Description

TECHNICAL FIELD

[0001] The utility model relates to the field of refrigerator, in particular to a door seal structure of refrigerator and refrigerator. BACKGROUND

[0002] In modern refrigerator technology, especially for the design of cross door refrigerator and French refrigerator, the refrigeration chamber door usually adopts the design of opposite opening, which not only improves the appearance aesthetics of the refrigerator, but also optimizes the user's experience. However, in the process of realizing this opposite opening door structure, a key technical problem is how to effectively seal the gap between the refrigeration chamber doors to prevent cold air leakage and condensation phenomenon.

[0003] The traditional solution relies on setting a flip beam on one side of the refrigerator door. As a mechanical device, the flip beam can tightly fit the gap between the left and right refrigeration doors when the door is closed through its own flip action, thereby realizing the sealing effect. In order to further enhance the sealing performance and prevent condensation, an aluminum foil heater is usually arranged on the flip beam. These heaters are powered according to the preset control rules, and heat is generated to reduce the formation of condensate water, ensuring that the humidity and temperature inside the refrigeration chamber remain within the ideal range.

[0004] In addition, with the advancement of technology, some high-end refrigerators also introduce humidity sensors to optimize condensation control. These sensors can monitor the humidity level inside the refrigeration chamber in real time, and dynamically adjust the power-on rate of the aluminum foil heater according to the humidity size and the preset control algorithm. Although this intelligent control method improves the accuracy of condensation control to some extent, it also increases the complexity and cost of the system.

[0005] However, whether based on fixed control rules or humidity sensor feedback control, the presence of the flip beam is an indispensable element. This not only increases the overall manufacturing cost of the refrigerator, but also causes additional energy consumption due to the operation of the flip beam and its supporting heating system. In the current global context of advocating environmental protection and energy saving, this design is obviously not conducive to the energy efficiency optimization and sustainable development of the refrigerator.

[0006] Therefore, in order to overcome the cost increase and energy consumption problems caused by the flip beam in the prior art, the utility model puts forward an innovative technical solution. CONTENT OF THE UTILITY MODEL

[0030] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0031] The principle and structure of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0032] Traditional refrigerators have a flip-up beam on the door. As a mechanical device, the flip-up beam can tightly seal the gap between the left and right refrigerator doors when the door is closed, thus achieving a sealing effect, but this increases the complexity and cost of the system.

[0033] Therefore, in order to overcome the increased cost and energy consumption problems caused by the flip beam in the existing technology, this utility model proposes an innovative technical solution.

[0034] The scheme cancels the turnover beam, and rotates the left and right refrigeration door seals by 90°, and realizes the close sealing of the door gap by using the principle of opposite magnetism. The innovative design not only simplifies the structure of the refrigerator and reduces the manufacturing cost, but also is expected to contribute to environmental protection and energy saving by reducing unnecessary energy consumption.

[0035] As shown in Figures 1-2 The door seal structure of the refrigerator is provided. The refrigerator door of the refrigerator 001 is divided into a left door 01 and a right door 02, and the left door 01 and the right door 02 are respectively provided with the door seal 03 of the application. The door seal is provided with a permanent magnet. The magnetic poles of the permanent magnets on the left door and the right door of the refrigerator are opposite. When the left door and the right door are closed, the door seals on the opening side of the left door and the right door are attracted.

[0036] The door seal 03 is provided with a permanent magnet mounting portion.

[0037] The permanent magnet mounting portion is provided with a permanent magnet 031. The permanent magnet mounting portion wraps the permanent magnet. The magnetic poles of the permanent magnets 031 of the door seals 03 on the left door 01 and the right door 02 of the refrigerator 001 are opposite, one is N pole and the other is S pole. When the left door 01 is closed, the door seals 03 on the left door 01 and the right door 02 are attracted, preventing the cold in the refrigerator 001 from escaping from the gap between the left door 01 and the right door 02, causing condensation.

[0038] The door seal 03 is designed with a special connecting structure, such as buckles, screw holes or adhesive grooves, etc., to ensure that it is firmly installed on the opening side edge of the refrigerator door. The connection between the door seal and the refrigerator door is a relatively existing technology, which is not the focus of the application, so it is not described in detail.

[0039] The permanent magnet mounting portion is a key part of the connecting mounting portion and the permanent magnet 031, and its material and structure design is also important. In order to ensure the firm installation and effective magnetic transmission of the permanent magnet 031, the permanent magnet mounting portion is usually made of a material compatible with the permanent magnet 031, and is designed with appropriate grooves or channels to accommodate the permanent magnet 031. In addition, the permanent magnet mounting portion can also be provided with reinforcing ribs or support structures to improve its overall strength and durability.

[0040] In a further embodiment, the door seal is provided around the left door 01 and the right door 02, and the door seal around the left door and the right door is provided with a permanent magnet mounting portion, and the permanent magnet 031 is arranged in the permanent magnet mounting portion on the opening and closing side of the left door 01 and the right door 02. At this time, only the door seal 03 on the opening and closing side of the left door 01 and the right door 02 has the permanent magnet 031, and when the left door 01 and the right door 02 are closed, the permanent magnets 031 of the door seals 03 on the left door 01 and the right door 02 are attracted to each other.

