel 110. Specifically, the metal plate body 100 may be made of a metal plate body with high thermal conductivity, such as an aluminum plate body or a copper plate body. The specific material is not limited, and can be selected according to actual needs. The glass plate 200 may be made of, but is not limited to, tempered glass.

It should be noted that, the "fitting the glass plate 200 to the panel 110" in the foregoing description may be specifically understood that the glass plate 200 is the same as or similar to the panel 110 in shape and size. It is further understood that a layer of glass sheet 200 is disposed over the panel 110 such that the glass sheet 200 substantially covers the panel 110, e.g., the front surface area a of the glass sheet 200 and the front surface area B of the panel 110 may have a relationship between a equal to 0.9B to 1.1B.

The glass plate 200 has a crystal clear texture, so that the plate has a more attractive visual effect. Meanwhile, since the glass plate 200 has a transparent property, the metal texture of the metal plate 100 can be obtained through the glass plate 200, so that different layers of visual effects can be created, and the outer surface of the plate is more abundant and has a stereoscopic impression. In addition, the heat source 300 is arranged on the metal plate body 100, so that the temperature difference at two sides of the plate body can be reduced by heating the heat source 300, and phenomena such as condensation or frosting on the outer surface of the plate body are avoided.

When the heat source 300 is a heating wire, the heating wire may be arranged according to the specific shape of the panel 110, for example, the heating wire may be uniformly laid on the panel 110, and at this time, the heating wire is laid in a manner that can make the panel 110 heated uniformly. Specifically, the panel 110 may have a rectangular structure, or may have a circular or oval structure, and the specific shape thereof is not limited. As shown in fig. 2, the panel 110 has a rectangular structure. When the panel 110 has a circular structure, the heating wires may be arranged in a spiral arrangement in which diameters are sequentially increased from the inside to the outside. In order to avoid electric leakage of the heating wire, a high-temperature-resistant insulator may be provided outside the heating wire.

When the heat source 300 is a printed resistive film, the printed resistive film may be a resistive material printed on the second side of the panel 110 by a printing technique. The printed resistive film may be composed of a conductive material and an insulating layer. The insulating layers are arranged on two sides of the conductive material and used for isolating the conductive material from the external environment. In some possible embodiments, the conductive material may be a carbon film, a metal film (e.g., copper, aluminum, tin plating, etc.), or other conductive material.

The printed resistor film has good plasticity and flexibility, can be manufactured into different shapes and sizes, has higher precision, stability and durability, and can provide reliable resistance value and performance. The manner of disposing the printed resistive film on the panel 110 is also more convenient and quick, greatly improving the manufacturing efficiency of the panel body. Meanwhile, the printed resistor film also has the characteristic of light weight and thinness, and provides favorable support for the development of the plate body in the direction of light weight and thinness.

When the heat source 300 is a resistive alloy layer, the panel 110 itself acts as a heat source. The resistive alloy layer may be composed of a conductive alloy layer and an insulating layer. Wherein the insulating layer wraps the periphery of the conductive alloy layer and is used for isolating the conductive alloy layer from the external environment. The material of the conductive alloy layer may include, but is not limited to, copper alloy, aluminum alloy, stainless steel, titanium alloy. By providing the panel 110 itself as a heat source, the problem of an increase in the thickness of the panel 110 due to an additional heat source added to the panel 110 is avoided. Making the panel 110 lighter and thinner.

In some embodiments of the present application, in case that the heat source 300 is a heating wire, the second side of the panel 110 is provided with a mounting groove, and the heating wire is fixed in the mounting groove. The heating wires and other heat sources can be nested in the mounting grooves, and the heating wires can be fixed by the mounting grooves. The installation groove is provided and the problem that the thickness of the plate body is increased by directly connecting the heating wire to the outer surface of the panel 110 can be avoided. The electric heating wires are nested in the mounting groove, so that the plate body is lighter and thinner.

In some embodiments of the present application, the metal plate body 100 is provided with a connector for electrically connecting the heat source 300 and an external power source. The connector may be electrically connected to an external power source by welding it to the power cord. The connector may also be connected to the power conductor using connection elements such as bolts, nuts and washers. In some possible embodiments, the connector may be a pluggable plug that is plugged directly onto an external power source, or onto a plug board, when in particular use.

Referring to fig. 1, in some embodiments of the present application, a backsize layer 400 is provided between the panel 110 and the glass plate 200, the backsize layer 400 being adapted to connect the panel 110 and the glass plate 200. The glue in the back glue layer 400 may specifically be polyurethane glue, epoxy resin glue, silicone glue, etc. It should be noted that, as much as possible, the back adhesive layer 400 is made of transparent glue. In a specific design, the back adhesive layer 400 may be applied to all sides of the glass plate body 200 facing the panel 110, or the back adhesive layer 400 may be applied only at edges or other portions of the sides of the glass plate body 200 facing the panel 110. The connection mode of glue bonding can avoid the shielding of other connection objects to the panel 110, thereby causing influence on visual effect. Visually integrating the panel 110 and the glass plate 200, the overall visual effect of the plate is lifted, making the surface of the plate more aesthetically pleasing and attractive.

Referring to fig. 3 to 5, the embodiment of the present application also provides a door assembly.

Referring to fig. 3, the door assembly includes a door liner 500 and a plate body according to any of the above embodiments, wherein a cavity is formed on a side of the plate body facing away from the glass plate body 200, and at least a portion of the door liner 500 is mounted in the cavity. Specifically, when the door liner 500 is installed inside the cavity, it may be installed inside the cavity by providing a foaming agent inside the cavity, and by the foaming agent.

