Fig. 1 is a perspective view of one embodiment of the refrigerator of the present utility model, and a refrigerator 100 of the present embodiment has an approximately rectangular parallelepiped shape. The refrigerator 100 includes a cabinet 110 and a door 120 hinged to the cabinet 110, and a plurality of refrigerating and/or freezing compartments are defined by the cabinet 110 and the door 120.

The refrigerator 100 in the present utility model is a refrigerator having a vacuum fresh-keeping function, which is realized by the fresh-keeping box 200.

The storage cavity 250 is formed in the preservation box 200, the preservation box 200 is detachably connected with the door body 120 (specifically, the door liner), the preservation box 200 is convenient to be taken down from the door body 120, and the use convenience of the preservation box 200 is improved.

Referring to fig. 2 to 4, the fresh-keeping box 200 includes a box body 210 and a cover body 220, wherein a vacuum-pumping interface 221 is provided on the cover body 220, and the vacuum-pumping interface 221 is used for matching with a vacuum-pumping assembly, so that the vacuum-pumping assembly is communicated with the storage cavity 250 and vacuumizes the storage cavity 250.

The vacuum pumping assembly can enable the inside of the preservation box 200 to reach a vacuum state, wherein the vacuum state is not an absolute vacuum state, but is a low-pressure state, so that the preservation of the stored articles in the preservation box 200 is improved.

The vacuum pumping assembly comprises a vacuum pump, a vacuum pumping pipeline and a vacuum pumping joint 140, wherein the vacuum pumping pipeline is used for communicating the vacuum pump with the vacuum pumping joint 140, the vacuum pumping joint 140 is detachably connected with the vacuum pumping joint part 221, and the vacuum pump provides vacuum pumping power for the whole vacuum pumping assembly.

The vacuum connector 140 is disposed on the door 120, specifically on the inner container of the door, and the vacuum connector 140 can be communicated with the storage cavity 250.

When the storage cavity 250 needs to be vacuumized, the vacuumizing connector 140 is communicated with the storage cavity 250, namely the vacuumizing connector 140 is connected with the vacuumizing interface 221, at the moment, the vacuum pump is started, and gas in the storage cavity 250 can be discharged from the vacuumizing connector 140 and the vacuumizing pipeline to the vacuum pump, so that low pressure in the storage cavity 250 is realized.

When the vacuum fresh-keeping box 200 needs to be removed from the door 120, the vacuum connector 140 is turned over to be separated from the vacuum fresh-keeping box 200, that is, the vacuum connector 140 is separated from the vacuum connector 221.

According to the utility model, the vacuumizing connector 140 is arranged on the door liner in a turnover manner, and the vacuumizing connector 140 is turned upwards or downwards according to the need of vacuumizing the vacuum preservation box 200, so that the operation is convenient and easy to use.

In some embodiments of the present utility model, referring to fig. 1, a shelf 130 is provided on the door liner, and the vacuum fresh-keeping box 200 is directly placed in the shelf 130, so as to realize detachable connection between the fresh-keeping box 200 and the door liner. When the fresh box 200 needs to be taken out of the refrigerator 100, the fresh box 200 is directly taken out from the shelf 130.

The fresh box 200 includes a box body 210, a cover 220, and a sealing strip 230. The box 210 forms a containing cavity with an open top, and the cover 220 is detachably disposed on the top of the box 210. The box 210 and the cover 220 are buckled to form a storage cavity 250.

The cover 220 is provided with a first plug-in connection part 222, the sealing strip 230 is provided with a second plug-in connection part 233, and the cover 220 and the sealing strip 230 are fixedly connected through plug-in connection between the first plug-in connection part 222 and the second plug-in connection part 233.

The sealing strip 230 is arranged on one side of the cover 220 facing the box 210, after the cover 220 is buckled with the box 210, the sealing strip 230 is abutted with the opening end of the box 210, the cover 220 and the box 210 are further clamped under the action of external force such as a buckle, so that the sealing strip 230 is compressed under force, and therefore, a seal is formed at the joint of the cover 220 and the box 210, and further, the seal of the preservation box is realized.

