Description

Technical Field

[0001] This invention relates to the field of freezer technology, specifically a novel freezer. Background Technology

[0002] Refrigerators are generally used in shops, supermarkets, shopping malls, and other places where refrigerated goods are stored. Currently, there are three main types of upright display refrigerators on the market: top-mounted, bottom-mounted, and air-curtain refrigerators. However, all three types have certain drawbacks. When using a top-mounted refrigerator, electrical components are placed on top of the cabinet or copper pipes protrude from the cabinet. For example, in a high-preservation refrigerator with a top-mounted sterilization system disclosed in Chinese Patent CN108469142A, the sterilization system is located at the top of the cabinet, making it difficult to access in areas with height restrictions, and hindering maintenance and repair. Similarly, the bottom-mounted upright refrigerator disclosed in Chinese Patent CN106595175A lacks a light box, and adding one would be costly, and installation is not possible in some areas with height restrictions. Furthermore, the air-curtain refrigerator disclosed in Chinese Patent CN113503666A, an open-type air-curtain refrigerator, has high operating costs and consumes a lot of electricity. Therefore, developing a refrigerator that integrates the advantages of various upright display refrigerators to address different usage scenarios would meet the needs of different customers. Summary of the Invention

[0003] In view of the aforementioned technical problems that exist in existing upright display freezers on the market, the technical solution adopted by this invention to solve these technical problems is as follows:

[0004] A novel refrigerator includes a cabinet, an electrical unit, a frameless glass door, and a light box. The cabinet has a refrigeration area, a first installation area, a second installation area, a third installation area, and door hinges located on the upper and lower sides of the cabinet. The frameless glass door is hinged to the front side of the cabinet via the door hinges. The light box is located in front of the first installation area. The first and third installation areas are located above the refrigeration area, and the second installation area is located below the refrigeration area. The electrical unit is installed in the first installation area and / or the second installation area. When the electrical unit is installed in the first installation area, the wiring and copper pipes of the electrical unit can be concealed in the third installation area. The frameless glass door has a door frame strip connected to the door hinges and a door heating wire. The door hinges are hollow and allow the door heating wire to pass through.

[0005] To increase the internal space of the freezer, frame columns are provided on both sides of the refrigeration area. The frame columns are designed to be vertical or inclined.

[0006] To increase the internal space of the freezer, the frame columns are equipped with shelf racks, and the shelf racks are equipped with support arms connected to the two frame columns respectively, and crossbeams set on the two support arms.

[0007] To improve the refrigeration effect of the freezer, the electrical components include a condenser device disposed in the first installation area and / or the second installation area, and return air vents are provided at the top and / or bottom of the inner side of the refrigeration area.

[0008] To enhance the appearance of the freezer, a light box light is installed inside the light box, shelf lights are installed on the shelf racks, and an inner ceiling light is installed inside the refrigeration area.

[0009] To improve the closing effect of the frameless glass door, the frameless glass door is provided with inner glass and outer glass. The inner glass and the outer glass are provided with a main frame on the outside. A first flexible sealing strip is provided on one side of the main frame and a second flexible sealing strip is provided on the other side of the main frame. The first flexible sealing strip can cooperate with the other first flexible sealing strip to make the two frameless glass doors in a sealed state.

[0010] To improve the airtightness of the freezer, side panels are provided on both sides of the cabinet. The second flexible sealing strip is set between the side panel and the frameless glass door. Each of the second flexible sealing strips can cooperate with the side panel to keep the frameless glass door and the side panel in a sealed state.

[0011] To improve the airtightness of the freezer, the main frame is provided with a first mounting groove and a second mounting groove. The first flexible sealing strip is provided with a first sealing strip connecting part that cooperates with the first mounting groove, and the second flexible sealing strip is provided with a second sealing strip connecting part that cooperates with the second mounting groove.

[0012] To prevent fogging on the surface of the frameless glass door and to improve the closing effect of the frameless glass door, the housing is provided with a fixed seat. The door hinge includes a door hinge connector connected to the door frame strip and a hollow door shaft assembly that allows the door heating wire to pass through. One end of the door shaft assembly is connected to the door hinge connector and the other end passes through the fixed seat. An elastic reset part and a fixing component are sleeved on the outside of the door shaft assembly.

[0013] In order to realize the limiting and stopping function of the frameless glass door, the door hinge is also provided with a limiting component, which includes a first connecting part connected to the fixed base and a second connecting part connected to the door hinge connector.

[0014] The beneficial effects of this invention are as follows:

[0015] 1. Conventional top-mounted cabinets have the electrical unit mounted on the top of the cabinet, with copper pipes protruding to the top, taking up space and affecting transportation in areas with height restrictions. In contrast, the electrical unit of this invention is installed in the first installation area, the second installation area, or both. The wiring and copper pipes of the electrical unit can be hidden in the third installation area, effectively utilizing space, avoiding the impact of height restrictions during transportation, and facilitating maintenance and repair. Compared with conventional bottom-mounted cabinets, this invention has a light box on the front side of the first installation area, which can improve the appearance of the freezer and avoid the cost of later installation. Compared with conventional air curtain cabinets, the appearance of this invention adopts an air curtain cabinet design and a frameless glass door, which can increase the effective viewing area. At the same time, the frameless glass door can be closed to prevent heat loss and reduce energy consumption.

