Detailed Description
In the following, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present application. Accordingly, the drawings and description are to be regarded as illustrative in nature, and not as restrictive.
FIG. 1 illustrates a schematic structural view of a door assembly according to an embodiment of the present application; fig. 2 shows a schematic structural diagram of an energy storage assembly according to an embodiment of the application.
As shown in fig. 1 and 2, the door assembly of the embodiment of the present application includes a first door body 120 and an energy storage assembly. The first door body 120 has a first surface 120A and a second surface 120B which are arranged oppositely; the first door body 120 is provided with a concave portion 121, and the concave portion 121 extends from the first surface 120A to the second surface 120B to form an accommodating cavity with an opening; the recess 121 has an inner surface 121A and an outer surface 121B, the inner surface 121A of the recess 121 is connected to the first surface 120A of the first door body 120, and the outer surface 121B of the recess 121 is connected to the second surface 120B of the first door body 120. The energy storage assembly comprises a shell 122 and energy storage materials, the shell 122 is sleeved on the outer surface 121B of the concave portion 121, a closed cavity 123 is formed between the shell 122 and the outer surface 121B of the concave portion 121, and the cavity 123 is used for containing the energy storage materials.
As shown in fig. 3 to 6, the door assembly of the embodiment of the present application may be applied to a refrigerator body 110 of a refrigerator 100, the refrigerator body 110 has a refrigerating chamber 112 and a refrigerator opening 111, and the door assembly may be installed at the refrigerator opening 111 to close or open the refrigerating chamber 112 of the refrigerator body 110.
The concave portion 121 of the first door body 120 extends from the first surface 120A toward the second surface 120B to form an accommodating chamber having an opening. The first surface 120A of the first door 120 faces the outside of the refrigerator body 110, and the second surface 120B of the first door 120 faces the refrigerating chamber 112. The concave portion 121 of the first door 120 extends from the first surface 120A toward the second surface 120B, that is, the receiving cavity may extend to the refrigerating chamber 112, and the opening of the receiving cavity is located outside the refrigerator 100. The receiving cavity can be used for containing the food 300, and the cold energy in the refrigerating chamber 112 can be transferred into the receiving cavity through the concave part 121 to refrigerate the food 300 in the receiving cavity, so that the part of the cold energy transferred from the refrigerating chamber 112 to the door assembly is effectively utilized. The opening of the receiving cavity is located outside the cooler 100, which allows the food item 300 to be placed in the receiving cavity for cooling without opening the door assembly.
In one example, the recess 121 and the first door 120 may be integrally formed, so that the joint between the recess 121 and the first door 120 is smooth and not easy to be hidden, thereby ensuring the safety and sanitation of the food 300.
In one embodiment, the first door 120 is fixedly disposed, and the door assembly further includes a second door 130 and a third door 140, and the second door 130 and the third door 140 are stacked in a relatively slidable manner. The first door body 120 is fixedly arranged at the opening 111 of the refrigerator, so that the movement of the accommodating cavity of the first door body 120 can be reduced, and the food 300 in the accommodating cavity can be stably stored and is not easy to fall down. On the other hand, the opening or closing of the refrigerating chamber 112 can be realized by the sliding of the second door 130 and the third door 140.
In one embodiment, referring to fig. 3 to 5, the first door 120, the second door 130, and the third door 140 are arranged side by side in a first direction, and the first door 120, the second door 130, and the third door 140 are relatively slidable in the first direction.
In a specific example, the first direction may refer to a length direction of the refrigerator body 110, the first door 120, the second door 130, and the third door 140 are arranged side by side in the length direction of the refrigerator body 110, and the second door 130 and the third door 140 slide along the length direction of the refrigerator body 110, so that the second door 130 and the third door 140 have a large sliding distance, and the opening and closing of the refrigerator opening 111 are facilitated. Two second sliding rails 113 are oppositely arranged in the length direction of the refrigerator opening 111, and the second door body 130 and the third door body 140 slide relatively in the second sliding rails 113, so that the refrigerator opening 111 is opened and closed.