The case 210 is made of stainless steel, and the cover 220 is made of plastic.

The box body 210 is made of 304 stainless steel plates with the wall thickness of 0.5-0.8mm, and the stainless steel materials are suitable for storing high-salt, high-acid and high-oil food materials.

The case 210 and the cover 220 are made of two materials, and can achieve the following beneficial effects: the box 210 is made of stainless steel as the main body of the container, so that the problem that hidden danger is generated to food safety due to molecular permeation and plasticizer decomposition of plastic materials in the prior art can be avoided; the cover 220 is made of plastic, and the cover 220 mainly plays a role of closing the top opening of the box body, and is not in contact with food, so that the negative effect on food safety is small, and the plastic material is convenient for processing the cover.

Because the box body 210 and the cover body 220 are made of different materials, the sealing structure between the sealing strip 230 and the box body 210 and between the sealing strip 230 and the cover body 220 needs to be improved for achieving the optimal sealing and fresh-keeping effects.

Referring to fig. 5 and 7, a flat portion 211 is provided on the top circumferential edge of the case 210, the flat portion 211 extends horizontally toward the outer circumferential side of the case 210, a bead 213 is provided on the bottom side of the flat portion 211, and the bead 213 curls from the outer end side of the flat portion 211 toward the direction approaching the flat portion 211.

Referring to fig. 6 again, the sealing strip 230 is provided with a transverse portion 231 and a vertical portion 232, the transverse portion 231 and the vertical portion 232 are in an integrated structure, the top of the transverse portion 231 is provided with a second plugging portion 233, and the second plugging portion 233 is plugged with the first plugging portion 222 so as to fixedly mount the sealing strip 230 on the cover 220.

After the cover 220 is fastened to the case 210, the bottom plane (denoted as a first surface 236) of the transverse portion 231 contacts and seals with the plane portion 211, the vertical portion 232 is located inside the case 210, the vertical portion 232 is provided with a fin 238 on a side (denoted as a second surface 237) facing the inner side wall of the case 210, and the fin 238 contacts and seals with the inner side wall of the case 210.

The first surface 236 is provided with a protrusion 239, and due to factors such as processing and assembly, there may be gaps after the planar portion 211 contacts the first surface 236 of the sealing strip 230, and the sealing effect of the sealing strip 230 may be affected by the gaps. The arrangement of the protruding portion 239 can offset and compensate for the gaps, so that the flat surface portion of the box body and the first surface 236 of the sealing strip can be in tight and seamless contact, and the sealing effect of the vacuum preservation box 200 is improved.

One of the functions of the fin 238 is that when the cover 220 is buckled with the box 210 and the evacuation is just started, the pressure difference between the storage cavity 250 and the external atmosphere is not very large, the external atmosphere may infiltrate into the storage cavity 250 through the gap between the first face 236 and the plane portion 211, and the contact position between the fin 238 and the inner side wall of the box 210 corresponds to a seal formed by the contact position between the fin 238 and the inner side wall of the box 210, so as to prevent the external atmosphere from infiltrating, thereby being helpful for improving the evacuation efficiency.

Another function of the fin 238 is that when the evacuation is completed and the fresh box 200 is in the low pressure maintenance process, the sealing strip 230 has two sealing lines, the first is the sealing contact between the first face 236 and the planar portion 211, and the arrangement of the protrusion 239 improves the sealing effect at this location; the second is the contact between the fin 238 and the inner side wall of the case 210, and even if a small amount of gas permeates through the plane portion of the case, the gas is blocked by the fin 238 and cannot enter the storage cavity 250, so that the sealing effect of the fresh-keeping case 200 is improved.

Since the stainless steel plate of the box 210 is not thick, if the sealing strip 230 directly contacts the top of the vertical wall of the box 210, the contact area for sealing is obviously too small to ensure the sealing effect, so the plane portion 211 extending horizontally outwards increases the contact area between the top of the box 210 and the first face 236 of the sealing strip 230, which is helpful for improving the sealing effect.

