Description

Technical Field

[0001] The present application relates to the technical field of refrigeration equipment, and in particular to a refrigerator. Background Art

[0002] At present, when a freezer is in use, the temperature inside the freezer decreases due to the refrigeration effect inside the freezer, which reduces the air pressure inside the freezer, causing the air pressure inside the freezer to be lower than the air pressure outside the freezer, resulting in negative pressure, making it difficult to open the freezer door. The formation process of the negative pressure phenomenon is roughly as follows: after the door is opened, gas exchange occurs between the inside and outside of the freezer compartment, and hot air from the outside enters the freezer compartment; after the door is closed, the temperature of the hot air in the compartment gradually decreases under the effect of refrigeration, and the pressure in the compartment decreases, resulting in a pressure difference between the inside and outside of the freezer. This causes the user to need a lot of force to open the door.

[0003] The related technology discloses a structure for reducing negative pressure in a refrigerator, comprising a refrigerator door body, a mounting groove with an Ω-shaped cross section is provided around the refrigerator door body, a plurality of air pressure balancing air guide grooves are provided in the mounting groove, and the air pressure balancing air guide grooves extend from the mounting groove to both sides of the mounting groove. A door seal is provided around the refrigerator door body, and the extension range of the air pressure balancing air guide groove is greater than the abutment width range of the refrigerator door body and the door seal. A mounting portion is provided on a surface of the door seal facing the refrigerator door body, the mounting portion is inserted in the mounting groove, and a spacing is provided between the top of the mounting portion and the bottom of the mounting groove, wing edges are provided on both sides of the mounting portion, and the two wing edges are respectively interference fit with the groove wall of the mounting groove, and the part of the air pressure balancing air guide groove located in the mounting groove passes through the abutment between the wing edge and the groove wall of the mounting groove.

[0004] An air pressure balancing air guide groove is arranged in the installation groove, and the air pressure balancing air guide groove extends inwardly through the abutment between the wing edge of the installation part and the groove wall of the installation groove, and extends outwardly through the abutment range between the door seal and the inner liner body of the refrigerator door body. When the air pressure in the refrigerator is lower than the air pressure outside the refrigerator, the door seal is squeezed, the installation part moves a certain displacement toward the groove wall of the installation groove, and the wing edge separates from the groove wall of the installation groove, so that the air pressure balancing air guide grooves on both sides of the installation groove conduct the gas inside and outside the refrigerator to achieve air pressure balance.

[0005] In the process of implementing the embodiments of the present disclosure, it is found that there are at least the following problems in the related art:

[0006] Although the related technology can avoid the generation of negative pressure, it has a complex structure and requires the coordination of multiple components to conduct the gas inside and outside the refrigerator. The process is complicated and the assembly is difficult.

[0039] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0040] At present, when a refrigerator is in use, the temperature inside the refrigerator decreases due to the refrigeration effect inside the refrigerator, which reduces the air pressure inside the refrigerator, causing the air pressure inside the refrigerator to be lower than the air pressure outside the refrigerator, generating negative pressure, making the door of the refrigerator difficult to open.

[0041] The formation process of negative pressure phenomenon is roughly as follows: after the door is opened, the air inside and outside the refrigerator is exchanged, and the hot air from the outside enters the refrigerator compartment; after the door is closed, the hot air in the compartment gradually cools down due to the refrigeration effect, and the pressure in the compartment decreases, resulting in a pressure difference between the inside and outside of the refrigerator. As a result, users need a lot of strength to open the door.

[0042] Combination Figure 1 As shown, the surface where the injection-molded cabinet opening 12 of the existing horizontal refrigerator contacts the door sealing strip is flat and airtight, and the interior of the refrigerator is well sealed. If the user needs to reopen the door of the horizontal refrigerator that has been powered on for the first time, the air pressure difference between the outside and inside of the refrigerator is large, and the door cannot be opened.

[0043] Combination Figure 2-5As shown, the embodiment of the present disclosure provides a refrigerator, including a cabinet body 10 and a door body. The upper side of the cabinet body 10 is an opening 11, and the cabinet body 10 includes a cabinet opening portion 12 arranged around the opening 11, and the cabinet opening portion 12 is provided with a breathable structure 121. The door body is arranged at the opening 11, and the door body includes a sealing strip arranged around the cabinet opening portion 12, and the sealing strip is located between the door body and the cabinet opening portion 12. Among them, the breathable structure 121 is arranged on the surface of the cabinet opening portion 12 facing the sealing strip, which is used to balance the pressure difference between the inside and outside of the refrigerator.

[0044] The refrigerator provided by the embodiment of the present disclosure is provided with a breathable structure 121 on the surface of the cabinet opening 12 facing the sealing strip, which changes the airtightness of the cabinet body 10, effectively balances the air pressure difference inside and outside the refrigerator, avoids negative pressure in the refrigerator due to temperature drop, makes the user's door opening process more labor-saving, and saves door opening time. Moreover, the structure is simple, and the conduction of the air inside and outside the refrigerator can be achieved without the cooperation of multiple components to achieve air pressure balance.

[0045] Optionally, the air-permeable structure 121 includes a convex rib 122 , and the convex rib 122 protrudes along the cabinet opening 12 toward the sealing strip.

[0046] In this way, the rib 122 is supported between the cabinet opening 12 and the sealing strip, resulting in a gap between the sealing strip near the rib 122 and the cabinet opening 12, reducing the degree of airtightness between the sealing strip and the cabinet opening 12, and allowing the air inside and outside the refrigerator to flow, effectively balancing the air pressure difference between the inside and outside of the refrigerator, avoiding negative pressure in the refrigerator due to temperature reduction, making the door opening process easier for users and saving door opening time. Moreover, the rib 122 has a simple structure, saves costs, and can achieve the conduction of air inside and outside the refrigerator and achieve air pressure balance without the cooperation of multiple components.