It should be noted that, the "the door liner 500 is at least partially installed in the cavity" herein may be understood to include two cases, where a part of the structure of the door liner 500 is installed inside the cavity; the second case is that the entire structure of the door liner 500 is installed inside the cavity. For the first case, the depth to which the door liner 500 is installed in the cavity may be specifically designed according to the use environment. In the second case, it also includes a case where the outer surface of the end of the door liner 500 away from the panel 110 is flush with the edge of the opening side of the cavity, that is, the outer surface of the end of the door liner 500 away from the panel 110 forms the end surface of the opening side of the cavity, which can be understood as that the outer surface of the end of the door liner 500 away from the panel 110 seals the cavity.

In some environments of use, the temperature difference between the environments of the inner and outer sides of the door assembly is large, and thus condensation is often generated at the side having a higher temperature, such as the door assembly applied as a refrigerator door (but not limited to a refrigerator door). The condensation can greatly influence the appearance of the refrigerator door on one hand, and on the other hand increases the cleaning burden of personnel. Since the front surface of the refrigerator door is the largest heat loss surface generated by condensation, the surface is closely related to the thickness of the foaming layer of the door body, when the plate body of the embodiment is adopted, the temperature difference between the inside and the outside of the refrigerator can be balanced by the temperature rising of the metal plate body 100 through the heat source 300, so that the temperature of the refrigerator door can be controlled to be above the condensation temperature, and the condensation of the large surface of the refrigerator door body can be improved. After the problem of condensation is solved, the refrigerator door does not need to be provided with a thicker foaming layer to avoid the occurrence of the condensation phenomenon, and the refrigerator door body can develop towards a lighter and thinner direction.

In some embodiments of the present application, the left and right sides of the panel 110 are integrally formed with the side plates 120 (see fig. 4), or the periphery of the panel 110 is integrally formed with the side plates 120 (see fig. 5). Referring to fig. 3, in the case that the side plates 120 are integrally formed at the left and right sides of the panel 110, the upper and lower ends of the door liner 500 are provided with the upper end cap 510 and the lower end cap 520, and the panel 110, the side plates 120, the upper end cap 510 and the lower end cap 520 are coupled to each other to define a cavity therebetween. Referring to fig. 5, in the case where the side plate 120 is integrally formed around the panel 110, the panel 110 and the side plate 120 are combined to form a cavity. By integrally forming the panel 110 and the side plate 120, the leakage of the foaming agent can be prevented when the foaming agent is installed in the later stage, thereby avoiding the influence of the foaming agent on the appearance of the door assembly.

In some possible embodiments, the side plates 120 may be integrally formed at the left and right sides and the upper side of the panel 110, or the side plates 120 may be integrally formed at the left and right sides and the lower side of the panel 110. And the two adjacent side plates 120 are also integrally formed, i.e. the joint of the two adjacent side plates 120 has no gap.

The embodiment of the application also provides refrigeration equipment, which comprises a body and the door assembly according to any one of the embodiments, wherein the door assembly is arranged at the opening position of the body. Through setting up this door assembly, on the one hand, can make refrigeration plant's front have better pleasing to the eye effect, increase its visual appeal for its front looks abundanter and third dimension, more scratch-resistant, resistance to compression and wear-resistant, the cleanness of being convenient for more. On the other hand, the temperature difference between the inside and the outside of the refrigeration equipment can be balanced by the temperature rising of the heat source 300, so that the temperature of the door of the refrigeration equipment can be controlled to be above the condensation temperature, and the condensation of the large surface of the door body of the refrigeration equipment can be improved. After the problem of condensation is solved, the door body of the refrigeration equipment does not need to be increased in thickness to avoid the phenomenon of condensation, and the door body of the refrigeration equipment can be considered to be lighter and thinner. The refrigerating device may be a refrigerator, a freezer, a drug storage cabinet, or other refrigerating devices.

In some embodiments of the application, a freezing chamber is formed in the body, a drawer is arranged in the freezing chamber, and a panel of the drawer is formed by the plate body of any one of the embodiments.

In some embodiments of the present application, an air duct panel is disposed within the body, the air duct panel being formed from the plate of any of the embodiments described above.

When the door of the refrigeration equipment is opened, external hot and humid air can rapidly enter the interior of the refrigeration equipment, and when the temperature of the interior of the refrigeration equipment is low, the hot and humid air encounters the drawer panel and the air duct panel with lower temperature, frost is formed on the hot and humid air, and frost spots are formed on the hot and humid air. The frost spots formed on the air duct panel can cause unsmooth ventilation of the air duct panel, influence the circulation and distribution of cold air, and cause uneven temperature in the refrigerator. Thus, the food is excessively refrigerated in some areas and is not sufficiently cooled in other areas, which affects the shelf life and quality of the food. And frost spots formed on the drawer panel occupy space within the drawer, reducing the available space, thereby limiting storage of food and other items. The panel can quickly heat the air duct panel and the drawer panel to remove frost after the refrigeration equipment is opened, so that frost spots are formed on the surface of the panel in the moment of hot and humid air after the door is opened, and further damage caused by the frost spots can be effectively avoided. Specifically, a sensor can be arranged on a door body of the refrigeration equipment, and a control panel is arranged on the refrigeration equipment and is electrically connected with a switch and the sensor of the heat source. When the sensor senses that the door body is opened, the signal can be transmitted to the control panel, and the control panel further controls the heat source to heat.