In the specific structure of the sealing strip 230, the second plugging portion 233, the first surface 236 for sealing contact with the planar portion 211 of the box body 210, and the fin 238 for sealing contact with the inner sidewall of the box body 210 are compact in structure, so that on one hand, plugging and assembling between the sealing strip 230 and the cover body 220 are facilitated, and on the other hand, sealing cooperation between the sealing strip 230 and the box body 210 is facilitated when the cover body 220 is buckled with the box body 210.

When the cover 220 is buckled with the box 210, the vertical portion 232 is inserted into the box 210, and the fin 238 is in contact with the inner side wall of the box 210, because the fin 238 is obliquely arranged upwards, on the one hand, the cover 220 is convenient to press down and buckle, on the other hand, when the cover 220 is pressed down, the fin 238 deforms towards one side close to the vertical portion 232 under force, so that the sealing contact area between the fin 238 and the inner side wall of the box 210 is increased, and the sealing effect of the place is further increased.

The case 210, the flat portion 211, and the curl 213 are made of the same stainless steel plate, the flat portion 211 extends horizontally from the upper edge of the side wall of the case 210 toward the outer peripheral side of the case 210, the curl 213 curls downward from the outer end side of the flat portion 211 by a certain angle and then curls upward in a direction approaching the flat portion 211, and the curl defines a cavity.

The curled edge 213 helps to improve the structural strength of the top of the case 210, and when the case 210 is taken, a person can hold the curled edge 213, thereby acting as a handle, and facilitating the taking operation.

As can be seen from fig. 5, the outer end side of the curled edge 213 is in an arc structure, the end side of the curled edge 213 is located at the inner side, and hands are not easy to contact with the end side of the curled edge 213, so that the skin can be effectively prevented from being scratched by the side of the stainless steel plate.

The outer end side of the lateral portion 231 is provided with a first slit 2311 extending horizontally, and the bottom end side of the vertical portion 2321 is provided with a second slit 2322 extending vertically.

After the cover 220 is buckled on the box 210, the first notch 2311 and the second notch 2321 provide a certain deformation space for the sealing strip 230, so that errors such as machining and assembly are eliminated, the first surface 236 of the bottom side of the transverse portion 231 can be better in fit contact with the plane portion 211, and the vertical portion 232 can be better in fit contact with the inner side wall of the box 210, so that the sealing effect is further improved.

In some embodiments of the present utility model, referring to fig. 5, the slit width of the first slit 2311 is smaller than the width of the planar portion 211. The width of the first cutout 2311 refers to the distance between the outer end side of the lateral portion 231 and the inner side of the first cutout 2311, and the width of the planar portion 211 refers to the distance between the outer end side of the planar portion 211 and the side wall of the case 210.

When the cover 220 is buckled, the transverse portion 231 abuts against the planar portion 211, if the width of the notch provided with the first notch 2311 is greater than the width of the planar portion 211, the transverse portion 231 is greatly deformed in a downward inclination after being stressed, and the structural strength of the sealing strip 230 at the transverse portion 231 is weaker, which is instead unfavorable for sealing; in contrast, if the slit width of the first slit 2311 is smaller than the width of the flat surface portion 211, the lateral portion 231 can be deformed appropriately at this point to improve the sealing effect.

In some embodiments of the utility model, the fin 238 extends obliquely upward from the bottom of the second face 237, and the fin 238 transitions in a circular arc (labeled as position P) with the bottom end surface of the vertical portion 323. Thus, when the cover 220 is pressed down and buckled, the arc transition position P plays a role in guiding, so that the cover 220 is convenient to buckle.

Meanwhile, when the fin 238 is deformed and deflected towards one side of the vertical portion 232 under the force, if the bottom of the vertical portion 232 extends beyond the fin 238, the extended extension may first abut against the inner sidewall of the box 210 to affect the deformation of the fin 238, so as to affect the sealing effect between the fin 238 and the inner sidewall of the box 210. Therefore, in this embodiment, the bottom of the fin 238 and the bottom of the vertical portion 232 are disposed on the same plane, so that this problem can be avoided.

The fin 238 has two, where a double seal is formed, further enhancing the sealing effect.