[0016] 2. This invention utilizes a hollow-designed door hinge, allowing the door heating wire to run from the center of the hinge. The door heating wire heats the hinge to remove fog from the glass door, effectively preventing exposed electronic wires. When using frameless glass doors, it will not affect the appearance.

[0017] 3. This invention features the appearance of an air curtain cabinet, is more energy-efficient than an air curtain cabinet, and combines the functions of a top-mounted cabinet and a bottom-mounted cabinet. Its appearance is simple yet sophisticated. It allows for differentiated competition among top-mounted cabinets, bottom-mounted cabinets, and air curtain cabinets, flexibly adapting to the diverse needs of different customers, making it highly competitive in the market.

[0018] 4. This invention features an elastic reset part and a fixing component sleeved on the outside of the door hinge assembly. The elastic reset part is used to cause the door hinge connector to spring back and reset. Since the door hinge connector is connected to the frameless glass door, it can drive the frameless glass door to achieve an automatic spring-back effect. By setting a limiting component between the door hinge connector and the fixing seat, when the frameless glass door rotates along the door hinge assembly and drives the limiting component to rotate to a certain angle and reach the stop point, the door hinge connector stops resetting, thereby stopping the frameless glass door from moving and realizing the limiting and stopping function. It has the advantages of stable structure and low cost.

[0019] 5. The present invention forms a receiving cavity between the door frame strip and the frameless glass door. A heating wire is provided in the receiving cavity to heat the space inside the frameless glass door to prevent the generation of moisture. When the two frameless glass doors are closed, the first flexible sealing strip of one door abuts against the other to seal the gap between the two frameless glass doors. At the same time, the second flexible sealing strip abuts against the side panel of the freezer, sealing the gap between each frameless glass door and the side panel of the freezer. When the two frameless glass doors are open, the second flexible sealing strip elastically deforms according to the opening of the frameless glass doors, so that the free end of the second flexible sealing strip always abuts against the side panel of the freezer to seal the gap between the frameless glass doors and the side panel of the freezer. It has the advantages of simple structure and good sealing performance. Attached Figure Description

[0032] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0033] A novel refrigerator includes a cabinet body 1, an electrical unit 19, a frameless glass door 2, and a light box 5. The cabinet body 1 has a refrigeration area 6, a first mounting area 7, a second mounting area 8, a third mounting area 9, and door hinges 21 located on the upper and lower sides of the cabinet body 1. The frameless glass door 2 is hinged to the front side of the cabinet body 1 via the door hinges 21. The light box 5 is located in front of the first mounting area 7. The first mounting area 7 and the third mounting area 9 are located on the upper side of the refrigeration area 6, and the second mounting area 8 is located on the lower side of the refrigeration area 6. The electrical unit 19 is installed on the first mounting area 7 and / or the second mounting area 8. When the electrical unit 19 is installed on the first mounting area 7, the wiring and copper pipes of the electrical unit 19 can be hidden in the third mounting area 9. The frameless glass door 2 has a door frame strip 3 connected to the door hinges 21 and a door heating wire 4. The door hinges 21 are hollow and allow the door heating wire 4 to pass through. Conventional top-mounted cabinets have the electrical unit mounted on the top of the cabinet, with copper pipes protruding to the top, taking up space and affecting transportation in height-restricted areas. In contrast, the electrical unit of this invention is installed in the first installation area, the second installation area, or both. The wiring and copper pipes of the electrical unit can be hidden in the third installation area, effectively utilizing space, avoiding the impact of height restrictions during transportation, and facilitating maintenance and repair. Compared to conventional bottom-mounted cabinets, this invention has a light box on the front side of the first installation area, which improves the appearance of the freezer and avoids the cost of later installation. Compared to conventional air curtain cabinets, the appearance of this invention adopts an air curtain cabinet design and a frameless glass door, which increases the effective viewing area. At the same time, closing the frameless glass door can prevent heat loss and reduce energy consumption.

[0034] Furthermore, the third installation area is located behind the first installation area. The second installation area can be used to install the electrical unit, or it can be used as a separate cabinet without installing the electrical unit, thereby improving the space utilization of the freezer. The freezer can be equipped with casters and support legs according to customer needs. Piping and cable routing channels are reserved on the rear side of the cabinet. The wiring and copper pipes of the electrical unit are connected to other components from the rear of the cabinet through the third installation area. This arrangement facilitates maintenance and repair.

[0035] This invention utilizes a hollow-designed door hinge, allowing the door heating wire to run through the center of the hinge. The heating wire removes fog from the glass door by heating the hinge, effectively preventing exposed electronic wires. When using frameless glass doors, it does not affect the appearance.

