Description

Technical Field

[0001] This application relates to the field of ice-making equipment, and more particularly to a hovering door structure for an ice maker. Background Technology

[0002] In the daily operation of a beverage shop, the ice maker is one of the core pieces of equipment, and it is used very frequently. Taking a typical beverage shop with an average daily customer flow of 200 people as an example, the ice maker needs to be turned on and off to dispense and replenish ice about 8-10 times per hour, and during peak hours it can even reach more than 15 times per hour.

[0003] For such high-frequency usage scenarios, most ice makers on the market use sliding doors, hinged doors, or pull-open doors. However, these door opening mechanisms either allow the door to open completely or close completely, and there is a possibility that the door may not close properly or pose a risk of injury from falling objects. Therefore, it is essential to develop a safe and reliable door opening mechanism. Utility Model Content

[0004] In order to improve the existing problems of ice makers where the door cannot be suspended when opened, and the risk of injury from falling objects when automatically closing, this application provides a suspended door opening structure for an ice maker.

[0005] The suspended door opening structure of an ice maker provided in this application adopts the following technical solution: A hovering door structure for an ice maker includes a main housing with an ice-retrieving opening at the front end. An unfolding plate is located inside the main housing on one side of the ice-retrieving opening. One end of the unfolding plate is externally connected to a hovering door for opening and closing the ice-retrieving opening. A movable rod is inserted and limited inside the main housing at one end of the unfolding plate. The movable rod moves within the main housing and reciprocates with the top of the unfolding plate. The unfolding plate and the movable rod are inserted at different positions, causing the unfolding plate to be at different opening and closing angles. These different opening and closing angles cause the hovering door to hover.

[0006] By adopting the above technical solution, the hovering door drives the unfolding plate to unfold, thereby pressing against the moving rod and applying a pushing force. The moving rod moves under the pushing force to prevent interference when the hovering door is moving. At the same time, when the hovering door loses its power supply, the moving rod moves in the opposite direction to lock the unfolding plate, thereby keeping the hovering door in its current stopped position.

[0007] Preferably, the main housing has an internal cavity for installing power supply equipment, which is connected to the ice extraction port, and a storage liner is fixed to the top of the internal cavity.

[0008] By adopting the above technical solution, the bottom of the installation cavity provides space for the installation of the power supply, while the top of the installation cavity provides installation space for the storage liner.

[0009] Preferably, a fixing plate is fixedly provided on the outer surface of the storage liner near the unfolding plate, and a connecting groove is opened at the front end of the storage liner at the position of the fixing plate, and the unfolding plate is movably inserted into the connecting groove.

[0010] By adopting the above technical solution, the opening of the connecting groove provides space for the insertion of the unfolding plate, so that the unfolding plate is inserted into the fixed plate through the connecting groove to form a snap-fit ​​operation. At the same time, the fixed plate is located on one side of the outer surface of the storage liner to form a fixing effect, and the connection structure with the unfolding plate is separated from the outside of the storage liner.

[0011] Preferably, a transverse limiting plate is fixed to the side of the fixing plate facing the storage liner, and two longitudinal fixing members are fixed to the side of the transverse limiting plate facing the storage liner.

[0012] By adopting the above technical solution, the installation of the lateral limiting plate provides fixing screw mounting points for the two longitudinal fixing parts, and at the same time, the lateral limiting plate limits the two longitudinal fixing parts, thereby stably setting it in the middle of the lateral limiting plate and forming a detachable fixing state.

[0013] Preferably, a movable rod is movably provided between the two longitudinal fixing members, with the upper and lower ends of the movable rod passing through the two longitudinal fixing members respectively to form a movable insertion.

[0014] By adopting the above technical solution, the moving rod is movably interspersed within the two longitudinal fixing members, thereby abutting against the extension plate during the downward movement to form a fixing effect, thus keeping the hovering door in a hovering state.

[0015] Preferably, a limiting ring is provided on the surface of the movable rod between two longitudinal fixing members, and an extension spring is fixedly provided around the top of the limiting ring around the movable rod. The top of the extension spring is fixedly connected to one of the longitudinal fixing members located above.

[0016] By adopting the above technical solution, the opening of the limiting ring prevents the moving rod from being excessively moved out by the two longitudinal fixing parts, while providing a mounting fulcrum for the extension spring and the moving rod. The extension spring provides a rebound force to move the moving rod downward.

