Description

Technical Field

[0001] This utility model belongs to the technical field of refrigeration and freezing equipment, and particularly relates to a sealing structure for the front and rear sliding doors of a horizontal freezer and a horizontal freezer including the same. Background Technology

[0002] Horizontal freezers typically use sliding doors, which commonly include left-right sliding doors and front-back sliding doors. Compared to left-right sliding doors, front-back sliding doors can meet the needs of multiple people simultaneously taking goods from different sections, and have a wider range of applications.

[0003] To facilitate the sliding of the door, a track is typically installed on the frame of a horizontal freezer, with rollers on the side of the door. The rollers roll along the track to allow for easy sliding. However, the rollers create gaps between the door and the frame, affecting the door's seal and causing cold air to escape. Patent CN219982562U discloses a horizontal display cabinet with two positioning grooves on the track of the frame. When the front door is closed, two guide wheels at the front and rear of the front door fall into these grooves, eliminating gaps between the door and the track and improving the seal. However, the positioning grooves are through grooves, allowing cold air to escape through the gap between the guide wheels and the grooves, still failing to achieve a complete seal between the left and right sides of the front door and the frame.

[0004] Therefore, improving the sealing between the front and rear sliding doors of a horizontal freezer and the cabinet frame is a technical problem that urgently needs to be solved. Utility Model Content

[0005] To address the problem of insufficient sealing between the left and right sides of the existing front and rear sliding doors and the cabinet frame, this utility model provides a sealing structure for the front and rear sliding doors of a horizontal freezer and a horizontal freezer including the same. This sealing structure can achieve a complete seal between the left and right sides of the front and rear sliding doors and the cabinet frame, significantly improving the sealing performance between the front and rear sliding doors and the cabinet frame.

[0006] This utility model provides a sealing structure for the front and rear sliding doors of a horizontal freezer, including: The cabinet frame has a cabinet opening, and the side frames of the cabinet frame near the cabinet opening on the left and right sides are respectively provided with track surfaces extending in the front and back directions. The sliding door moves relative to the cabinet frame in the front-back direction to close and open the cabinet opening. The left and right edges of the bottom of the sliding door are respectively provided with two rollers that roll in cooperation with two track surfaces located on the left and right sides of the cabinet opening. The rollers that roll in cooperation with each track surface include a first roller located near the front end of the sliding door and a second roller located near the rear end of the sliding door. A receiving groove for accommodating a roller is formed in the portion of the side frame that has a track surface. The receiving groove includes a first receiving groove disposed near the front end of the track surface and a second receiving groove disposed behind the first receiving groove. In this design, a distance is left between the receiving groove and the edge of the track surface away from the cabinet opening in the left and right directions, so as to form an edge sealing area that is continuously set from the front end to the rear end of the track surface between the edge of the track surface away from the cabinet opening and the receiving groove; when the sliding door moves to the front end of the cabinet opening and is in the closed state, the first roller is received in the first receiving groove, the second roller is received in the second receiving groove, and the left and right sides of the bottom of the sliding door contact the two track surfaces located on the left and right sides of the cabinet opening. The edge sealing area of ​​the track surface and the bottom side edge of the sliding door form a sealing surface that is continuously set from the front end to the rear end of the sliding door.

[0007] This technical solution creates a continuous edge sealing area between the side of the track surface away from the cabinet opening and the receiving groove for accommodating the rollers of the sliding door, extending from the front end to the rear end of the track surface. When the sliding door is closed, as the rollers of the sliding door fall into the receiving groove, a continuous seal is formed between the edge sealing area and the bottom edge of the sliding door, extending from the front end to the rear end of the sliding door, thus completely sealing the gaps between the left and right sides of the sliding door and the cabinet opening frame.

[0008] In some embodiments, the receiving groove further includes a third receiving groove located near the rear end of the track surface. When the sliding door moves to the rear end of the cabinet opening state, the first roller is received in the second receiving groove, and the second roller is received in the third receiving groove. This technical solution, through the cooperation of the third and second receiving grooves, can restrict the sliding door to the open cabinet opening state, making it convenient for users to take goods from the cabinet.

[0009] In some embodiments, the side of the receiving slot near the cabinet opening is connected to the cabinet opening. This technical solution facilitates the removal of foreign objects that fall into the receiving slot by connecting one side of the receiving slot to the cabinet opening.

