Detailed Description
The present invention will be described in detail below with reference to specific embodiments shown in the drawings. These embodiments are not intended to limit the invention and structural, methodological, or functional modifications of these embodiments that may be made by one of ordinary skill in the art are included within the scope of the invention.
It should be noted that the term "comprises," "comprising," or any other variation thereof is intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Furthermore, the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
As shown in fig. 1, an embodiment of the present invention provides a door body 100, where the door body 100 is mainly used for opening and closing a cabinet or a box body with an opening on one side.
The appearance of the cabinet or the box body can be a vertical cabinet or a horizontal cabinet, or a box body with an opening at the front or an opening at the upper part, and in the case that the box body has a special position configuration, an embodiment in which the opening of the box body is vertically downward can also exist, and the invention does not limit the appearance setting of the cabinet or the box body. While the cabinet or case has been described above as having an opening on one side for the internal structure of the cabinet or case, it should be appreciated by those skilled in the art that the closing of the internal sub-doors results in the case or case having no open appearance for the particular "door-in-door" structure.
Further, in the present embodiment, the door body 100 is disposed on a refrigerator, and the refrigerator further includes a cabinet, a refrigeration system, and a control system. Wherein the front part of the box body is opened and a containing space is formed inside the box body for containing food or other articles which need refrigeration and preservation; the refrigerating system comprises a compressor, a condenser, an evaporator and a capillary restrictor, and the control system comprises a temperature controller, a thermal relay and an overload protector. Therefore, the refrigerating system provides a refrigerating and fresh-keeping function for the inside of the box body under the control signal provided by the control system, and quality damage of articles accommodated in the box body is prevented. The interior of the case may be divided into different compartments according to temperature, such as a refrigerating compartment, a freezing compartment, or a temperature-changing compartment, and the door 100 may be disposed at an opening of the case to open and close the compartments in a unified manner.
As further shown in fig. 2 to 4, the door body 100 includes a door shell 1 and door frames 2 disposed at two sides of the door shell 1, where the door frames 2 are disposed at two sides of the door shell 1, which means that they are disposed at least at two sides of the door shell 1 and configured such that one side is fixed to the door shell 1 and the other side extends toward the refrigerator body direction, thereby forming a side shield, so as to form a complete refrigerator body appearance. Of course, in other embodiments, the door frame 2 may be uniformly disposed around one side of the door shell 1, so as to further improve the overall structural strength of the door shell 1, and the door frame 2 may be made of the same metal or plastic material as the door shell 1, or may be made of a material with high structural strength different from the door shell 1, which are not necessarily required technical features for limiting the protection scope of the present invention.
Further, for the fixation between the structures, there may be various fixation methods between the door shell 1 and the door frame 2, and between the door frame 2 and the refrigerator cabinet. For example, the door shell 1 can be fixed with the door frame 2 through two sides, and the periphery of the door shell can be provided with corresponding limiting and fixing structures so as to be fixed on the door frame 2; the door frame 2 may be opened and closed in the left-right direction with the refrigerator body by providing a hinge on the left side or the right side, or may be opened and closed up and down by providing a hinge on the lower side or the upper side. Of course, the connection relation between every two of the structures can adopt movable connection modes such as pivot, sliding, detachable and the like, can also adopt fixed connection modes such as screw connection, welding, hinging, cementing, clamping and the like, and can be directly connected or indirectly connected.
As further shown in fig. 4, the door case 1 includes a panel 11 and a first extension 12, wherein the panel 11 is configured to have a high structural strength as an external appearance of the door body 100, and may be made of a metal material such as an aluminum alloy or a composite plastic material, whereas the first extension 12 may be identical in material to the panel 11 or may be made of a different material from the panel 11. The panel 11 connects the door frames 1 disposed at least at both sides of the door shell 1 to form a complete door body structure.
The door frame 2 is provided with a groove 21 corresponding to the first extension 12 on the side close to the door shell 1, wherein the cross section of the groove 21 may be square or circular, and the present invention is not limited thereto. In the present embodiment, the groove 21 is configured as a strip-shaped groove having a square cross section and extending along the length direction of the door frame 2, and the following description of each side surface of the inside of the groove 21 is also based on the embodiment in which the cross section of the groove 21 is configured as a square, but it should be understood that in the embodiment in which the cross section of the groove 21 is configured as a circle, there are corresponding side surfaces or internal structures, and those skilled in the art can of course adapt according to the technical solution provided by the present invention.