[0036] This invention features the appearance of an air curtain cabinet, is more energy-efficient than an air curtain cabinet, and combines the functions of a top-mounted cabinet and a bottom-mounted cabinet. Its appearance is simple yet sophisticated. It allows for differentiated competition among top-mounted cabinets, bottom-mounted cabinets, and air curtain cabinets, flexibly adapting to the diverse needs of different customers, making it highly competitive in the market.

[0037] like Figure 1 , Figure 2 and Figure 3 The illustration shows a novel type of freezer, in which skeletal columns 61 are provided on both sides of the refrigeration compartment 6. These skeletal columns 61 can be vertically or inclined. Compared to existing freezers with a central beam, the vertically designed skeletal columns of this invention, combined with the frameless glass door, create a more transparent appearance and utilize more internal space. The inclined skeletal columns align with the buyer's line of sight, and together with the shelves, allow for a more layered presentation of goods displayed inside the freezer, creating a differentiated visual experience.

[0038] like Figure 1 , Figure 2 and Figure 3 The illustrated novel refrigerator features a shelf unit 16 mounted on the frame columns 61. Each shelf unit 16 has support arms 161 connected to two of the frame columns 61, and crossbeams 162 mounted on the two support arms 161. This design allows for the installation of support panels or glass on the shelf unit for placing food or beverages, thanks to the two support arms and crossbeams. Furthermore, the support arms can be angled upwards, which not only supports the goods but also allows the upward-angled shelf unit to align with the buyer's line of sight.

[0039] like Figure 1 , Figure 2 and Figure 3 The illustration shows a novel type of freezer. The electrical components 19 include a condenser 17 disposed in the first mounting area 7 and / or the second mounting area 8. Return air vents 18 are provided at the top and / or bottom of the inner side of the refrigeration compartment 6. Furthermore, the condenser can be disposed in the first mounting area, the second mounting area, or both. Return air vents communicating with the condenser are provided according to the condenser's configuration. The design of the return air vents at the top and bottom of the inner side of the refrigeration compartment gives the freezer an appearance similar to an air curtain freezer, enabling the freezer to maintain a suitable internal temperature. Combined with the frameless glass door, this helps maintain the temperature of the refrigeration compartment and reduces power consumption.

[0040] like Figure 1 , Figure 2 and Figure 3 The illustration shows a new type of freezer where the lightbox 5 has a lightbox light inside, the shelf racks 16 have shelf lights, and the refrigeration compartment 6 has an inner ceiling light. This design allows for the on / off control of the lightbox lights, ceiling lights, and shelf lights as needed, and offers a more visually striking appearance compared to traditional bottom-mounted freezers.

[0041] like Figure 1 , Figure 2 , Figure 3 and Figure 6The illustrated novel refrigerator features a frameless glass door 2 with an inner glass panel 11 and an outer glass panel 12. A main frame 13 is provided on the outer sides of both the inner and outer glass panels 11 and 12. A first flexible sealing strip 14 is provided on one side of the main frame 13, and a second flexible sealing strip 15 is provided on the other side. One of the first flexible sealing strips 14 can cooperate with the other to seal the two frameless glass doors 2. Since the door frame strip is located on the outer sides of the inner and outer glass panels, a transparent door frame is provided between them to reduce heat loss. A door frame sealing strip is connected to the main frame, which helps prevent heat loss and reduce energy consumption. Furthermore, a handle is provided on the outer glass panel for easy opening and closing of the frameless glass door.

[0042] like Figure 1 , Figure 2 , Figure 3 and Figure 6 The illustrated novel freezer has side panels 10 on both sides of the cabinet 1. A second flexible sealing strip 15 is disposed between the side panel 10 and the frameless glass door 2. Each of the second flexible sealing strips 15 can cooperate with the side panel 10 to maintain a sealed state between the frameless glass door 2 and the side panel 10. Furthermore, to improve the transparency of the freezer's appearance, the frameless glass door is located inside the end face of the side panel. When the frameless glass door is closed, when the freezer is viewed from the side, because the frameless glass door is set inside the main frame, the frameless glass door does not protrude outwards, and the frameless glass door and the cabinet present an integrated appearance, resulting in a simpler and more elegant look.

[0043] like Figure 6 , Figure 7 , Figure 8 and Figure 9 The novel refrigerator shown has a main frame 13 with a first mounting groove 131 and a second mounting groove 132. A first flexible sealing strip 14 has a first sealing strip connecting portion 141 that mates with the first mounting groove 131, and a second flexible sealing strip 15 has a second sealing strip connecting portion 151 that mates with the second mounting groove 132. This design allows the first mounting groove to connect tightly with the first sealing strip connecting portion, improving the sealing performance between the main frame and the first flexible sealing strip, reducing heat loss, and lowering energy consumption. Similarly, the second mounting groove can connect tightly with the second sealing strip connecting portion, improving the sealing performance between the side panel and the second flexible sealing strip, reducing heat loss, and lowering energy consumption.

