[0002] Refrigerators are common household refrigeration equipment, which are generally divided into refrigeration space and freezer space. French-style and cross-door door bodies generally have different freezer space arrangements. French-style refrigerators use the mode of pulling out the lower drawer, and the cross-door uses the mode of opening in pairs and adding a middle beam to seal the interval. Both have some shortcomings. The French-style refrigerator combines the drawer and the drawer door frame together. During use, the slide bars on both sides of the drawer bear the load, and problems are prone to occur with long-term use of the slide bars. Cross-door refrigerators need to be equipped with two door bodies that open in pairs, and a middle beam needs to be set in the freezer space at the junction of the two door bodies. The middle beam not only needs to occupy the freezer space, but is also inconvenient when placing larger refrigerated foods. If the middle beam is removed, there will be a gap at the junction of the two door bodies, which can easily cause cold leakage. Utility Model Content

[0028] The following are specific embodiments of the present invention, and the technical solution of the present invention is further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments, and the following embodiments do not limit the utility model involved in the claims. In addition, all combinations of the features described in the embodiments are not necessarily required for the solution of the utility model.

[0029] The principle and structure of the present utility model are described in detail below with reference to the accompanying drawings and embodiments. Example

[0030] For the double-door refrigerator 1, the two opposing door bodies of the refrigerator 1 have a certain thickness. Therefore, when the two opposing door bodies are closed, there needs to be a certain distance between the opposing sides of the two door bodies, otherwise the two opposing door bodies are not easy to close and open. Currently, a middle beam is set on the refrigerator 1 at the junction of the two door bodies, so that the gap between the two door bodies is located at the position of the middle beam, thereby avoiding cold leakage at the cross beam. However, the middle beam not only needs to occupy the freezing space, but is also inconvenient when placing larger refrigerated foods. If the middle beam is removed, there will be a gap at the junction of the two door bodies, which can easily cause cold leakage.

[0031] For this reason, Figure 1 , 2As shown in Figures 3, 4 and 5, a door sealing assembly suitable for use in a refrigerator compartment 2 of a refrigerator 1 is provided, comprising a door body, wherein the door body comprises a first door body 3 and a second door body 4 which open and close relatively to each other on the left and right sides, when the first door body 3 and the second door body 4 are closed, a first side of the first door body 3 is opposite to a second side of the second door body 4, a sealing member which can be extended and retracted relative to the second side is arranged on the first side, a retractable mechanism for controlling the retraction and extension of the sealing member is arranged on the first door body 3, and the sealing member is extended to seal a gap between the first side and the second side.

[0032] The sides of the first door body 3 and the second door body 4 are rotatably connected to the door frame, so as to achieve opening or closing relative to the door frame. The sides of the first door body 3 and the second door body 4 are provided with side sealing rubber pads 5 corresponding to the door frame, so as to ensure good sealing between the sides of the first door body 3 and the second door body 4 and the door frame.

[0033] The technical effects brought about by the above design are:

[0034] Since a retractable seal is provided, the seal is located at the gap between the sides of the first door body 3 and the second door body 4 when extended, thereby achieving shielding and sealing of the gap, compensating for the deficiency of the gap between the double-leaf door bodies.

[0035] like Figure 6 , 7 As shown, the telescopic mechanism includes a motor 6, a gear, and a rack 7, wherein the rack 7 is connected to the sealing member, and the motor 6 drives the rack 7 to telescope relative to the first side through the gear. The motor 6 is fixed to the first door body 3, and the gear is fixed to the rotating shaft of the motor 6, and the gear is meshed with the rack 7.

[0036] The technical effects brought about by the above design are:

[0037] The motor 6 drives the gear rack 7 mechanism to drive the sealing member to extend and retract. The structure is simple and the control is convenient. It is easy to be arranged on the door body without affecting the basic structure of the door body.

[0038] The telescopic mechanism is arranged in the door body of the first door body 3, and a telescopic hole 31 for the sealing member to be telescoped is opened on the first side.

[0039] The technical effects brought about by the above design are:

[0040] The sealing member is located in the telescopic hole 31 and is telescopically retracted, so that the sealing member can be retracted into the door body without affecting the external structure of the door body and without occupying external space.

[0041] The first door body 3 is provided with a guide rail 8 along the expansion and contraction direction of the sealing member, and the sealing member is slidably matched with the guide rail 8 .

[0042] The technical effects brought about by the above design are:

[0043] The guide rail 8 provides guidance for the movement of the seal, so that the seal can be extended and retracted stably with good directionality.