In one embodiment, the first door 120 is adjacent to the second door 130, and a sealing strip 150 is disposed between the first door 120 and the second door 130.
In one example, the sealing strip 150 may be disposed on an edge of a side of the first door body 120, and the sealing strip 150 is located between the first surface 120A of the first door body 120 and the second surface 120B of the first door body 120. In this way, the seam between the first door 120 and the second door 130 can be sealed, and the sealing performance of the door assembly is improved.
In another example, the sealing strip 150 may be disposed on an edge of a side of the second door 130 to seal a seam between the first door 120 and the second door 130, thereby improving the sealing performance of the door assembly.
The material of the sealing strip 150 may be any material for sealing that may be used at present or in the future, and the fixing manner of the sealing strip 150 may be bonding with the first door body 120 or the second door body 130, and the material and the installation manner of the sealing strip 150 are not limited in this embodiment of the application.
In one embodiment, the third door 140 is stacked above the second door 130, and the second door 130 is provided with a first push rod 131, and the first push rod 131 is used for stopping the third door 140.
The height of the first push rod 131 is not lower than the height of the lower surface of the third door body 140, so that the third door body 140 can be stopped or limited, and the third door body 140 can be prevented from sliding over the second door body 130 to the upper side of the first door body 120. Because the food 300 is filled in the accommodating cavity of the first door body 120, in some cases, the food 300 in the accommodating cavity may be placed higher than the opening of the accommodating cavity, and at this time, the third door body 140 slides over the second door body 130 to the upper side of the first door body 120 and collides with the food 300 in the accommodating cavity. Therefore, by the stopper of the first push rod 131, the occurrence of this can be avoided.
The first push rod 131 may have a rod shape, or may have another shape having an aesthetic effect. The door assembly can be opened and closed conveniently by pushing the first push rod 131 to drive the second door body 130 to slide.
In one example, a second push rod 141 may be disposed on the third door body 140 to further facilitate the opening and closing of the door assembly by pushing the second push rod 141 to push the third door body 140 to slide.
In one embodiment, the first door 120 may be fixedly connected to the second door 130, integrated into a whole, and slide relative to the third door 140. The second door 130 drives the concave portion 121 of the first door 120 to slide.
In one example, since the concave portion 121 of the first door 120 extends into the refrigerating chamber 112 of the refrigerator body 110, the concave portion 121 slides along with the second door 130 when the first door 120 slides along with the second door. If the food in the refrigerating chamber 112 is stacked too high, the sliding of the recess 121 easily collides with the food in the refrigerating chamber 112. In order to avoid the collision, a locking member may be provided on the second door 130, and in case that the food in the refrigerating chamber 112 is excessively accumulated, the second door 130 may be locked by the locking member. When the second door 130 is locked, the second door 130 cannot slide, and the refrigeration chamber 112 can be opened or closed by sliding the third door 140.
In one embodiment, referring to fig. 6, the second door body 130 and the third door body 140 are arranged side by side in a first direction and slide relatively in the first direction. The second door body 130 and the third door body 140 are positioned at one side of the first door body 120 in a second direction, wherein the first direction and the second direction are perpendicular.
Wherein, the first direction may be a length direction of the refrigerator body 110, and the second direction may be a width direction of the refrigerator body 110. The second door 130 and the third door 140 slide relatively in the length direction of the refrigerator body 110, so that the second door 130 and the third door 140 have a larger sliding distance, which is convenient for opening and closing the refrigeration chamber 112. The second door 130 and the third door 140 are located on one side of the first door 120 in the second direction, which means that the second door 130 and the first door 120 are arranged side by side in the width direction of the refrigerator body 110, and the third door 140 and the first door 120 are also arranged side by side in the width direction of the refrigerator body 110. The length of the first door 120 matches with the length of the refrigerator body 110 to close the refrigerator opening 111 side. The second door body 130 and the third door body 140 open or close the refrigerator opening 111 at the other side of the refrigerator opening 111.