[0044] like Figure 8As shown, the first flexible sealing strip 14 includes a first sealing strip connecting part 141, a first covering part 142, and a first sealing part 143 connected in sequence. The first sealing strip connecting part 141 can be inserted into the first mounting groove 131 so that the first flexible sealing strip 14 can be assembled on the main frame 13. With this design, the first flexible sealing strip 14 can be detachably connected to the main frame 13. When the first flexible sealing strip 14 is damaged or aged, it can be replaced.

[0045] The first covering part 142 is used to cover the part where the first sealing strip connecting part 141 is connected to the first mounting groove 131, so that the first soft sealing strip 14 and the main frame 13 look like a whole without any connecting gaps, which is more aesthetically pleasing.

[0046] The first sealing part 143 is provided with a first sealing end face. The first sealing part 143 cooperates with the first sealing end face of another first sealing part 143 through the first sealing end face. Specifically, the first sealing end face of the first sealing part 143 abuts against the first sealing end face of another first sealing part 143. Due to the pressure of air and the surface tension of water, when two smooth flat objects are stacked together, they will be firmly "stuck" together due to air pressure. The first soft sealing strip is made of plastic material. Plastic materials are non-absorbent and airtight, so moisture in the air easily condenses on its surface and causes adhesion. This allows the two first sealing parts to be sealed by the cooperation between the first sealing end faces.

[0047] To further improve the sealing effect, there are two first sealing end faces, which are respectively located on opposite sides of the corresponding first sealing part 143. This design allows the first sealing end faces on the two first sealing parts 143 to abut against each other and be in a sealed state when the two frameless glass doors 2 are closed, thus improving the sealing performance. In addition, each of the first sealing parts 143 is rectangular in shape, which facilitates manufacturing and makes it easy for the two first sealing parts 143 to cooperate with each other.

[0048] like Figure 8As shown, the first sealing strip connecting part 141 in this embodiment includes two elastic snap-fit ​​strips 1411 that are inclined inward from bottom to top towards the central axis of the first covering part 142. The first mounting groove 131 corresponds to the elastic snap-fit ​​strips 1411. When the first soft sealing strip 14 is assembled onto the main frame 13, the user can first snap one side of the elastic snap-fit ​​strip 1411 into the corresponding first mounting groove 131, and then snap the other elastic snap-fit ​​strip 1411 into the corresponding first mounting groove 131. Each elastic snap-fit ​​strip 1411 has a hook 1412 on its free end. Each first mounting groove 131 has a limiting protrusion 1311 that cooperates with the hook 1412 at its opening. The limiting protrusion 1311 abuts against the hook 1412 to restrict the elastic snap-fit ​​strip 1411 within the first mounting groove 131. The structure is simple and the operation is convenient.

[0049] like Figure 9 As shown, the second flexible sealing strip 15 includes a second sealing strip connecting part 151, a second covering part 152, and a second sealing part 153 connected in sequence. The main frame 13 is provided with a second mounting groove 132 that is adapted to connect with the second sealing strip connecting part 151. With this design, the second flexible sealing strip 15 can be detachably connected to the main frame 13. When the second flexible sealing strip 15 is damaged or aged, it can be replaced.

[0050] The second covering part 152 is used to cover the part where the second sealing strip connecting part 151 connects to the second mounting groove 132, so that the second soft sealing strip 15 and the main frame 13 look like a whole without any connecting gaps, which is more aesthetically pleasing.

[0051] There are two second sealing parts 153, which are spaced apart on the second covering part 152. The two second sealing parts 153 cooperate with the side panel 10 of the freezer to make the second sealing parts 153 and the side panel 10 of the freezer in a sealed state. Specifically, when the frameless glass door 2 is closed relative to the freezer body, the ends of the two second sealing parts 153 abut against the side panel 10 of the freezer to close the gap between the frameless glass door 2 and the side panel 10 of the freezer.

[0052] When the frameless glass door 2 is open relative to the freezer body, the two second sealing parts 153 undergo elastic deformation and bend as the frameless glass door 2 is opened, thereby keeping the ends of the second sealing parts 153 in a state of contact with the side panel of the freezer.

[0053] Two second sealing parts 153 are used. When the second sealing part 153 near the freezer body is damaged, the second sealing part 153 away from the freezer body can still play a sealing role, thus improving the sealing performance.