[0010] In some embodiments, the width of the receiving groove is 2-5 mm wider than the width of the roller. This technical solution, by making the width of the receiving groove slightly wider than the width of the roller, ensures that the roller can still fall into the receiving groove when the sliding door body shifts left or right, thus ensuring the normal closing of the sliding door body.

[0011] In some embodiments, the distance between the receiving groove and the edge of the track surface away from the cabinet opening in the left-right direction is at least 2 mm to ensure that the formed edge sealing area has sufficient width, thereby ensuring the sealing performance of the formed sealing surface.

[0012] In some embodiments, a front sealing strip is installed at the front end of the sliding door. When the sliding door moves to the front of the cabinet opening and is in a closed state, the front sealing strip abuts against the front frame of the cabinet opening to seal the gap between the front end of the sliding door and the front frame. This technical solution improves the sealing performance between the front end of the sliding door and the cabinet opening frame by installing a front sealing strip at the front end of the sliding door.

[0013] In some embodiments, the front sealing strip is an airbag sealing strip. This technical solution uses an airbag sealing strip as the front sealing strip, which, while achieving a seal, can also buffer the impact force on the front frame when the sliding door is closed.

[0014] In some embodiments, a shielding element is provided on the side of the front frame facing the cabinet opening. When the front sealing strip abuts against the front frame, the shielding element is positioned above the front sealing strip to block it. This technical solution, by using a shielding element to block the front sealing strip, can prevent foreign objects from falling into the gap between the front sealing strip and the front frame, while also improving aesthetics.

[0015] In addition, this utility model also provides a horizontal freezer, including a cabinet body, a cabinet opening frame at the top of the cabinet body, and a sliding door that moves relative to the cabinet opening frame in a front-to-back direction. The sliding door and the cabinet opening frame are sealed using the sealing structure of the front and rear sliding doors of the horizontal freezer described in any of the above-mentioned technical solutions. This horizontal freezer, using the sealing structure of the front and rear sliding doors of the horizontal freezer described in any of the above-mentioned technical solutions, improves the freezer's heat preservation performance, reduces cold air loss, and lowers energy consumption.

[0016] In some embodiments, a fixed door is also installed on the cabinet frame, which is fixedly installed at the rear of the cabinet frame. A sliding door is located below the fixed door. A first sealing strip is provided on the top surface of the rear end of the sliding door, and a second sealing strip is provided on the bottom surface of the front end of the fixed door. When the sliding door moves to the front end of the cabinet opening, the fixed door and the sliding door together close the cabinet opening, and the first and second sealing strips abut against each other to seal the gap between the sliding door and the fixed door. This technical solution closes the cabinet opening through the cooperation of the fixed door and the sliding door, requiring only one sliding door. Simultaneously, the cooperation of the first and second sealing strips achieves a seal between the sliding door and the fixed door, improving the refrigerator's insulation performance, reducing cold air loss, and lowering energy consumption.

[0017] Based on the above technical solution, the sealing structure of the front and rear sliding doors of the horizontal refrigerator provided in this utility model embodiment forms an edge sealing area that is continuously set from the front end to the rear end of the track surface on the side away from the cabinet opening and the receiving groove for accommodating the rollers of the sliding door when the sliding door is closed. This allows the edge sealing area to form a continuous seal from the front end to the rear end of the sliding door when the rollers of the sliding door fall into the receiving groove, thereby completely sealing the gaps between the left and right sides of the sliding door and the cabinet opening frame.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] In existing horizontal freezers, although a receiving groove is set on the track of the cabinet opening frame so that when the sliding door is closed, the rollers of the sliding door fall into the receiving groove, thus eliminating gaps between the sliding door and the track and increasing the seal between the sliding door and the cabinet opening frame; however, the receiving groove is a through groove, which allows cold air inside the cabinet to escape outward from the gap between the rollers and the receiving groove.

