Description

Technical Field

[0001] This invention relates to the field of food storage cabinet technology, and more particularly to an open-style pastry cabinet. Background Technology

[0002] With societal development, supermarkets and small shops are increasingly using pastry display cases. These cases need to be kept within a certain low-temperature range to ensure the freshness of the pastries displayed inside.

[0003] In existing pastry display cases, the case is typically rectangular with two longer, opposite sides: one for serving and the other for displaying cakes. To ensure high cooling efficiency, large internal airflow, and fast circulation, a long, narrow air outlet is usually located on the bottom of the display chamber near the edge of the door, while a long, narrow air inlet is located on the opposite side near the serving area. However, since pastries are generally placed on shelves inside the display case, this bottom-mounted airflow cooling method results in good cooling at the bottom, while the top remains poorly cooled due to limited airflow. Consequently, the pastries on the shelves do not receive even and complete contact with the cold air, leading to poor preservation. Summary of the Invention

[0024] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0025] Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first," "second," and "third" may explicitly or implicitly include one or more of that feature.

[0026] A preferred embodiment of this application, such as Figures 1 to 7As shown, an open-style pastry display case 1 includes a base 3, a pastry cabinet 1, and a pastry rack 2. The base 3 has a refrigeration unit inside. The pastry cabinet 1 is located on top of the base 3 and has an installation cavity 11 inside. The front side of the installation cavity 11 has a serving window 12, and the rear side has an openable cabinet door 13. The installation cavity 11 has a connection port 15 near the bottom edge of the cabinet door 13, which communicates with the air outlet 32 ​​of the refrigeration unit. The installation cavity 11 also has an air inlet 14 near the bottom edge of the serving window 12, which communicates with the air return vent 31 of the refrigeration unit. The cabinet door 13 has a vertical ventilation groove 131 inside. When the cabinet door 13 is closed, the bottom of the ventilation groove 131 is connected to the connection port 15. When the cabinet door 13 is open, the bottom of the ventilation groove 131 is separated from the connection port 15. The pastry rack 2 is installed inside the installation cavity 11.

[0027] In this embodiment, the pastry rack 2 is used to hold pastries; customers can take pastries from the pastry rack 2 through the serving window 12. Furthermore, the pastry cabinet 1 of this application can be placed directly in a certain location in the pastry shop. When there are few pastries left on the pastry rack 2, they can be replenished from the serving window 12. The pastry cabinet 1 of this application can also be applied to the serving outlet of the pastry kitchen, with the rear side of the pastry cabinet 1 fitting against the serving outlet of the pastry kitchen. When the pastries on the pastry rack 2 need to be replenished, the cabinet door 13 can be opened to directly replenish pastries from the serving outlet of the pastry kitchen, thereby facilitating the replenishment of pastries, reducing the time spent transferring pastries, and improving work efficiency. Furthermore, the cabinet door 13 has a vertical ventilation slot 131 inside. When the cabinet door 13 is closed, the bottom of the ventilation slot 131 is connected to the connection port 15, so that the cold air from the refrigeration device is discharged from the air outlet 32, then enters the ventilation slot 131 through the connection port 15, and then is discharged from the top of the ventilation slot 131. In this embodiment, the top of the ventilation slot 131 is connected to the top of the mounting cavity 11, so that the cold air flows from the ventilation slot 131 to the top of the mounting cavity 11, and then flows to the bottom of the mounting cavity 11 under gravity, and finally flows back to the refrigeration device from the air inlet 14, completing the air circulation. Compared with the prior art, this setting prevents the top of the mounting cavity 11 from being unable to exhaust cold air, thus avoiding poor cooling effect and poor preservation of pastries. Moreover, the cold air will flow back to the bottom due to gravity, ensuring that there is cold air circulation in the mounting cavity 11, thereby ensuring that the cold air can evenly contact the pastries on the pastry rack 2. When the cabinet door 13 is open, the ventilation slot 131 will also rotate with the cabinet door 13. The ventilation slot 131 is not located in the mounting cavity 11 and is separated from the connection port 15. Then, the cold air is directly discharged from the connection port 15 into the mounting cavity 11 and will not enter the ventilation slot 131.

[0028] The cabinet door 13 includes a hinge structure 136; the hinge structure 136 includes a hinge base 1361 and a rotating shaft 1362; the hinge base 1361 is fixedly installed on the top surface of the base 3; one end of the rotating shaft 1362 is fixedly installed on the hinge base 1361, and the other end of the rotating shaft 1362 is rotatably connected to the cabinet door 13, so that the cabinet door 13 can rotate around the rotating shaft 1362. The cabinet door 13 opens or closes by rotating around the rotating shaft 1362, thereby facilitating the replenishment of pastries to the pastry cabinet 1, reducing transfer time, and improving work efficiency; and the hinge structure 136 is simple and compact, allowing the cabinet door 13 to rotate smoothly, reducing the assembly time of the cabinet door 13.