Further, the opening of the recess 21 is directed to the door case 1 side, and in this embodiment, since the door frame 2 is disposed at one side of the door case 1, particularly near one side of the refrigerator cabinet, the opening of the recess 21 is disposed perpendicular to the lateral extending direction of the panel 11, that is, the direction in which the panel 11 connects the left and right door frames 2. Of course, in the embodiment in which the door frame 2 is disposed on both sides of the door case 1, the opening of the recess 21 is oriented parallel to the lateral extending direction of the panel 11. In summary, the opening direction of the recess 21 is determined by the relative positions of the door shell 1 and the door frame 2, and in different embodiments, has different morphological characteristics.
In cooperation with the above-mentioned groove 21, the first extension 12 includes a sealing member 121 and a plug member 122, the sealing member 121 closing the opening of the groove 21 and forming a first cavity 41 with the groove 21, the inside of the first cavity 41 being filled with foaming material. In this way, by arranging the groove 21 on the door frame 2 and using the sealing member 121 arranged on the door shell 1, the first cavity 41 is jointly formed, and a space for arranging foaming materials or other materials for fixing is provided, so that compared with the traditional fixing mode of gluing at a gap or connecting two parts by using double faced adhesive tape, the combined tightness is better and the structure is more stable. Meanwhile, as the foaming material is used as the fixing material in the embodiment, the cost can be greatly reduced, the fault tolerance of the processing process is improved, and the technical effect of not affecting the original heat preservation and heat insulation performance of the device can be achieved in the embodiment that the user has heat preservation requirements on the door body 100.
In order to further improve the strength of the connection structure, one end of the above-mentioned plug connector 122 is connected with the sealing member 121, and the other end extends to the inside of the first cavity 41, so, the plug connector 122 stretches into the foaming material filled in the first cavity 41, the foaming material clamps the plug connector 122 to limit after foaming, and then the whole door shell 1 connected with the plug connector 122 is limited at a set position, meanwhile, as the door frame 2 is arranged at two sides of the door shell 1, the movable range of the door shell 1 can be further limited, and the balance of the door shell 1 is maintained, so that the technical effect that the door shell 1 and the door frame 2 cannot generate relative movement even in the demolding or transportation process is achieved.
It should be emphasized that the shapes of the sealing member 121 and the plug 122 are not particularly limited in this embodiment, and the sealing member 121 may be kept in the same arc as the panel 11, or may protrude in a direction away from the first cavity 41, so as to enlarge the volume of the first cavity 41 to accommodate more foam, or may be recessed in a direction close to the first cavity 41, correspondingly, although the volume of the first cavity 41 is lost, the recess formed in this embodiment may further cooperate with the groove 21, so as to enhance the fixing effect between the door shell 1 and the door frame 2. In the present embodiment, as shown in fig. 4, the insertion pieces 122 are disposed on one side of the seal 121 and form an angle of more than 90 ° with the seal 121, but in the embodiment in which the door frame 2 is disposed on both sides of the door shell 1, the insertion pieces 122 may be disposed on both sides of the seal 121 and perpendicular to the seal 121, thereby achieving the same technical effect of sealing the groove 21.
For a specific structure inside the groove 21, the groove 21 includes a first side 211, a second side 212 opposite to the first side 211, and a bottom 213 opposite to the sealing element 121, one side of the bottom 213 is connected to the first side 211, the other side is connected to the second side 212, the plug 122 includes an abutment 1221 and a hook 1222, the abutment 1221 abuts against at least one inner wall of the first cavity 41, and the hook 1222 extends away from the abutment 1221. This further improves the fixing effect between the door shell 1 and the door frame 2.
The contact portion 1221 may contact at least one of the first side portion 211 and the second side portion 212, so that when the panel 11 receives an external force, the contact portion 1221 may rub against the side portion and cooperate with the hook portion 1222 to form a resultant force opposite to the external force, so as to prevent the door case 1 from moving relatively. The abutting portion 1221 may be configured as an "L" to abut against the bottom portion 213, and in this case, a better fixing effect is achieved due to an increased contact area between the abutting portion 1221 and the inner wall of the groove 21.
In the present embodiment, the abutting portion 1221 is configured to abut against at least one inner wall of the first cavity 41, mainly for the purpose of saving the material of the first extension portion 12 and maintaining the structural integrity of the door shell 1 and the door frame 2, however, in other embodiments, the abutting portion 1221 may abut against a side surface of at least one of the first side portion 211, the second side portion 212, and the bottom portion 213, which is far from the first cavity 41, so that the technical effects expected by the present invention can be achieved.
The above-described arrangement in which the hook portion 1222 extends in a direction away from the contact portion 1221 is mainly aimed at extending the hook portion 1222 toward the center of the first chamber 41 and further maximizing the contact area with the foaming material, and therefore, the arrangement of the hook portion 1222 to have a special shape achieves the technical effect of increasing the contact area as well, and the arrangement can be alternatively implemented in the present invention.