[0044] like Figure 8 , 9 As shown, the seal comprises a bracket and a first sealing rubber pad 9 fixed on the bracket, and a guide wheel 15 is provided at the end of the bracket to slide with the guide rail 8. In this embodiment, guide grooves serving as the guide rail 8 are provided at the upper and lower ends of the door body, and guide wheels 15 located in the guide grooves are provided at the upper and lower ends of the bracket, thereby achieving sliding cooperation between the seal and the guide rail 8.

[0045] The technical effects brought about by the above design are:

[0046] The sealing pad is beneficial to improving the sealing performance. The bracket is used to fix and support the sealing pad so that the sealing pad has a certain structural strength to avoid its deformation. The guide wheel 15 allows the sealing member to extend and retract smoothly.

[0047] The second side is provided with a second sealing pad 10 corresponding to the first sealing pad 9 .

[0048] The technical effects brought about by the above design are:

[0049] When sealing, the sealing member extends toward the second side of the second door body 4, so that the first sealing rubber pad 9 presses the second sealing rubber pad 10, so that the two are squeezed and contacted with each other, so that the sealing between the first door body 3 and the second door is better.

[0050] like Figure 8 As shown, the bracket is an insulating panel body, and the insulating panel body can be a VIP vacuum insulation panel 11.

[0051] The technical effects brought about by the above design are:

[0052] The heat-insulating plate body is beneficial to heat insulation, thereby preventing heat from being quickly conducted away from the sealing member, which is beneficial to heat preservation.

[0053] The second side or the sealing member is provided with a defrosting heating element 12 for preventing the sealing member from frosting. The defrosting heating element 12 may be, for example, an electrically controlled heating device such as a resistor wire. The defrosting heating element of this embodiment is provided on the second sealing rubber pad 10, and may of course be provided at other locations as long as it is convenient to prevent the first side and the second side from frosting.

[0054] The technical effects brought about by the above design are:

[0055] The defrosting heating element 12 is used for defrosting the joint between the sealing element and the second side, so as to prevent the two from being difficult to separate due to frost.

[0056] A human distance sensor 13 is provided on the first door body 3 or the second door body, and the telescopic mechanism controls the telescopic movement of the sealing member according to the distance of the human body relative to the first door body 3. The human distance sensor 13 can be an infrared ranging sensor, etc., for detecting the distance of the user approaching the door body. The human distance sensor of this embodiment is provided on the first door body.

[0057] The technical effects brought about by the above design are:

[0058] When it is detected that a human body approaches to a certain distance, it indicates that the person wants to open the door body. At this time, the sealing member is retracted, thereby facilitating the opening of the door body and avoiding the resistance of the sealing member from hindering the opening of the door body.

[0059] The refrigeration device is provided with an air duct 14, and the air duct 14 controls the air volume of the air duct 14 according to the expansion and contraction state of the sealing member and whether the door body is opened. The air duct 14 of this embodiment is a cold air inlet duct provided at the top of the refrigerating chamber 2 of the refrigerator 1, and is used to control the temperature in the refrigerating chamber 2.

[0060] The technical effects brought about by the above design are:

[0061] When the user approaches and detects that the human body distance L is less than the set distance L, the door seal opens, and the internal air duct 14 discharges air to reduce cold leakage during this period. When the user opens the freezer door, the freezer air duct 14 is closed. After the user uses it, the human body distance sensor 13 continues to work to determine the user's distance and then determine whether it is possible to continue to open the freezer door. When the user stops using it and the human body distance L is not less than the set distance L, the air duct 14 is closed and the door seal is closed.

[0062] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described, or replace them in similar ways, without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.

[0063] Although some terms are used more frequently in this article, the possibility of using other terms is not excluded. These terms are used only to more conveniently describe and explain the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model. The execution order of actions, steps, etc. in the devices and methods shown in the specification and the drawings can be implemented in any order as long as there is no special explicit limitation on the order and the output of the previous processing is not used in the subsequent processing. Similar sequential terms (for example, "first", "next", "secondly", "again", "then", etc.) used for the convenience of description do not mean that they must be implemented in such an order.

[0064] It should be understood by those skilled in the art that all directional references (for example, above, below, upward, up, downward, down, top, bottom, left, right, vertical, horizontal, etc.) are used descriptively in the drawings to facilitate the reader's understanding, and do not represent limitations (for example, on position, orientation or use, etc.) on the scope of the present invention as defined by the appended claims. They are only for the convenience of describing the present application and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the referred device or element must have a specific orientation or be constructed and operated in a specific orientation. The directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.

[0065] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" may include both "above" and "below". The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0066] In addition, some vague terms (e.g., substantially, certain, generally, etc.) may refer to slight inaccuracies or slight deviations of conditions, quantities, values, or dimensions, some of which are within the manufacturing deviation or tolerance range. It should be noted that the use of words such as "first" and "second" to define components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above words have no special meanings and therefore cannot be understood as limiting the scope of protection of this application.
