Detailed Description
Various exemplary embodiments of the present disclosure are described in detail below with reference to the accompanying drawings and a preferred embodiment of the present utility model is described in detail below with reference to fig. 1 and 2:
as shown in fig. 1, the refrigerator comprises a box body 1 and a box door 2, and the cold energy in the refrigerator is leaked outwards from a gap between the box body 1 and the box door 2, so that the box body 1 and the box door 2 form a seal for cold energy leakage of the refrigerator through a door seal 3.
When the door is closed, the box frame surface 11 of the box body 1 and the door frame surface 21 of the box door 2 are in a parallel and completely opposite state, and the vertical projection of the door frame surface 21 is overlapped with the box frame surface 11; the dock seal 3 is provided between the box frame surface 11 and the door frame surface 21, and seals a gap between the box frame surface 11 and the door frame surface 21.
In the prior art embodiment shown in fig. 1, one side of the door seal structure 3 is pressed and embedded into the groove of the box frame and is firmly fixed, because the pressing and embedding type is adopted, the cold quantity on the one side leaks less, the other side is directly absorbed onto the box frame surface 11 through the magnetic strip 34, the magnetic strip 34 and the box frame surface 11 are in the form of surface absorption, the leakage path is shorter, when the plane of the box frame surface is uneven or the magnetism of the magnetic strip fails, the surface seal fails, and once the surface seal fails, the cold quantity can be continuously leaked due to no other supplementary measures, so that the product performance is affected.
Fig. 2 shows a sealing scheme of a door seal structure for a sealing box, which is provided by the utility model, and aims to solve the problem of increased cold leakage caused by poor surface-to-surface contact due to a magnetic attraction plane of the door seal structure and a metal plate plane (box frame surface) of a box opening in the conventional sealing scheme of the door seal structure.
The design direction is to make the embedded structure between the door seal structure and the box frame surface, and simultaneously reserve a groove structure on the box frame surface in advance and add a magnetic strip inside. At this time, when the door body is closed, the other side of the door seal structure is embedded into the box frame groove to form embedded seal; and the magnetic strips inside the door seal structure are magnetically attracted with the planes at the two sides of the box frame groove to form a face-to-face magnetic attraction seal. Therefore, the door seal structure is embedded into the box frame surface, so that the length of a leakage path of the cold quantity is increased, and the leakage quantity of the cold quantity can be reduced.
As shown in fig. 2, the dock seal 3 is made of a flexible material, for example, a flexible material with high elasticity such as rubber, and the dock seal 3 includes a first detent portion 31, a second detent portion 32, and a door coupling portion 33 that are integrally formed; wherein, a plane where the box door combining portion 33 is disposed is a sealing plane for sealing between the box body 1 and the box door 2, and the extending direction of the first clamping portion 31 and the extending direction of the second clamping portion 32 are perpendicular to the sealing plane, and meanwhile, the extending direction of the first clamping portion 31 is opposite to the extending direction of the second clamping portion 32;
the side of the door combining part 33 where the second clamping part 32 is located is tightly fixed on the door frame surface 21, and the second clamping part 32 is tightly fixed in the door frame groove, so that the door combining part 33 is tightly adhered and fixed with the door frame surface 2.
When the box door is closed, the first clamping part 31 can be embedded into the box frame groove in a pressing mode, and one side of the box door combining part 33 where the first clamping part is located is tightly attached to the box frame surface 11; when the door is opened, the first detent 31 is disengaged from the frame groove.
The box frame groove may be one or more, and the box frame groove and the door frame groove are formed in pairs.
In this embodiment, the opening of the box frame groove is completely opposite to the opening of the door frame groove, and the extending direction of the first clamping portion and the extending direction of the second clamping portion are on the same straight line. In other embodiments, the opening of the box frame groove may be opposite to the opening of the door frame groove in a staggered manner, and the extending direction of the first clamping portion and the extending direction of the second clamping portion are two parallel straight lines.
In addition, in order to ensure that the first clamping portion 31 is tightly attached to the box frame groove when the box door is closed, the magnetic strip 34 is arranged on the first clamping portion, and the magnetic strip 34 can be tightly attached to the inner wall of the box frame groove in a magnetic adsorption mode, so that the first clamping portion 31 is further sealed with the box frame groove, and cold leakage is avoided. As shown in fig. 2, magnetic strips 34 are respectively disposed on two sides of the first clamping portion 31, and when the door is closed, the magnetic strips 34 are correspondingly adsorbed on two opposite inner walls of the box frame groove, so that the first clamping portion 31 and the box frame groove are tightly attached, and leakage is reduced. Due to the adoption of the embedded type and the magnetic type, when the surface seal is invalid due to the fact that the metal plate plane of the cabinet opening of the box body is uneven or the magnetism of the magnetic stripe is invalid, the second embedded type sealing mode still has a corresponding sealing effect, and cold leakage can be further avoided.