In the present embodiment, the abutting portion 1221 abuts against the first side portion 211 near the first cavity 41, and the hook portion 1222 extends in the direction of the second side portion 212, which can achieve both the advantages of saving materials and enhancing structural stability. Of course, the extension length of the abutment portion 1221 may be as long as the abutment portion 1221 is configured as in the embodiment shown in fig. 4, in which the extension length extends to the middle of the first side portion 211 on the side close to the first cavity 41, or may be configured as long as the extension length extends directly to the intersection of the first side portion 211 and the bottom portion 213. Notably, in the latter embodiment, if the hook portion 1222 is simply configured to extend toward the second side portion 212 closely to the bottom portion 213, the technical effect of lifting the contact area of the hook portion 1222 and the foam material to limit the door shell 1 in multiple directions, which is expected by the present invention, is not achieved, and thus in this embodiment, the extending direction of the hook portion 1222 may be configured toward the middle of the second side portion 212 or away from the bottom portion 213.
In an embodiment in which the abutment 1221 abuts the first side 211 and the bottom 213 in sequence, the hook 1222 should be adapted to extend in a direction away from the bottom 213. Meanwhile, the hook portion 1222 may be connected to an end of the abutting portion 1221 away from the sealing element 121, or may be connected to any other position on the abutting portion 1221, which is not limited by the present invention.
For the process of assembling the above components, the present invention provides a door assembly method, which is only referred to as implementation reference of the present invention, and does not limit the protection scope of the present invention:
step 1, providing a die, wherein the die comprises an upper fixing piece and a lower fixing piece;
step 2, providing a door shell 1 and a door frame 2, and fixing the door shell 1 in an upper fixing piece, and fixing the door frame 2 in a lower fixing piece;
step 3, the upper fixing piece and the lower fixing piece are paired, at the moment, the plug connector 122 is inserted into the groove 21, the sealing piece 121 seals the groove 21 to form a first cavity 41, and the panel 11 of the door shell 1 is connected with the door frame 2;
step 4, pouring foaming material into the first cavity 41 and foaming;
and 5, separating the upper fixing piece and the lower fixing piece, and demolding the door body 100.
In order to further improve the heat preservation performance and further widen the application scenario of the door body 100 provided by the invention in the field of refrigerator or other refrigeration, the door body 100 further comprises a door liner 3 opposite to the door shell 1, the door frame 2 and the door liner 3 are jointly enclosed to form a second cavity 42, and foaming materials are filled in the second cavity 42. In this way, the formed insulation layer with a certain thickness, which is made of the foaming material, can effectively shield the temperature exchange between the interior of the refrigerator or other equipment box and the outside, and meanwhile, the insulation performance of the whole door body 100 is not affected by the special fixing scheme provided by the invention because the first cavity 41 is also fixed by adopting the foaming material, and the insulation layer has the technical effect which is not possessed by the traditional fixing mode.
The arrangement of other structures of the door liner 3 is not limited in practice, and as shown in fig. 2 to 3, a fitting portion for fixing a bottle holder or a shelf may be provided on a side of the door liner 3 away from the door shell 1 (i.e., a side close to a cabinet of the refrigerator), and pipes and lines for enhancing a refrigerating effect may be also disposed in the door liner 3, which are all technical modifications easily suggested by those skilled in the art according to the present invention, and thus the present invention will not be described in detail herein.
In addition, the present invention has a special configuration for the second side portion 212, and since the door shell 1 is in direct contact with the second side portion 212 when being fixed to the door frame 2, the fixing effect can be improved by increasing the contact area between the second side portion 212 and the door shell 1. Based on the above principle, in the present embodiment, the second extension portion 214 is provided on the side of the second side portion 212 close to the door shell 1, and the second extension portion 214 is attached to the panel 11 and extends in the direction away from the first cavity 41, so that the contact area between the door frame 2 and the door shell 1 can be further increased.
The above-described solution of the second extension 214 is incorporated into the solution of the door liner 3 provided in the foregoing, and additional technical effects can be further produced. That is, when the foaming material is poured into the second cavity 42, pressure can be further applied to the second extension portion 214, so that the distance between the second extension portion 214 and the panel 11 is smaller, and a better fixing effect is achieved. Meanwhile, in the present embodiment, a plurality of small grooves may be further configured on the side of the second extension portion 214 near the panel 11, and the foaming material may partially enter the small grooves during the pouring process, so as to achieve a certain effect of fixing the second extension portion 214 and the panel 11.