In one embodiment, the first door 120 is provided with a first slide rail 125, and the second door 130 and/or the third door 140 is slidably engaged with the first slide rail 125. The first sliding rail 125 can be disposed on an edge of a side of the first door body 120 and located between the first surface 120A of the first door body 120 and the second surface 120B of the first door body 120. The second sliding rail 113 is arranged on the opposite side of the refrigerator opening 111 from the first door body 120, and the second door body 130 and the third door body 140 can slide on the first sliding rail 125 and the second sliding rail 113 relatively, so as to open or close the refrigerator opening 111.
In one embodiment, both the recess 121 and the housing 122 are made of a cold conducting material. The cold conducting material can be glass, metal, plastic and other materials capable of conducting cold. The type of the cold-conducting material can be selected and adjusted according to actual needs, and the embodiment of the application does not limit the type of the cold-conducting material, so long as cold conduction can be realized.
In one example, the coefficient of thermal conduction of the housing 122 may be less than the coefficient of thermal conduction of the recess 121. Since the energy storage material is filled between the housing 122 and the recess 121, the energy storage material can store cold. The cold in the refrigerating chamber 112 is transferred into the cavity 123 through the shell 122, and the energy storage material in the cavity 123 stores the cold and transfers to the inner surface 121A of the recess 121 to refrigerate the food 300 in the containing cavity. In the case where a new food 300 is loaded into the receiving chamber, the new food 300 itself carries heat, and the heat is transferred to the cavity 123 through the recess 121 and then to the refrigerating chamber 112 through the housing 122. The shell 122 is made of a material with a small cold conduction coefficient, so that the heat transfer of the food 300 can be slowed down to the refrigerating chamber 112, and the refrigerating effect of the refrigerator 100 is prevented from being influenced.
In one embodiment, the depth of the receiving cavity is 15 to 22 cm; the shape of the housing 122 matches the shape of the recess 121. For example, bottled beverages such as mineral water and cola can be contained in the containing cavity. The depth of the receiving cavity may be less than the height of the food 300 to be contained to facilitate the taking and placing of the food 300. The shape of the housing 122 matches the shape of the recess 121 to form a cavity 123 for containing the energy storage material.
In one example, the housing 122 may be engaged with the outer surface 121B of the recess 121, so as to facilitate the detachment and installation of the housing 122 and the recess 121, replace the energy storage material, and avoid corrosion and acidification of the energy storage material in the cavity 123.
In one example, the opening of the housing 122 is made of a soft material and protrudes inward. After the shell 122 is fixed to the outer surface 121B of the concave portion 121, the protruding soft material can be clamped on the outer surface 121B of the concave portion 121, so that the cavity 123 is sealed, and the energy storage material is prevented from being volatilized and leaking.
In one embodiment, the energy storage material is a liquid energy storage material, and the liquid level of the liquid energy storage material in the cavity 123 is 1/2 to 4/5 of the height of the cavity 123, so as to ensure the cold transfer area of the energy storage material and avoid the energy storage material from leaking out.
In one example, after the housing 122 is filled with the energy storage material with a certain height, the energy storage material is sleeved on the outer surface 121B of the recess 121 and clamped at a preset position.
The energy storage material may be any material that can realize an energy storage function in the present or future, and the embodiment of the present application is not limited to this. In one example, the energy storage material may be a liquid mixture of substances having an energy storage effect. For example, the liquid energy storage material may be any one of a fatty acid ester energy storage material, an oil ester energy storage material, a composite energy storage material made of a polymer of α -hydro- ω -hydroxy (oxy-1, 2-ethanediyl), and the like. It is understood that the energy storage material in a solid-liquid mixed state is also included in the disclosure of the present application.

The refrigerator body 110 has a refrigerator opening 111 and a refrigerating chamber 112; the door assembly is disposed at the refrigerator opening 111 of the refrigerator body 110 for closing or opening the refrigerating chamber 112 of the refrigerator body 110, and the recess 121 extends into the refrigerating chamber 112 of the refrigerator body 110.
In one embodiment, the refrigerator body 110 is provided with a second slide rail 113, and the second door body 130 and the third door body 140 are slidably engaged with the second slide rail 113.
