Detailed Description
Hereinafter, only certain exemplary embodiments are briefly described. As will be recognized by those of skill in the pertinent art, the described embodiments may be modified in various different ways 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 120 has a first surface 120A and a second surface 120B disposed opposite to each other; the first door 120 is provided with a recess 121, and the recess 121 extends from the first surface 120A toward the second surface 120B to form a receiving 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 being connected to the first surface 120A of the first door 120, and the outer surface 121B of the recess 121 being connected to the second surface 120B of the first door 120. The energy storage component 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 the refrigerator body 110 of the refrigerator 100, the refrigerator body 110 having 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 recess 121 of the first door 120 extends from the first surface 120A toward the second surface 120B to form a receiving cavity 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 recess 121 on the first door 120 extends from the first surface 120A toward the second surface 120B, that is, the receiving cavity may extend to the refrigeration cavity 112, with the opening of the receiving cavity being located outside the refrigerator 100. The receiving cavity may be used to receive the food product 300, and the cooling capacity in the refrigeration cavity 112 may be transferred into the receiving cavity through the recess 121 to cool the food product 300 in the receiving cavity, thereby effectively utilizing the cooling capacity transferred from the refrigeration cavity 112 to the door assembly. The opening of the receiving cavity is located outside the cooler 100 so that the food item 300 can be placed in the receiving cavity for refrigeration without opening the door assembly.
In one example, the recess 121 and the first door 120 may be integrally formed, so that the junction of the recess 121 and the first door 120 is smooth, and is not easy to be stained, 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, the second door 130 and the third door 140 being slidably stacked with respect to each other. The first door 120 is fixedly arranged at the refrigerator opening 111, so that movement of the accommodating cavity of the first door 120 can be reduced, and 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 compartment 112 may be achieved by sliding the second door 130 and the third door 140.
In one embodiment, referring to fig. 3 to 5, the first, second and third door bodies 120, 130 and 140 are disposed side by side in the first direction, and the first, second and third door bodies 120, 130 and 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 disposed 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 can be ensured to have a larger sliding distance, and the opening and closing of the refrigerator opening 111 are facilitated. Wherein, two second sliding rails 113 are oppositely arranged in the length direction of the refrigerator opening 111, and the second door 130 and the third door 140 relatively slide in the second sliding rails 113, so as to realize opening and closing of the refrigerator opening 111.
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 120, and the sealing strip 150 is located between the first surface 120A of the first door 120 and the second surface 120B of the first door 120. In this way, the seam between the first door 120 and the second door 130 may be sealed, improving the tightness of the door assembly.
In another example, a sealing strip 150 may be provided 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, improving the tightness of the door assembly.
The sealing strip 150 may be any sealing material that may be used in the prior art or in the future, and the sealing strip 150 may be fixed by being adhered to the first door 120 or the second door 130, which is not limited by the material and the installation method of the sealing strip 150 in the embodiment of the present 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 to stop the third door 140.
The height of the first pushrod 131 is not lower than the height of the lower surface of the third door 140, so as to ensure that the third door 140 can be stopped or limited, and prevent the third door 140 from sliding over the second door 130 to above the first door 120. Since the food 300 is accommodated in the accommodating chamber of the first door 120, the food 300 in the accommodating chamber may be placed higher than the opening of the accommodating chamber in some cases, and at this time, the third door 140 slides over the second door 130 to the upper side of the first door 120 to collide with the food 300 in the accommodating chamber. Therefore, by the stopper of the first pushrod 131, this can be avoided.
The first pushrod 131 may have a rod shape or other shape having an aesthetic effect. The opening and closing of the door assembly may also be facilitated by pushing the first push rod 131 to drive the sliding of the second door body 130.
In one example, a second push rod 141 may be provided 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 sliding of the third door body 140.
In one embodiment, the first door 120 may be fixedly connected to the second door 130, combined as a unit, and slid relative to the third door 140. The second door 130 drives the recess 121 on the first door 120 to slide.