[0054] like Figure 2 , Figure 4 and Figure 5 The present invention discloses a novel type of refrigerator, wherein a door heating wire 4 is provided between the door frame strip 3 and the frameless glass door 2, a fixing seat 29 is provided on the cabinet body 1, and the door hinge 21 includes a door hinge connector 20 connected to the door frame strip 3 and a hollow door pivot assembly 211 through which the door heating wire 4 can pass. One end of the door pivot assembly 211 is connected to the door hinge connector 20 and the other end passes through the fixing seat 29. An elastic reset part 212 and a fixing component 213 are sleeved on the outside of the door pivot assembly 211. The present invention utilizes a hollow door pivot assembly, allowing the door heating wire to run from the center of the door pivot assembly. The door heating wire heats the door pivot assembly to remove fog from the frameless glass door, effectively avoiding exposure of the door heating wire. When a frameless glass door is used, it will not affect the appearance. By providing an elastic reset part and a fixing component on the outside of the door pivot assembly, the elastic reset part is used to cause the door hinge connector to spring back to its original position. Since the door hinge connector is connected to the frameless glass door, the frameless glass door can achieve an automatic spring-back effect.

[0055] like Figure 2 , Figure 4 and Figure 5 The novel refrigerator shown has a limiting component 214 on the door hinge 21. The limiting component 214 includes a first connecting part 2141 connected to the fixed base 29 and a second connecting part 2142 connected to the door hinge connector 20. With this design, the frameless glass door rotates along the door hinge assembly. The second connecting part is connected to the door hinge connector and drives the first connecting part to rotate as the frameless glass door rotates. Furthermore, the acute angle between the direction of the force and the direction of the velocity of the driven part forms the pressure angle, and the complementary angle of the pressure angle is the transmission angle. When the transmission angle is zero, the effective rotational torque of the driving force on the driven part is zero. Since the pressure angle is 90° when the transmission angle is zero, the force or torque on the driven part is zero. At this time, the driving part cannot drive the driven part to work, and the mechanism is at a stop point. When the frameless glass door is opened to a certain angle, the limiting assembly will restrict the frameless glass door from continuing to move. After releasing the hand, the frameless glass door will automatically stop at a certain movement angle. When the frameless glass door rotates, the door hinge assembly drives the elastic reset part to generate torque. When the frameless glass door is closed with a little force, the elastic reset part resets and rebounds.

[0056] Furthermore, such as Figure 2 , Figure 4 and Figure 5The novel refrigerator shown has a mounting base 29 with a mounting base opening. The door hinge assembly 211 includes a door hinge connecting part 2111 connected to the door hinge connector 20 and a door hinge body 2112 passing through the mounting base opening. The end of the door hinge body 2112 abuts against the mounting assembly 213. With this design, since the door hinge connecting part is connected to the door hinge connector, when the door rotates, the door hinge connector connected to the door rotates the door hinge connecting part, thereby rotating the door hinge body. The end of the door hinge body abuts against the mounting assembly, causing the elastic reset part connected to the mounting assembly to twist and generate torque. When the door is closed with slight force, the elastic reset part resets and rebounds, causing the mounting assembly to rotate the door hinge body in the direction of door closing, thus closing the door via the door hinge connecting part.

[0057] like Figure 2 , Figure 4 and Figure 5 The novel refrigerator shown includes a door hinge assembly 211 further comprising a door hinge engaging portion 2113 disposed between the door hinge connecting portion 2111 and the door hinge body 2112. The outer diameter of the door hinge engaging portion 2113 is larger than the outer diameter of the door hinge connecting portion 2111. A first gasket 2114 is sleeved on the outer side of the door hinge body 2112, and the first gasket 2114 is disposed between the door hinge engaging portion 2113 and the fixing seat opening. Furthermore, because the outer diameter of the door hinge engaging portion is larger than the outer diameter of the door hinge body, the door hinge engaging portion can be positioned between the bottom of the door hinge connector and the fixing seat opening. The inner diameter of the first gasket is smaller than the outer diameter of the door hinge engaging portion, and the outer diameter of the first gasket is larger than the outer diameter of the fixing seat opening. This allows the first gasket to abut against the bottom of the door hinge engaging portion and the upper side of the fixing seat opening, thereby ensuring the stability of the door hinge assembly and preventing it from wobbling up and down.

[0058] like Figure 2 , Figure 4 and Figure 5 The novel refrigerator shown includes a door hinge assembly 211 further comprising a door hinge sleeve 2115 disposed between the outer side of the door hinge body 2112 and the inner side of the fixing seat opening. The door hinge sleeve 2115 extends from the fixing seat opening toward the fixing assembly 213, and the elastic reset part 212 is sleeved on the outer side of the door hinge sleeve 2115. With this design, the door hinge sleeve reduces wear between the door hinge body and the fixing seat opening during rotation, and the elastic reset part, sleeved on the outer side of the door hinge sleeve, reduces wear on the door hinge body caused by the elastic reset part.

[0059] like Figure 2 , Figure 4 and Figure 5The novel refrigerator shown has a first fixing hole 191 on the fixing base 29 and a second fixing hole 2133 on the fixing assembly 213. One end of the elastic reset part 212 is housed in the first fixing hole 191, and the other end of the elastic reset part 212 is housed in the second fixing hole 2133. With this design, when the door rotates, the door hinge connector connected to the door rotates the door shaft connector, thereby rotating the door shaft body. The door shaft body causes the fixing assembly to rotate, which in turn causes the other end of the elastic reset part in the second fixing hole to twist, generating torque. When the door closes, the other end of the elastic reset part resets, allowing the door to automatically spring back.