[0017] Preferably, the surface of the unfolding plate is provided with a snap-fit ​​toothed surface, and the unfolding plate is provided with a limit hook at the end of the snap-fit ​​toothed surface.

[0018] By adopting the above technical solution, the opening of the snap-fit ​​tooth surface and the limiting hook provides an abutment groove for the snap-fit ​​of the moving rod, thereby facilitating the receiving of the downward pressure of the moving rod to form the hovering effect of the hovering door.

[0019] Preferably, the bottom of the movable rod is provided with a bent surface for engaging with the engaging tooth surface and the limiting hook.

[0020] By adopting the above technical solution, the moving rod is pushed downward by the extension spring, thereby abutting against the groove of the locking tooth surface and the limiting hook, and thus fixing it as a whole with the unfolding plate, thereby forming a locking effect.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. By applying a pushing force to the hovering door, the force is transmitted from the unfolding plate to the bending surface, thereby generating an interaction force that causes the moving rod to move upward. The moving rod moves upward and is offset from the unfolding plate to avoid interfering with the unfolding plate's unfolding movement. When the hovering door loses its force, the upward pushing force on the moving rod is canceled, and the extension spring drives the moving rod to return to its original position, locking the bending surface and the locking tooth surface to fix it in place. This locks the current unfolding state of the unfolding plate and controls the hovering door to remain in a hovering state, avoiding the danger of collisions and injuries caused by the door not closing properly.

Detailed Implementation

[0024] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0025] This application discloses a hovering door opening structure for an ice maker.

[0026] Reference Figure 1 , Figure 2 , Figure 3A suspended door structure for an ice maker includes a main housing 1. An ice-receiving port 16 is provided at the front end of the main housing 1. The opening at the bottom of the ice-receiving port 16 is set as an inclined surface from bottom to top, and a groove is provided on the inclined surface. An installation cavity 5 extends from the ice-receiving port 16 into the interior of the main housing 1. The installation cavity 5 is rectangular in shape, and a power supply system and a cold circulation system are provided at the bottom of the installation cavity 5. At the same time, a ventilation slot is provided through the outer surface of the main housing 1 at the position where the power supply system and the cold circulation system are installed to provide auxiliary heat dissipation for the power supply system and the cold circulation system. The storage liner 2 is fixed to the top of the installation cavity 5 with screws, and a polyurethane foam layer is provided between the storage liner 2 and the inner wall of the main shell 1 to form a high-efficiency heat insulation layer to reduce the loss of cold energy. The evaporator of the cold circulation system is embedded in the inner surface of the storage liner 2 from bottom to top, so that the evaporator absorbs the heat of the water and freezes it. The connection between the evaporator and the storage liner 2 is filled with silver-based brazing filler metal, which is heated to the melting point of the brazing filler metal and then cooled and solidified to form a brazing seal to prevent refrigerant leakage. A fixing plate 6 is fixed to one side of the surface of the storage inner liner 2 with screws. The fixing plate 6 is in the shape of a U-shape, and the notch of the fixing plate 6 faces the side surface of the storage inner liner 2 to form a fixed connection. Thus, a rectangular space is formed by the notch of the fixing plate 6 and the outer surface of the storage inner liner 2. At the same time, a connecting groove 7 is opened through one side of the front end of the storage inner liner 2, and the connecting groove 7 is connected to the rectangular space of the fixing plate 6.