In one example, since the recess 121 on the first door 120 extends into the refrigeration compartment 112 of the refrigerator body 110, the recess 121 slides along with the first door 120 as the second door 130 slides. When the food in the refrigeration chamber 112 is excessively stacked, the sliding of the concave portion 121 is likely to collide with the food in the refrigeration chamber 112. In order to avoid collision, a locking member may be provided to the second door 130, and in case that food in the refrigerating compartment 112 is excessively accumulated, the second door 130 may be locked by the locking member. With the second door 130 locked, the second door 130 cannot slide, and the refrigerating compartment 112 may be opened or closed by sliding of the third door 140.
In one embodiment, referring to fig. 6, the second door 130 and the third door 140 are disposed side by side in the first direction and slide relatively in the first direction. The second door 130 and the third door 140 are positioned at one side of the first door 120 in the second direction, wherein the first direction and the second direction are perpendicular.
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, and the opening and closing of the refrigeration chamber 112 are facilitated. The second door 130 and the third door 140 being located at one side of the first door 120 in the second direction means that the second door 130 and the first door 120 are disposed side by side in the width direction of the refrigerator body 110, and the third door 140 and the first door 120 are also disposed side by side in the width direction of the refrigerator body 110. The length of the first door 120 is matched with the length of the refrigerator body 110 to close one side of the refrigerator opening 111. The second door 130 and the third door 140 realize the opening or closing of 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 sliding rail 125, and the second door 130 and/or the third door 140 are slidably engaged with the first sliding rail 125. The first sliding rail 125 may be disposed on an edge of a side of the first door 120 and located between the first surface 120A of the first door 120 and the second surface 120B of the first door 120. The refrigerator opening 111 is provided with a second sliding rail 113 on a side opposite to the first door 120, and the second door 130 and the third door 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 may be glass, metal, plastic or other material 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 as long as the cold conducting can be realized.
In one example, the cooling coefficient of the housing 122 may be less than the cooling coefficient of the recess 121. Since the energy storage material is installed between the case 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 case 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 contained in the cavity. In the case of a new food product 300 being contained in the receiving cavity, the new food product 300 itself carries heat which is transferred through the recess 121 into the cavity 123 and then through the housing 122 into the refrigeration cavity 112. By using a material with a smaller coefficient of thermal conductivity for the housing 122, heat transfer from the food 300 itself into the refrigeration cavity 112 can be slowed down, avoiding affecting the refrigeration effect of the cooler 100.
In one embodiment, the depth of the receiving cavity is 15 to 22cm; the shape of the housing 122 matches the shape of the recess 121. For example, the holding cavity can hold bottled beverages such as mineral water, cola and the like. The depth of the receiving cavity may be less than the height of the food item 300 to be contained to facilitate the removal and placement of the food item 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 clamped with the outer surface 121B of the recess 121, so as to facilitate disassembly and assembly of the housing 122 and the recess 121, and replace the energy storage material, so as to 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 soft material and protrudes inward. After the shell 122 and the outer surface 121B of the concave portion 121 are fixed, the convex soft material can be clamped on the outer surface 121B of the concave portion 121, so that the cavity 123 is sealed, and volatilization and leakage of the energy storage material are avoided.
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 energy transfer area of the energy storage material and avoid leakage of the energy storage material.
In one example, after a certain height of energy storage material is contained in the housing 122, the housing is sleeved on the outer surface 121B of the recess 121 and is clamped at a preset position.
The energy storage material may be any material that can realize energy storage in the present or future, and the embodiment of the present application is not limited thereto. 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 fatty acid ester energy storage materials, oil ester energy storage materials, and composite energy storage materials made of an alpha-hydrogen-omega-hydroxy (oxy-1, 2-ethylene-diyl) polymer. It is understood that solid-liquid mixed state energy storage materials are also included within the scope of the present disclosure.

The refrigerator body 110 has a refrigerator opening 111 and a refrigerator compartment 112; the door assembly is disposed at the refrigerator opening 111 of the refrigerator body 110 for closing or opening the refrigerator compartment 112 of the refrigerator body 110, and the recess 121 extends into the refrigerator compartment 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 130 and the third door 140 are slidably engaged with the second slide rail 113. Referring to fig. 3 and 4, the refrigerator body 110 may be provided with two second slide rails 113 disposed opposite to each other, and the second door 130 and the third door 140 relatively slide in the two second slide rails 113 disposed opposite to each other.