[0060] like Figure 2 , Figure 4 and Figure 5 The novel refrigerator shown includes a fixing component 213 comprising a first fixing member 2131 whose end abuts against the elastic reset part 212, and a second fixing member 2132 located between the first fixing member 2131 and the end of the door hinge body 2112. The second fixing hole 2133 includes a fixing hole A21331 provided on the first fixing member 2131 and a fixing hole B21332 provided on the second fixing member 2132. A second gasket 2135 is provided between the second fixing member 2132 and the end of the door hinge body 2112. With this design, one end of the first fixing member abuts against the elastic reset part, further stabilizing the elastic reset part. The second fixing member is positioned between the first fixing member and the end of the door hinge body, providing a limiting effect. Furthermore, since one end of the elastic reset part is housed within the first fixing hole, and the other end is connected to the fixing hole B through fixing hole A, when the door hinge body rotates, the end of the door hinge body drives the second fixing member to rotate, and the elastic reset part simultaneously drives the first fixing member to rotate, thus generating torque. The second washer can better engage between the second fixing member and the end of the door hinge body, preventing the second fixing member from loosening. When the door hinge body rotates, the end of the door hinge body drives the second fixing member to rotate, and the elastic reset part simultaneously drives the first fixing member to rotate, thus generating torque.

[0061] like Figure 2 , Figure 4 and Figure 5The novel refrigerator shown includes a fixing assembly 213 further comprising a connecting shaft 2134. One end of the connecting shaft 2134 is connected to the outside of the fixing hole B 21332, and the other end extends to the outside of the fixing hole A 21332. The other end of the connecting shaft 2134 is provided with a third fixing hole 21333 through which the elastic reset part 212 passes. With this design, one end of the connecting shaft is connected to the outside of the fixing hole B, and the other end extends to the outside of the fixing hole A. The connecting shaft allows the first fixing member and the second fixing member to rotate simultaneously. The third fixing hole at the other end of the connecting shaft allows the elastic reset part to pass through, creating a limiting effect that makes the elastic reset part more stable. When the elastic reset part twists, it is further fixed, reducing the possibility of the other end of the elastic reset part coming loose from the fixing holes B and A.

[0062] like Figure 12 As shown, each of the aforementioned door frame strips 3 is provided with a door frame strip mounting groove 31 for assembling the inner glass 11 and the outer glass 12. Each of the aforementioned door frame strips 3 and the frameless glass door 2 forms a receiving cavity 32 for accommodating the heating component. The door frame strip of the present invention forms a receiving cavity with the frameless glass door, and a heating wire capable of heating the space inside the frameless glass door is provided in the receiving cavity to prevent the generation of moisture. When both frameless glass doors are in the closed state, the first flexible sealing strip of one abuts against the first flexible sealing strip of the other. The second flexible sealing strip seals the gap between the two frameless glass doors. Simultaneously, the second flexible sealing strip abuts against the side panel of the freezer, sealing the gap between each frameless glass door and the side panel. When the two frameless glass doors are open, the second flexible sealing strip elastically deforms according to the opening of the doors, ensuring that its free end remains against the side panel of the freezer, thus sealing the gap between the frameless glass doors and the side panel. This design offers advantages such as simple structure and good sealing performance.

[0063] like Figure 6 , Figure 10 and Figure 11 As shown, the frameless glass door is also connected to two second sub-frames 23. Each main frame 13 has auxiliary frames 24 at both ends. The connection between the main frame 13 and each auxiliary frame 24 is provided with a first mounting hole 135. A connecting bracket 136 is adapted to be connected to the first mounting hole 135. The connecting bracket 136 can be adapted to be connected to the second sub-frame 23. Each door frame strip 3 has a connecting port 33 at both ends that can be connected to the corresponding two auxiliary frames 24. The receiving cavity 32 is located between the door frame strip 3 and the second sub-frame 23.

[0064] The auxiliary frame 24 is provided with two guide protrusions 242, which are located on both sides of the connecting bracket 136. The two guide protrusions 242 can guide the connecting bracket 136 to slide accurately into the first mounting hole 135, reducing the difficulty of assembly.

[0065] The two guide protrusions 242 can prevent the connecting bracket 136 from wobbling from side to side and can further fix the connecting bracket 136.

[0066] like Figure 8 , Figure 9 and Figure 11 As shown, in this embodiment, the main frame 13 is provided with first positioning portions 134 on both sides of the outer sidewalls away from the inner glass 11 and the outer glass 13. The main frame 13 is provided with a main mounting surface 133. The first positioning portions 134 extend outward in a direction away from the main mounting surface 133. The inner side of each of the first positioning portions 134 abuts against the side of the inner glass 11 or the outer glass 13. When the inner glass 11 or the outer glass 13 is assembled on the main mounting surface 133, one side of the inner glass 11 or the outer glass 13 can abut against the inner side of the corresponding first positioning portion 134. The first positioning portion 134 can play a positioning role, so that the inner glass 11 or the outer glass 13 can be accurately fixed and installed on the main frame 13.