[0047] Optionally, ventilation holes are also provided on the rib 122 .

[0048] In this way, the pressure difference between the inside and outside of the refrigerator can be balanced faster, and the time to achieve pressure balance inside and outside the refrigerator can be shortened.

[0049] Optionally, the convex rib 122 includes a linear convex rib 123, which extends from the inner side of the cabinet opening 12 to the outer side of the cabinet opening 12. The linear convex rib 123 includes a first end 1231 and a second end 1232, wherein the first end 1231 is connected to the inner side of the cabinet opening 12, and the second end 1232 is connected to the outer side of the cabinet opening 12.

[0050] The first end 1231 of the linear convex rib 123 is connected to the inner side of the cabinet mouth 12, and the second end 1232 is connected to the outer side of the cabinet mouth 12, that is, the linear convex rib 123 connects the inner side of the cabinet mouth 12 and the outer side of the cabinet mouth 12, and the length of the linear convex rib 123 is equal to the straight-line distance from the inner side of the cabinet mouth 12 to the outer side of the cabinet mouth 12, so as to ensure that the linear convex rib 123 can conduct the air inside and outside the refrigerator.

[0051] Optionally, the width of the linear convex rib 123 is in the range of 0.4 mm to 0.6 mm, and the height of the linear convex rib 123 is in the range of 0.6 mm to 1.0 mm.

[0052] The width of the linear convex rib 123 is limited to between 0.4 mm and 0.6 mm, which can ensure a certain structural strength and save costs. The height of the linear convex rib 123 is limited to less than 1 mm, so that the refrigerator will not leak cold due to excessive height. The height of the linear convex rib 123 is limited to more than 0.6 mm, so that the refrigerator will not fail to conduct gas inside and outside due to lack of gaps due to too low height.

[0053] Optionally, the width of the linear convex rib 123 is 0.5 mm, and the height of the linear convex rib 123 is 0.8 mm.

[0054] The horizontal freezer is designed to have a surface where the injection molded cabinet opening 12 contacts the sealing strip, and then add a linear convex rib 123 with a ventilation function of 0.5 mm (rib width) * 0.8 mm (rib height), and then tested according to the following standards:

[0055] Test standard: General Electric (GE) horizontal freezer door opening force test standard "ETP 512B401 Door Opening Force with Time".

[0056] Test method: Ambient temperature 32℃, empty box, thermostat set to mid-range. Standard "ETP 512B401 Door Opening Force with Time" requires that the door of a horizontal freezer must be opened within 20 seconds when a force of 20 pounds is applied (20 pounds of vertical force is applied upward at the midpoint of the door handle).

[0057] During normal operation of a horizontal freezer, the user wishes to reopen the door immediately after the first door opening, and the waiting time after the first door closing is greater than 3 seconds.

[0058] The test is to determine the time required to reopen the door of a horizontal freezer after it has been opened for the first time. The duration of the first door opening is 10 seconds and the angle of the door is 90°.

[0059] Testing tools: dynamometer, electronic stopwatch.

[0060] Test results: The average time for reopening the door of three horizontal freezers was 1.94 seconds, 8.78 seconds, and 1.93 seconds respectively after 6 tests.

[0061] The surface design of the injection-molded cabinet opening 12 of the horizontal refrigerator in contact with the door seal is increased by 0.5mm (rib width)*0.8 (rib height) mm straight convex ribs 123 with ventilation function, which achieves the air pressure balance inside and outside the refrigerator, and the effect is very obvious.

[0062] Optionally, the convex rib 122 includes a non-linear convex rib 124, and the non-linear convex rib 124 connects the inner side of the cabinet opening 12 and the outer side of the cabinet opening 12. The non-linear convex rib 124 includes a first rib segment 1241, a second rib segment 1242, and a third rib segment 1243 located between the first rib segment 1241 and the second rib segment 1242. The first rib segment 1241 extends outward from the inner side of the cabinet opening 12 to the third rib segment 1243, and the second rib segment 1242 extends inward from the outer side of the cabinet opening 12 to the third rib segment 1243. The connection between the first rib segment 1241 and the third rib segment 1243 forms a first bend 1244, and the connection between the second rib segment 1242 and the third rib segment 1243 forms a second bend 1245.

[0063] In this way, the inner side and the outer side of the cabinet mouth 12 are connected by the first rib segment 1241, the second rib segment 1242 and the third rib segment 1243. The connection between the first rib segment 1241 and the third rib segment 1243 forms a first bend 1244, and the connection between the second rib segment 1242 and the third rib segment 1243 forms a second bend 1245. This arrangement can reduce the amount of cold leakage of the refrigerator, and improve the sealing of the refrigerator while balancing the air pressure.

The height of the non-linear rib 124 is limited to less than 1 mm, so that the refrigerator will not leak cold due to excessive height.

[0068] In this way, the groove 125 is located between the cabinet opening 12 and the sealing strip, the sealing strip and the cabinet opening 12 are less airtight, and the air inside and outside the refrigerator is conducted through the groove 125, effectively balancing the air pressure difference inside and outside the refrigerator, avoiding negative pressure in the refrigerator due to temperature reduction, making the user's door opening process more labor-saving and saving door opening time. Moreover, the structure of the groove 125 is simple, cost-saving, and the conduction of the air inside and outside the refrigerator and the balance of air pressure can be achieved without the cooperation of multiple components.