[0029] The cabinet door 13 includes a first door panel 133, a heat insulation plate 135, and a second door panel 134; the first door panel 133 is located on the side closer to the mounting cavity 11, the second door panel 134 is located on the side away from the mounting cavity 11, and the heat insulation plate 135 is located between the second door panel 134 and the first door panel 133; the first door panel 133, the heat insulation plate 135, and the second door panel 134 are spaced apart; the gap between the heat insulation plate 135 and the first door panel 133 is the ventilation groove 131.

[0030] The first door panel 133 and the second door panel 134 are both made of glass; the heat insulation panel 135 is made of a heat-insulating and transparent material.

[0031] In this embodiment, the heat insulation panel 135 is made of polymethyl methacrylate (PMMA); PMMA, also known as acrylic or plexiglass, has high transparency, is easy to machine, and is a commonly used glass alternative. In other embodiments, the heat insulation panel 135 can be made of other transparent materials with heat insulation properties. Specifically, the first door panel 133 is installed on the side close to the mounting cavity 11 and in contact with the mounting cavity 11; the second door panel 134 is installed on the side away from the mounting cavity 11 and in contact with the pastry kitchen. The mounting cavity 11 generally contains cold air and has a low temperature; the pastry kitchen has a higher temperature due to the making of pastries. Therefore, there is a temperature difference between the first door panel 133 and the second door panel 134. Since both the first door panel 133 and the second door panel 134 are made of glass, water vapor will form between the first door panel 133 and the second door panel 134, making it impossible to directly observe the situation inside the pastry cabinet 1 from inside the pastry kitchen. Therefore, a heat-insulating and transparent heat-insulating plate 135 is installed between the first door panel 133 and the second door panel 134 to avoid and reduce temperature differences, thereby preventing water vapor from forming on the cabinet door 13. The quantity of pastries inside the pastry rack 2 can be directly observed from the rear side of the pastry cabinet 1. More preferably, the heat-insulating plate 135 prevents heat exchange between the cold air and the outside environment, thus reducing the consumption of cooling energy.

[0032] The first door panel 133 is provided with multiple ventilation holes 132. Specifically, the purpose of this arrangement is to allow cold air to enter the mounting cavity 11 evenly, ensuring uniform cooling within the mounting cavity 11, thereby ensuring the preservation effect.

[0033] A baffle plate 121 is provided at the top of the serving window 12. Cold air discharged from the refrigeration unit enters the ventilation duct 131 and flows directly from the top of the ventilation duct 131 to the top of the mounting cavity 11. The purpose of providing the baffle plate 121 in the serving window 12 is to prevent the cold air flowing from the ventilation duct 131 to the top of the mounting cavity 11 from flowing directly out of the pastry display case. Instead, the cold air flows downwards and then back into the refrigeration unit through the air inlet 14, completing air circulation and reducing energy waste.

[0034] The pastry rack 2 includes multiple support rods 21 and multiple placement horizontal plates 22; the bottoms of the multiple support rods 21 are fixedly installed at the bottom of the mounting cavity 11, and the multiple support rods 21 form a square; the interior of each support rod 21 is provided with a first wire groove 211; the multiple placement horizontal plates 22 are evenly spaced in the vertical direction, and the four top corners of each placement horizontal plate 22 are fixedly connected to the support rods 21; the gap between two adjacent placement horizontal plates 22 is a pastry placement layer 200; the ventilation hole structure 132 is positioned opposite to the pastry placement layer 200; the left and right sides of each placement horizontal plate 22 are provided with a second wire groove and a wire outlet hole 221; the bottom of each placement horizontal plate 22 is also provided with a light groove 222; the light groove 222 communicates with the wire outlet hole 221; the wire outlet hole 221 communicates with the second wire groove; the second wire groove communicates with the first wire groove 211. The pastry placement layer 200 is directly opposite the ventilation hole structure 132. This arrangement ensures that the cold air blowing out of the ventilation hole structure 132 can directly reach the pastries on the pastry placement layer 200, maximizing cooling efficiency. Furthermore, the first and second wire channels are used for pre-installing electrical wires, while the light trough 222 is used to install decorative lights. The decorative lights are connected to the electrical wires through the wire outlet 221, thereby decorating and illuminating the pastry display cabinet, making it aesthetically pleasing.

[0035] The pastry rack 2 and the pastry display case 1 are integrally formed. This design allows for easy installation of wires in the first and second wire channels 211, and the wires do not protrude beyond the first and second wire channels, thus maintaining the aesthetic appearance of the pastry display case 1.

[0036] The refrigeration device also includes an outer cover 30 and an air guide plate 33; the return air inlet 31 of the refrigeration device is located on the front side of the outer cover 30; the air outlet 32 ​​of the refrigeration device is located on the rear side of the outer cover 30; one end of the air guide plate 33 is connected to the rear side of the outer cover 30; the other end of the air guide plate 33 is inclined upward and connected to the base 3. The purpose of setting the air guide plate 33 is to ensure that after the cold air is discharged from the refrigeration device, it flows smoothly upward into the ventilation slot 131 under the guidance of the air guide plate 33, thereby reducing the loss of cold air.

[0037] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of the invention and should not be construed as limiting the scope of protection of the invention in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of the invention without inventive effort, and these embodiments will all fall within the scope of protection of the present invention.