[0067] like Figure 8 , Figure 9 and Figure 11 As shown, in this embodiment, the auxiliary frame 24 is provided with second positioning portions 243 on both sides of the outer side wall away from the inner glass 11 and the outer glass 13. The second positioning portions 243 extend outward in a direction away from the main mounting surface 133. The inner side of each of the second positioning portions 133 abuts against the side of the inner glass 11 and the outer glass 13. The second positioning portions 243 and the first positioning portions 134 are correspondingly provided, and the two are integrally formed structures.

[0068] Specifically, the second positioning part has the same outer contour as the first positioning part, and each of the second positioning parts and the corresponding first positioning part forms an integral positioning part. When the inner glass 11 and the outer glass 13 are assembled on the main frame 13, one side of the inner glass 11 and the outer glass 13 can abut against the inner side of the positioning part, that is, the inner side of the second positioning part and the inner side of the first positioning part, so as to position and assemble the inner glass 11 and the outer glass 13 on the main frame 13. With this design, the glass door panel can be quickly positioned and installed on the main frame 13, improving assembly efficiency. The positioning part can also play a role in shielding the side of the glass and shielding the gap between the glass and the main frame 13 and the auxiliary frame. Furthermore, the second positioning part 243 and the first positioning part 134 are integrally formed, making the door panel positioning part appear to have no connection gap, which looks more aesthetically pleasing.

[0069] like Figure 8 and Figure 9 As shown, the width of the first positioning part 134 is r, and the thickness of the glass is R, where r and R satisfy: r≤R; preferably, the outer contour of the second positioning part is the same as that of the first positioning part, that is, the width of the positioning part is r, and the thickness of the glass is R, where r and R satisfy: r≤R, to avoid the width of the positioning part exceeding the thickness of the glass, so that the positioning part extends beyond the glass.

[0070] Specifically, in this embodiment, each of the second sub-frames 23 has a second mounting hole at both ends. One end of the connecting bracket 136 extends into the first mounting hole 135, and the insertion part 161 at the other end of the connecting bracket 16 extends into the second mounting hole. Both sides of the connecting bracket 136 have insertion parts 1361, which are respectively glued to the first mounting hole 135 and the second mounting hole. Compared with the old design where the connecting brackets are threaded to the main frame and the second sub-frames using screws and other parts, the connecting brackets in this application are glued to the main frame and the second sub-frames respectively, which effectively reduces the number of parts and eliminates the need to open threaded holes on the connecting brackets, the main frame, and the second sub-frames, making assembly convenient and effectively improving assembly efficiency.

[0071] Specifically, in this embodiment, the main frame 13, the second sub-frame 23, the door frame strip 3, and the auxiliary frame 24 are all made of transparent material; the main frame 13, the second sub-frame 23, the door frame strip 3, and the auxiliary frame 24 are combined to form a transparent door frame. After the two glass door panels are installed on the main frame, the entire frameless door looks transparent, making the freezer door look frameless, more beautiful, less bulky, and more upscale.

[0072] The auxiliary frame 24 is provided with an auxiliary frame mounting surface 241, and the auxiliary frame 24 is provided with a third mounting groove 244 for installing a flexible sealing strip. The multiple third mounting grooves 244 can respectively connect with the corresponding first mounting groove 131 and second mounting groove 132 to form a flexible sealing strip mounting groove. By assembling the corresponding first flexible sealing strip 14 and second flexible sealing strip 15 through the corresponding flexible sealing strip mounting groove, the frameless door looks more beautiful.

[0073] like Figure 10 and Figure 11As shown, in this embodiment, each of the auxiliary frame 24 is detachably connected to the end of the main frame 13. During assembly, the auxiliary frame is first assembled at both ends of the main frame, and then the second sub-frame is assembled between the two main frames through connecting brackets to form an overall door frame. Then, glass is assembled on both sides of the door frame to hide the main frame and the second sub-frame. Then, the first sub-frame is assembled at both ends of the door frame with glass, specifically by inserting the free end of the auxiliary frame into the connection port on the end of the door frame strip, thereby completing the installation of the entire frameless door. The design of detachable connection between the auxiliary frame and the main frame reduces the length of the main frame, thereby reducing the production difficulty and transportation volume of the main frame, and also reducing the assembly difficulty of the door frame.

[0074] Furthermore, the auxiliary frame 24 and the connecting corner bracket 136 are integrally formed, which can reduce the assembly cost of the auxiliary frame and the connecting corner bracket and ensure the overall structural strength between the auxiliary frame and the connecting corner bracket.