[0041] In another embodiment, the door seal is provided around the left door 01 and the right door 02, and the door seal around the left door and the right door is provided with a permanent magnet mounting portion, and the permanent magnet 031 is arranged in the permanent magnet mounting portion on the opening and closing side of the left door 01 and the right door 02. At this time, only the door seal 03 on the opening and closing side of the left door 01 and the right door 02 has the permanent magnet 031, and when the left door 01 and the right door 02 are closed, the permanent magnets 031 of the door seals 03 on the left door 01 and the right door 02 are attracted to each other.

[0042] The permanent magnet 031 as the core component of the door seal 03, the magnetic pole configuration is the key to realize the close closure of the left and right doors 02. In the utility model, the magnetic poles of the permanent magnets 031 of the door seals 03 on the left door 01 and the right door 02 are opposite (one is N pole and the other is S pole), and this design makes the magnetic force between the two door seals 03 attract each other when the refrigerator door is closed, thereby effectively preventing the cold energy in the refrigerator 001 from leaking out. This magnetic attraction not only improves the sealing performance of the refrigerator 001, but also helps to reduce energy consumption and prolong the service life of the refrigerator 001.

[0043] As shown in Figures 4-5 Preferably, the permanent magnet 031 is annular. The permanent magnets 031 on the opening side of the left door 01 and the right door 02 are perpendicular to the refrigerator door they are installed on, and the permanent magnets 031 on the other side of the left door 01 and the right door 02 are parallel to the refrigerator door they are installed on.

[0044] When the door seal 03 is located on the inner side of the refrigerator door and perpendicular to the door, it can more effectively fit the refrigerator door frame or the edge of the adjacent refrigerator door, forming a tight barrier. This design reduces the gap caused by deformation of the refrigerator door, manufacturing tolerance or long-term use and wear, thereby significantly improving the sealing performance of the refrigerator 001. Due to the arrangement of the permanent magnets 031 that can be attracted to each other, the sealing effect is enhanced, and it is more difficult for the cold energy inside the refrigerator 001 to leak to the outside environment through the door gap. This helps to reduce condensation and frost around the refrigerator door, maintains the dryness and cleanliness of the inside of the refrigerator 001, and also helps to maintain the working efficiency of the refrigerator 001.

[0045] The door seal structure further comprises a heater arranged on the opening side of the side walls of the left door and the right door. The heater is used to prevent condensation. The heater 04 is arranged on the opening side of the side wall of the refrigerator door close to the door seal strip 03. The heater 04 is an aluminum foil heater 04.

[0046] The aluminum foil heater 04 can generate an appropriate amount of heat to increase the temperature of the door seal strip 03 and the surrounding area, thereby preventing condensation from occurring on the surface of the refrigerator door. Condensation not only affects the aesthetics of the refrigerator 001, but also can adversely affect the sealing performance of the door seal strip 03. Through heating, the aluminum foil heater 04 can ensure that the door seal strip 03 maintains a certain softness and elasticity, thereby better fitting the refrigerator door frame and improving the sealing effect. This helps to reduce cold air leakage and maintain the temperature stability inside the refrigerator 001.

[0047] As shown in Figure 3 In a further embodiment, the door seal structure further comprises a door closer arranged on the left door and the right door, the door closer 011 is provided with a waist hole 012, the refrigerator 001 is provided with a hinge plate on the cabinet, the door closer 011 and the hinge plate are connected through a hinge shaft, one end of the hinge shaft connected with the door closer 011 is arranged in the waist hole 012, and the hinge shaft moves in the waist hole 012 when the refrigerator door is opened and closed, so that there is no friction between the door seal strips 03 during the closing process of the refrigerator door. The hinge shaft not only rotates in the waist hole 012, but also moves relatively linearly. When the refrigerator door is closed from the beginning to the end, the refrigerator door has a linear motion to the side, so that there is no friction between the door seal strips 03 during the closing process of the refrigerator door.

[0048] A refrigerator comprises the door seal structure of the refrigerator of the present application. When the two refrigerator doors are closed, the door seal strips 03 are attracted to each other, and the gap between the two door seal strips 03 is less than 1.5 mm.

[0049] This scheme achieves the tight sealing of the door gap by canceling the turnover beam of the traditional refrigerator 001 and using the principle of opposite magnetism. This innovative design not only simplifies the structure of the refrigerator 001 and reduces the manufacturing cost, but also contributes to environmental protection and energy saving by reducing unnecessary energy consumption.

[0050] Compared with the prior art, the door seal structure of the refrigerator of the present application is provided. The door seal strip 03 is arranged on the left door 01 and the right door 02 of the refrigerator 001. The permanent magnet 031 is arranged in the permanent magnet mounting portion of the door seal strip 03. When the refrigerator doors are closed, the permanent magnets 031 of the door seal strips 03 of the left door 01 and the right door 02 are attracted to each other, so as to seal the gap between the left door 01 and the right door 02, prevent the cold air in the refrigerator 001 from escaping from the gap between the left door 01 and the right door 02, and prevent the phenomenon of condensation. Moreover, no other mechanical structure is needed, thereby solving the technical problem of the prior art refrigerator 001 that the turnover beam leads to a complex structure in order to prevent cold air leakage and condensation.