[0025] To achieve a complete seal between the left and right sides of the sliding door and the cabinet frame, as shown in the attached document... Figures 1-10 As shown in the schematic embodiment of the sealing structure of the front and rear sliding doors of the horizontal refrigerator of this utility model, the sealing structure of the front and rear sliding doors of the horizontal refrigerator includes a cabinet frame 1, a sliding door 2, and a receiving groove b; the cabinet frame 1 forms a cabinet opening e, and the side frames 11 of the cabinet frame 1 near the cabinet opening e are respectively provided with track surfaces a extending in the front-rear direction; the sliding door 2 moves relative to the cabinet frame 1 in the front-rear direction to close and open the cabinet opening e, and the left and right edges of the bottom of the sliding door 2 are respectively provided with rollers 23 that roll in cooperation with the two track surfaces a located on the left and right sides of the cabinet opening e. The rollers 23 that roll in cooperation with each track surface a include a first roller 231 located near the front end of the sliding door 2 and a second roller 232 located near the rear end of the sliding door 2; the receiving groove b is used to receive the rollers 23, and it is opened on the side frame 11 where the track surfaces a are located. Part of the receiving groove b includes a first receiving groove b1 located near the front end of the track surface a and a second receiving groove b2 located behind the first receiving groove b1; wherein, in the left and right direction, there is a distance between the receiving groove b and the edge of the track surface a away from the cabinet opening e, so as to form an edge sealing area c continuously arranged from the front end to the rear end of the track surface a between the edge of the track surface a away from the cabinet opening e and the receiving groove b; when the sliding door body 2 moves to the front end of the cabinet opening e and the cabinet opening e is closed, the first roller 231 is received in the first receiving groove b1, the second roller 232 is received in the second receiving groove b2, and the left and right sides of the bottom of the sliding door body 2 contact the two track surfaces a located on the left and right sides of the cabinet opening e, and the edge sealing area c of the track surface a and the bottom side edge of the sliding door body 2 form a sealing surface d continuously arranged from the front end to the rear end of the sliding door body 2.

[0026] The working principle of the sealing structure of the front and rear sliding doors of the above-mentioned horizontal refrigerator is as follows: When the first roller 231 and the second roller 232 of the sliding door 2 roll along the two track surfaces a set on the left and right sides of the cabinet opening e, so as to drive the sliding door 2 to move from back to front to the position of closing the cabinet opening e, the first roller 231 falls into the first receiving groove b1 and the second roller 232 falls into the second receiving groove b2. At this time, the sliding door 2 will move downward, so that the bottom left and right edges of the sliding door 2 contact the two track surfaces a located on the left and right sides of the cabinet opening e. Because there is a distance between the receiving groove b and the edge of the track surface a away from the cabinet opening e in the left and right directions to form an edge sealing area c that is continuously set from the front end to the rear end of the track surface a, the receiving groove b does not penetrate the entire track surface a in the left and right directions. When the bottom side edge of the sliding door body 2 contacts the track surface a, the edge sealing area c of the track surface a and the bottom side edge of the sliding door body 2 form a sealing surface d that is continuously set from the front end to the rear end of the sliding door body 2, thereby completely sealing the gap between the left and right sides of the sliding door body 2 and the cabinet opening frame 1.

[0027] The sealing structure of the front and rear sliding doors of the above-mentioned horizontal refrigerator forms an edge sealing area c that is continuously set from the front end to the rear end of the track surface a on the side away from the cabinet opening e and the receiving groove b for accommodating the roller 23 of the sliding door 2 when the sliding door 2 is closed. This ensures that when the sliding door 2 is closed, as the roller 23 of the sliding door 2 falls into the receiving groove b, the edge sealing area c and the bottom side edge of the sliding door 2 form a continuous seal from the front end to the rear end of the sliding door 2, thereby completely sealing the gaps between the left and right sides of the sliding door 2 and the cabinet opening frame 1.

[0028] It should be noted that, as Figure 2 , Figure 4 and Figure 8 As shown, the sliding door 2 includes a door glass 21 and door connectors 22 installed on the left and right sides of the door glass 21. Rollers 23 are installed at the bottom of the door connectors 22. When the sliding door 2 moves to the closed position, the bottom surface of the door connectors 22 contacts the track surface a to form a sealing surface d. It should also be noted that the rollers 23 are preferably rubber-coated bearing rollers to reduce the noise when the rollers 23 roll along the track surface a, and at the same time make the rolling of the rollers 23 more flexible.

[0029] In some embodiments, such as Figure 6 and Figure 7 As shown, the receiving groove b is connected to the cabinet opening e on the side closest to the cabinet opening e. This arrangement of the receiving groove b facilitates the cleaning of foreign objects that fall into it, and also makes it easier to machine the receiving groove b on the side frame 11 of the cabinet opening frame 1.

[0030] In some embodiments, preferably, the width of the receiving groove b is 2-5 mm wider than the width of the roller 23. By making the width of the receiving groove b slightly wider than the width of the roller 23, the roller 23 can still fall into the receiving groove b when the sliding door 2 shifts left or right, ensuring the normal closing of the sliding door 2.