[0075] Specifically, when the auxiliary frame 24 in this embodiment is assembled on the main frame 13, each of the guide protrusions 242 is connected to the main frame 13; specifically, the end face of the auxiliary frame and the end face of each of the guide protrusions are respectively glued to the end face of the main frame. This design can effectively increase the bonding area between the auxiliary frame and the main frame, further improve the stability of the connection between the auxiliary frame and the main frame, and improve the structural strength between the auxiliary frame and the connecting corner bracket.

[0076] The embodiments of the present invention are as follows:

[0077] The electrical unit 19 is installed in the first installation area 7. Since the third installation area 9 is located behind the first installation area 7, the wiring and copper pipes of the electrical unit 19 can be hidden in the third installation area 9, which can effectively utilize space and avoid the impact of transportation height restrictions. The rear side of the enclosure 1 is reserved for pipe and cable routing. The wiring and copper pipes of the electrical unit 19 are connected to other components through the third installation area 9 from the rear side of the enclosure 1, which does not affect the appearance and is conducive to maintenance and repair. The upper and lower sides of the enclosure 1 are respectively provided with door frame strips 3 for fixing the frameless glass door 2. The door frame strips 3 are connected to the door hinges 21, and a door heating wire 4 is provided between the door frame strips 3 and the frameless glass door 2. When the frameless glass door 2 is rotated, the frameless glass door 2 rotates along the door hinges 21 through the door frame strips 3. The door heating wire 4 can prevent frost or fogging on the surface of the frameless glass door 2, improving the transparency of the frameless glass door 2.

[0078] The frameless glass door 2 has an inner glass 11 and an outer glass 12. A main frame 13 is provided on the outer sides of the inner glass 11 and outer glass 12, and a second flexible sealing strip 15 is connected to the main frame 13. The main frame 13 has a first mounting groove 131, and the second flexible sealing strip 15 has a connecting part 141 that mates with the first mounting groove 131. Side panels 10 are provided on both sides of the enclosure 1, and the second flexible sealing strip 15 connects the side panels 10 to the frameless glass door 2. The frameless glass door makes the interior of the enclosure more transparent and the appearance more concise. The main frame 13, through the first mounting groove 131, mates with the connecting part 141 on the second flexible sealing strip 15, which improves the sealing performance between the frameless glass door 2 and the enclosure 1. The second flexible sealing strip 15 connecting the side panels 10 to the frameless glass door 2 reduces heat loss and energy consumption.

[0079] The refrigerated compartment 6 has inclined frame columns 61 on both sides. Multiple shelves 16 are mounted on the frame columns 61, each shelf having a support arm 161 connected to one of the two frame columns 61, and a crossbeam 162 mounted on the support arm 161. Glass shelves are installed on the shelves 16 to support goods. The support arms 161 are inclined upwards, which not only supports goods but also allows the inclined shelves 16 to align with the buyer's line of sight. The inclined frame columns 61, combined with the shelves 16, create a more layered look for the goods displayed in the refrigerated compartment. Both the first installation area 7 and the second installation area 8 are equipped with condensing devices 17. Return air vents 18, connected to the condensing devices 17, are located at the top and bottom of the inner side of the refrigerated compartment 6. The return air vents 18 maintain the temperature inside the compartment and also function as an air curtain cabinet. Combined with the closed frameless glass door 2, this reduces heat loss from the refrigerated compartment 6 and lowers energy consumption.

[0080] A light box 5 is installed on the upper side of the cabinet 1, and a light box light is installed inside the light box 5. An inner ceiling light is installed inside the cabinet 1, and shelf lights are installed on the shelf rack 16. The light box light, inner ceiling light, and shelf lights can be turned on according to the application requirements of the scenario.

[0081] The frameless glass door 2 rotates along the door hinge assembly 211. The second connecting part 2142 is connected to the door hinge connector 20 and rotates with the frameless glass door 2, driving the first connecting part 2141 to rotate. When the frameless glass door 2 opens to a certain angle, the limiting assembly 214 will restrict the frameless glass door 2 from moving further. After releasing the hand, the frameless glass door 2 will automatically stop at a certain angle of movement. The hollow door hinge assembly 211 allows the door heating wire 4 to run from the center of the door hinge assembly 211. The door heating wire 4 heats the door hinge assembly 211 to remove the frameless glass. The fog on door 2 effectively prevents the door heating wire 4 from being exposed. When a frameless glass door 2 with a transparent frame is used, it will not affect the appearance. By providing an elastic reset part 212 and a fixing part 213 on the outside of the door hinge assembly 211, the elastic reset part 212 is used to make the door hinge connector 20 spring back to its original position. Since the door hinge connector 20 is connected to the frameless glass door 2, when the frameless glass door 2 rotates, the door hinge assembly 211 drives the elastic reset part 212 to generate torque. When the frameless glass door 2 is closed with a little force, the elastic reset part 212 resets and springs back.

[0082] The above examples are merely illustrative of the technical content of the present invention to facilitate easier understanding by the reader, but do not imply that the implementation of the present invention is limited to these examples. Any technical extensions or re-creations made based on the present invention are protected by the present invention. The scope of protection of the present invention is defined by the claims.