Further, the door frame 2 further includes a holding portion 22 and a bending portion 23, one end of the holding portion 22 is connected with the first side portion 211, the other end is connected with the bending portion 23, the door frame 2 is fixed to the door liner 3 through the bending portion 23, and the holding portion 22 is configured into an arc shape bending towards the second cavity 42, so that convenience is provided for a user to open and close the door, and meanwhile the structural integrity of the door body 100 is not affected. Of course, in the embodiment where the door frame 2 is disposed around the door shell 1, the grip portion 22 and the bending portion 23 may be disposed on different sides of the door frame 2, so as to adapt to different door opening and closing strategies.
In addition, in order to further enhance the foaming efficiency, the second side 212 is further provided with a through hole 2120, and the through hole 2120 communicates with the first cavity 41 and the second cavity 42 to form the foaming region 40. So configured, one of the first cavity 41 and the second cavity 42 can be foamed while the other can be synchronously foamed, that is, the foaming area 40 can be synchronously foamed, thereby improving the assembly efficiency of the door 100. Further, considering that the volume of the second cavity 42 is relatively large, when the assembly scheme of the door body 100 with the door liner 3 provided by the invention is implemented, the foaming material is poured into the second cavity 42, and enters the first cavity 41 through the through hole 2120 to communicate and fill the whole foaming region 40, so that better fixing and foaming effects are achieved.
With respect to the configuration of the number and the positions of the through holes 2120, since the amount of the foaming material flowing into the first cavity 41 needs to be controlled in the present embodiment, the situation that the foaming material flows into the first cavity 41 too much to cause the sealing member 121 to tilt or other sealing difficulties is prevented, and in the case that the groove 21 is configured as a strip-shaped groove, the through holes 2120 are arranged at intervals on the side of the groove 21 close to the second cavity 42, and the opening positions of the through holes 2120 can be the second side 212 shown in fig. 4 or the bottom 213, so that the expected technical effects can be achieved. Of course, when the grooves 21 are configured in other groove shapes, there is no need to perform a space arrangement, and in the embodiment in which the grooves 21 are configured to be spaced on the door frame 2, a single groove 21 can have one through hole 2120 to achieve the technical effects expected by the present invention.
For the configuration of the structure of the through hole 2120, the through hole 2120 includes a first port 2121 and a second port 2122, the first port 2121 is located on a side of the through hole 2120 close to the first cavity 41, the second port 2122 is located on a side of the through hole 2120 close to the second cavity 42, and further, the first port 2121 is smaller in diameter than the second port 2122. This slows down the rate of foam entering the first cavity 41, further preventing the seal 121 from being ejected when the foam fills the first cavity 41.
The present invention further provides a door assembly method, which is only used as a reference for implementing the present invention and is not intended to limit the scope of the present invention, by adapting the door body with the structures of the door liner 3, the through hole 2120, etc.:
step 1, providing a die, wherein the die comprises an upper fixing piece and a lower fixing piece;
step 2, providing a door frame 2 and a door liner 3, and fixing the door frame 2 and the door liner 3 to form a first assembly;
step 3, fixing the door shell 1 in an upper fixing piece, and fixing the first assembly piece in a lower fixing piece;
step 3, the upper fixing piece and the lower fixing piece are paired, at the moment, the plug connector 122 is inserted into the groove 21, the sealing piece 121 seals the groove 21 to form a first cavity 41, the door shell 1 and the first assembly form a second cavity 42, and the first cavity 41, the through hole 2120 and the second cavity 42 form a foaming area 40;
step 4, pouring foaming material into the second cavity 42 and foaming, wherein the foaming material flows into the first cavity 41 through the through hole 2120 and fills the whole foaming area 40;
and 5, separating the upper fixing piece and the lower fixing piece, and demolding the door body 100.
In summary, according to the door body provided by the invention, the first cavity 41 is formed by surrounding the limiting grooves 21 formed on the door shell 1 and the door frame 2, the first cavity 41 is filled with the foaming material to form a first layer of fixation, and meanwhile, the plug connector 122 extending from the door shell 1 to the interior of the first cavity 41 extends into the foaming material to form a second layer of fixation so as to further limit the relative position between the door shell 1 and the door frame 2, thereby achieving the technical effect of preventing the door shell 1 from tilting during demolding or transportation; in addition, compared with the prior art, the pouring foaming material is fixed by gluing or double-sided adhesive tape, the operation is simpler, the automatic production is convenient, meanwhile, the foaming material belongs to a heat preservation and insulation material, and the heat preservation and insulation performance of the door body can be improved or maintained to a certain extent.