In some embodiments of the utility model, referring to FIG. 5, the top position of the second cutout 2322 is lower than the root position of the fin 238 located above. So set up, make vertical portion 232 can obtain comparatively suitable deformation here to improve sealed effect. If the height of the second cutout 2322 is set too large, the vertical portion 232 may lose reliable contact with the sidewall of the case 210, and the sealing effect may be reduced.

In some embodiments of the present utility model, the second surface 237 is provided with a groove 2371, the groove 2371 is disposed near the root of the fin 238, and the inclination direction of the groove 2371 is the same as the inclination direction of the fin 238.

One of the functions of the groove portion 2371 is that when the fin 238 is deformed and deflected toward the vertical portion 232 by force, the groove portion 2371 provides a certain space for the deformation and deflection of the fin 238, and at the same time makes the root portion of the fin 238 thinner, so that elastic deformation can be generated.

The second function of the groove 2371 is that, during the low pressure maintenance of the fresh keeping box 200, the vertical portion 232, the inner side wall of the box body 210 and the fin 238 form a gas accommodating cavity, if a small amount of gas permeates between the first face 236 and the plane 211, the permeated gas flows into the gas accommodating cavity to form a buffer, and the existence of the groove 2371 is equivalent to expanding the volume of the gas accommodating cavity, thereby helping to improve the sealing effect of the fresh keeping box 200.

For the specific arrangement of the first plugging portion 222 and the second plugging portion 233, in some embodiments of the present utility model, with continued reference to fig. 5 and 6, the first plugging portion 222 includes a plurality of slots, the second plugging portion 233 includes a plurality of slips, and the plurality of slots plug with the plurality of slips in a one-to-one correspondence, so as to achieve plugging and fixing between the first plugging portion 222 and the second plugging portion 233.

The length of slot is greater than the length of cutting, guarantees on the one hand that slot and cutting can peg graft in place, avoids leading to the condition of pegging graft in place because of reasons such as machining error, and on the other hand, the slot sets up longer, still helps reducing the materials of lid, practices thrift the cost.

The first notch 2311 is located outside of the outermost cutting. As can be seen from fig. 5, after the cover 220 is fastened, the transverse portion 231 below the external cutting is of a solid structure, so that the structural strength of the transverse portion 231 can be ensured, and the reliability of the insertion between the cutting and the slot can be ensured.

As a specific embodiment, two slots and two cutting bars are provided, respectively, and are labeled as a first slot 2221, a second slot 2222, a first cutting bar 2331, and a second cutting bar 2332, respectively. The cover 220 is provided with a first wall 223, a second wall 224, a third wall 225, a first slot 2221 formed between the first wall 223 and the second wall 224, and a second slot 2222 formed between the second wall 224 and the third wall 225. A first mating void 234 is formed between the first and second blades 2331, 2332 and a second mating void 235 is formed on the outside of the second blade 2332. After the sealing strip 230 is connected to the cover 220, the first insert 2331 is inserted into the first slot 2221, the second insert 2332 is inserted into the second slot 2222, the second wall 224 is inserted into the first insertion space 234 and located at the inner side of the plane portion 211, and the third wall 225 is inserted into the second insertion space 235 and located at the right upper portion of the plane portion 211.

When the cover 220 and the box 210 are tightly buckled under the action of the external force of the buckle 240, the cover 220 moves downward as a whole, and the part of the transverse part 231 between the third wall 225 and the plane part 211 is pressed by force, so that the sealing effect is enhanced; and the downward movement of the second wall 224 will cause the portion of the transverse portion 231 located at the lower portion of the second wall 224 to also move downward and deform, so as to drive the vertical portion 232 and the fin 238 to deform and deflect toward the inner side wall of the box 210 together, thereby improving the contact seal between the fin 238 and the inner side wall of the box 210, and further improving the sealing effect.

In some embodiments of the present utility model, the inner side surface 2333 of the inner side cutting (i.e., the first cutting 2331) is on the same vertical surface as the inner side surface 2321 of the vertical portion, and one inner wall (i.e., the first wall 223) surrounding the inner side slot (i.e., the first slot 221) extends downward to the bottom of the vertical portion 232 and abuts against the inner side surface of the vertical portion 232.