[0031] In some embodiments, preferably, the distance between the receiving groove b and the edge of the track surface a away from the cabinet opening e in the left-right direction is at least 2 mm, so as to ensure that the formed edge sealing area c has sufficient width, thereby ensuring the sealing performance of the formed sealing surface d.

[0032] In some embodiments, such as Figure 6 , Figures 11-13 As shown, the receiving groove b also includes a third receiving groove b3 located near the rear end of the track surface a. When the sliding door 2 moves to the rear end of the cabinet opening e and is in the open cabinet opening e state, the first roller 231 is received in the second receiving groove b2, and the second roller 232 is received in the third receiving groove b3. Through the cooperation of the third receiving groove b3 and the second receiving groove b2, the sliding door 2 can be restricted to the open cabinet opening e state, making it convenient for users to take goods from the cabinet 4.

[0033] In existing horizontal freezers, a sealing strip is typically installed on the front edge of the cabinet frame to seal the gap between the front end of the sliding door and the cabinet frame. However, this method suffers from incomplete sealing due to misalignment between the sliding door and the sealing strip. To improve the sealing performance between the front end of the sliding door 2 and the cabinet frame 1, in some embodiments, such as... Figure 4 , Figure 8 and Figure 9 As shown, a front sealing strip 24 is installed at the front end of the sliding door 2. When the sliding door 2 moves to the front end of the cabinet opening e and is in the closed state, the front sealing strip 24 abuts against the front frame 12 of the cabinet opening frame 1 located in front of the cabinet opening e to seal the gap between the front end of the sliding door 2 and the front frame 12. In this embodiment, by installing a front sealing strip 24 at the front end of the sliding door 2, misalignment between the sliding door 2 and the front sealing strip 24 can be avoided, ensuring the sealing between the front end of the sliding door 2 and the cabinet opening frame 1. Preferably, the front sealing strip 24 is an airbag sealing strip. Using an airbag sealing strip as the front sealing strip 24 can achieve sealing while buffering the impact force on the front frame 12 when the sliding door 2 is closed.

[0034] In some embodiments, such as Figure 4 and Figure 7As shown, a shielding member 121 is provided on the side of the front frame 12 facing the cabinet opening e. When the front sealing strip 24 abuts against the front frame 12, the shielding member 121 is positioned above the front sealing strip 24 to block it. By shielding the front sealing strip 24 with the shielding member 121, foreign objects can be prevented from falling into the gap between the front sealing strip 24 and the front frame 12, while also improving the aesthetics.

[0035] Based on the aforementioned sealing structure of the front and rear sliding doors of the horizontal freezer, such as Figure 14 and Figure 15 As shown, this utility model also provides a horizontal freezer, including a cabinet body 4. A cabinet frame 1 is provided at the top of the cabinet body 4. A sliding door 2, which moves relative to the cabinet frame 1 in a front-to-back direction, is installed on the cabinet frame 1. The sliding door 2 and the cabinet frame 1 are sealed using the aforementioned sealing structure of the front and rear sliding doors of the horizontal freezer. This horizontal freezer, by employing the aforementioned sealing structure of the front and rear sliding doors, improves the freezer's heat preservation performance, reduces cold air loss, and lowers energy consumption.

[0036] In some embodiments, such as Figures 14-16 As shown, the cabinet frame 1 is also equipped with a fixed door 3, which is fixedly installed at the rear of the cabinet frame 1. A sliding door 2 is located below the fixed door 3. The top surface of the rear end of the sliding door 2 is provided with a first sealing strip 25, and the bottom surface of the front end of the fixed door 3 is provided with a second sealing strip 31. When the sliding door 2 moves to the front end of the cabinet opening e, the fixed door 3 and the sliding door 2 together close the cabinet opening e, and the first sealing strip 25 and the second sealing strip 31 abut against each other to seal the gap between the sliding door 2 and the fixed door 3. By cooperating to close the cabinet opening e, only one sliding door 2 is needed, reducing the loss of cold air. Simultaneously, the first sealing strip 25 on the sliding door 2 and the second sealing strip 31 on the fixed door 3 achieve a seal between the sliding door 2 and the fixed door 3, improving the refrigerator's insulation performance, reducing cold air loss, and lowering energy consumption. It should be noted that, as Figure 16 As shown, when the first sealing strip 25 and the second sealing strip 31 abut against each other, the first sealing strip 25 is located behind the second sealing strip 31.

[0037] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0038] The above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