[0027] Reference Figure 3 , Figure 4 , Figure 5 A transverse limiting plate 8 is screwed onto one side of the rectangular space of the fixed plate 6. Both sides of the transverse limiting plate 8 have protruding plates. Two longitudinal fixing members 9 are fixed between the two protruding plates of the transverse limiting plate 8. The two longitudinal fixing members 9 and the two protruding plates of the transverse limiting plate 8 form a rectangular groove. A movable rod 10 is movably positioned between the two longitudinal fixing members 9. The upper and lower ends of the movable rod 10 respectively pass through the two longitudinal fixing members 9. The plate extending from the top of the transverse limiting plate 8 limits the top of the movable rod 10 (e.g., ...). Figure 5 As shown), this allows the movable rod 10 to move and intersect with the two longitudinal fixing members 9 while its top is limited by the transverse limiting plate 8 to prevent it from moving excessively upward. A limiting ring 11 is provided on the surface of the moving rod 10 between two longitudinal fixing members 9. The width of the limiting ring 11 is greater than the width of the through-hole between the moving rod 10 and the longitudinal fixing member 9. Under normal conditions, the limiting ring 11 fits against the upper end face of the lower longitudinal fixing member 9 to form a limit, thereby preventing the moving rod 10 from moving too far downward. An extension spring 12 is fixed around the moving rod 10 on the upper end face of the limiting ring 11. The top of the extension spring 12 is fixed to the bottom surface of the upper longitudinal fixing member 9. When the moving rod 10 moves upward, it compresses the extension spring 12. When the moving rod 10 stops moving, the extension spring 12 rebounds and drives the moving rod 10 back to its original position. The bottom of the moving rod 10 extends from the longitudinal fixing member 9 located below and is provided with a bending surface 13. The bending surface 13 bends at 90° with the rod body of the moving rod 10. At the same time, a hovering door 3 is provided in the recess of the ice-retrieving port 16. Rotating rods are fixed on both sides of the hovering door 3, and both sides of the rotating rods are rotatably connected to the inner walls of the groove of the ice-retrieving port 16, so that the entire hovering door 3 is rotatably connected to the surface of the main housing 1. An unfolding plate 4 is fixed on one side of the surface of the hovering door 3 at the position of the connecting groove 7. The unfolding plate 4 is 90° arc-shaped, and the surface of the unfolding plate 4 is inserted into the rectangular space of the fixing plate 6 through the connecting groove 7. A snap-fit ​​toothed surface 15 is provided on the surface of the unfolding plate 4. The width of the snap-fit ​​toothed surface 15 is the same as the width of the bending surface 13. When the moving rod 10 is pressed down, it drives the bending surface 13 to be pressed into the snap-fit ​​toothed surface 15, thereby forming an overall snap-fit ​​state between the moving rod 10 and the unfolding plate 4, ensuring that the unfolding plate 4 can be in a fixed unfolded state when the hovering door 3 is opened.

[0028] It should be noted that the width of the snap-fit ​​toothed surface 15 is set to 10mm and the depth is set to 5mm. A limiting hook 14 is provided at the end of the unfolding plate 4 located at the snap-fit ​​toothed surface 15. The limiting hook 14 extends at a 90° angle at the end of the snap-fit ​​toothed surface 15, with a width of 10mm, and is in a hook state. This limits the bending surface 13, ensuring a firm snap-fit ​​with the bending surface 13, so that the unfolding plate 4 can be unfolded up to 90° from the ice-receiving opening 16, thus forming a limit.

[0029] In this device, the extension spring 12 is normally in an extended state, continuously providing a thrust to the moving rod 10. The extension spring 12 mainly uses torque to represent its elastic effect, and its calculation formula is usually based on the spring stiffness (elastic coefficient). In this device, the extension spring 12 adopts the calculation formula of Taikin Lee Huang single spring: F=kx, where F is the external force on the spring, k is the spring constant, and x is the deformation of the spring.

[0030] The implementation principle of the suspended door opening structure of an ice maker according to the present application embodiment is as follows: When using this device, the person pulls the suspended door 3. As the suspended door 3 moves the unfolding plate 4 outward, the locking tooth surface 15 applies a pushing force to the bending surface 13 through the tooth surface. When the protruding part of the locking tooth surface 15 contacts the bending surface 13, the bending surface 13 moves upward to the highest point, causing the moving rod 10 to move longitudinally within the two longitudinal fixing parts 9. At this time, the suspended door 3 unfolds outward normally, and the extension spring 12 is in a compressed state. As the person stops pulling the hovering door 3, the unfolding plate 4 is in a stationary state, the pushing force applied to the bending surface 13 is released, and the extension spring 12 rebounds downward, applying the rebound force to the limiting ring 11, thereby pushing the moving rod 10 back to its original position. During the process of the moving rod 10 returning to its original position, it pushes the bending surface 13 to re-engage with the recessed part of the locking tooth surface 15, thereby forming a locking and fixing of the unfolding plate 4, so that the hovering door 3 remains in its current unfolded state. At this time, personnel collect ice from the storage liner 2 through the exposed ice collection port 16. After collection, they push the unfolding plate 4 to allow the hovering door 3 to cover the ice collection port 16 again and return to its original position, effectively avoiding the problem of the door not closing properly or the potential danger of injury from opening the door.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