In this way, the first wall 223 is abutted against the whole inner side surface of the sealing strip 230, and when the cover 220 is pressed down and buckled, the vertical portion 232 and the first cutting 2331 are uniformly stressed, so that the contact between the vertical portion 232 and the inner side wall of the box body is abutted more closely, and the sealing effect is improved.

In some embodiments of the present utility model, the width of the slot gradually decreases from the open end of the slot to the closed end of the slot, and a wedge-shaped insertion structure is formed between the slot and the cutting, so that the insertion is more secure.

In some embodiments of the present utility model, referring to fig. 2 and 5, a buckle 240 is rotatably disposed on the cover 220, the buckle 240 has a hook 241, and the hook 241 has a bevel 242.

A clamping groove 215 is formed between the curled edge 213 and the outer side wall of the box body 210, the clamping hook 241 is clamped with the clamping groove 215, and the inclined surface part 242 abuts against the curled edge 213.

The curled structure of the curled edge 213 plays a role of being clamped with the clamping hook 241, so that the plastic cover 220 and the stainless steel box 210 are conveniently clamped and fixed through the clamping buckle 240, the reliability of the closed fresh-keeping box is improved, and the sealing fresh-keeping effect is also improved.

In some embodiments of the present utility model, the end of the curl 213 extends obliquely upward toward the direction approaching the planar portion 211 to form a curl oblique portion 214, and the slope of the curl oblique portion 214 is the same as the slope of the beveled portion 242. So arranged, the hook 241 is conveniently and smoothly clamped into the clamping groove 215 when the clamp 240 is buckled; and when the buckle 240 is opened, the hook 241 is smoothly separated from the clamping groove 215.

In some embodiments of the present utility model, referring to fig. 3 and 4, the cover 220 is provided with a suction opening 226, and the suction opening 226 is surrounded by a circumferential wall having a certain height. A vacuum valve 300 is provided at the suction port 226.

As shown in fig. 9 and 10, the vacuum valve 300 includes a cylindrical portion 310, a first flange portion 320 is provided at the bottom of the cylindrical portion 310, a second flange portion 330 is provided at the top of the cylindrical portion 310 along the circumferential direction thereof, and the first flange portion 320 and the second flange portion 330 extend horizontally toward the outside of the cylindrical portion 310, respectively.

The outer diameter of the cylinder 310 is smaller than the inner diameter of the pumping hole 226, and when the cylinder 310 is inserted into the pumping hole 226, an air flow gap is formed between the cylinder 310 and the inner wall of the pumping hole 226.

The first flanging part 320 is located at the bottom side of the air extraction opening 260, the second flanging part 330 is located at the top side of the air extraction opening 260, and the outer diameters of the first flanging part 320 and the second flanging part 330 are respectively larger than the inner diameter of the air extraction opening 260, so that the vacuum valve 300 is correspondingly clamped at the air extraction opening 260, the vacuum valve 300 is limited in the vertical direction, and the vacuum valve 300 is prevented from being separated from the air extraction opening 260.

The distance between the top surface of the first burring 320 and the bottom surface of the second burring 330 is greater than the height of the pumping hole 260.

The bottom surface of the second flanging portion 330 is provided with at least one annular groove 340. When the bottom surface of the second flange portion 330 contacts and seals with the top surface of the cover 220, if there are foreign matters such as food residues on the top surface of the cover 220, the contact tightness between the second flange portion 330 and the cover 220 is affected, and if the foreign matters are just located in the groove 340, the problem can be effectively avoided, and the contact tightness between the second flange portion 330 and the cover 220 is ensured.

In the description of the above embodiments, particular features, structures, materials, or characteristics may be combined in any suitable manner in any one or more embodiments or examples.

The foregoing is merely illustrative of the present utility model, and the present utility model is not limited thereto, and any changes or substitutions easily contemplated by those skilled in the art within the scope of the present utility model should be included in the scope of the present utility model. Therefore, the protection scope of the utility model is subject to the protection scope of the claims.
