Description

Technical Field

[0001] The utility model relates to the technical field of storage devices, in particular to a temperature insulation board and a dual-temperature air curtain cabinet. Background Art

[0002] In supermarkets, shopping malls, restaurants and other places, items such as fresh food or drinks are usually displayed or exhibited through air curtain cabinets.

[0003] A dual-temperature air curtain cabinet is provided in the related art, including a storage cavity, a cold air duct and a hot air duct arranged in sequence along the front-to-back direction. The storage cavity is divided into a cold zone and a hot zone arranged along the vertical direction. An insulation board is provided between the cold air duct and the hot air duct. The insulation board is provided with an opening, and the opening is used to allow the hot air in the hot air duct to pass through the cold air duct and then blow into the hot zone. The insulation board adopts a foaming process. During foaming, if a blocking piece is added to the opening, the foaming material will be blocked by the blocking piece when flowing to the blocking piece, and a cavity is likely to appear; if a blocking piece is not added, after the foaming is completed, the opening will be filled with the foaming material, and it is necessary to cut off the excess foaming material to form an opening, which increases the process and is not easy to operate. Therefore, the manufacturability of the insulation board is poor. Utility Model Content

The cabinet body 10 is provided with an article storage area 101, a cold air duct 104 and a hot air duct 107.

It can be understood that the cold air in the cold air duct 104 can be blown into the cold area 103. With this arrangement, cold air can be blown into the cold area 103 and hot air can be blown into the hot area 102, so that the cold area 103 maintains a lower temperature and the hot area 102 maintains a higher temperature, so that the cold area 103 and the hot area 102 meet the storage requirements of various articles at different temperatures.

The hot air duct 107, the ventilation hole 21 and the second air duct 106 are connected in sequence. The valve 30 is located between the first air duct 105 and the second air duct 106. The valve 30 is used to control the connection or disconnection of the first air duct 105 and the second air duct 106. Specifically, when the valve 30 is opened, the first air duct 105 and the second air duct 106 are connected, and the dual-temperature air curtain cabinet is in full-cold mode, and the cold air duct 104 blows cold air to the entire item storage area 101; when the valve 30 is closed, the first air duct 105 and the second air duct 106 are disconnected, and the dual-temperature air curtain cabinet is in dual-temperature mode, and the hot air duct 107 blows hot air into the second air duct 106 through the ventilation holes 21 on the insulation board 20, and the second air duct 106 blows hot air to the hot zone 102, and the first air duct 105 blows cold air to the cold zone 103.

The valve 30 is a partition, and the partition is slidably connected to the partition assembly 40. The partition can be extended or retracted relative to the partition assembly 40. When the partition is extended, the partition extends into the cold air duct 104 and divides the cold air duct 104 into a first air duct 105 and a second air duct 106 that are not connected to each other. When the partition is retracted, the first air duct 105 and the second air duct 106 are connected, and the partition is located below or inside the partition assembly 40.

[0054] As an alternative solution, the cabinet 10 also includes an intermediate channel (not shown in the drawings), which is arranged in the cold air duct 104, one end of the intermediate channel is connected to the ventilation holes 21 on the insulation board 20, and the other end of the intermediate channel is connected to the hot zone 102, and the hot air in the hot air duct 107 can be blown into the hot zone 102 through the ventilation holes 21 of the insulation board 20 and the intermediate channel.

[0055] Optionally, please continue to refer to Figure 2 The dual-temperature air curtain cabinet also includes a refrigeration mechanism 50 arranged in the cabinet body 10, and the refrigeration mechanism 50 includes a compressor 501, an evaporator 502, an expansion valve 503 and a condenser 504 that constitute a circulation loop, and an evaporator fan 505 and a condenser fan 506 are also provided in the cabinet body 10. The evaporator fan 505 is used to blow the cold energy emitted by the evaporator 502 to the first air duct 105 of the cold air duct 104, and the condenser fan 506 is used to blow the heat emitted by the condenser 504 to the hot air duct 107.

[0056] Optionally, the dual-temperature air curtain cabinet further includes a heater 60 disposed in the hot air duct 107 , and the heater 60 is used to further heat the air in the hot air duct 107 to ensure that the temperature of the hot air output from the hot air duct 107 is stable.

[0057] Optionally, see Figures 3 to 5 and Figure 8The insulation board 20 includes a board body 1, a blocking member 2 and a diverter member 3, wherein the board body 1 includes a first plate 11 and a second plate 12 arranged relatively spaced apart along a first direction, the board body 1 also includes a foaming space 15 located between the first plate 11 and the second plate 12, an injection port 131 connected to the foaming space 15, and an opening 16 penetrating the first plate 11 and the second plate 12 at the same time; the blocking member 2 is embedded in the opening 16 and penetrates the first plate 11 and the second plate 12 at the same time, the ventilation hole 21 is arranged in the blocking member 2, and the ventilation hole 21 penetrates both ends of the blocking member 2 along the first direction; the diverter member 3 is located between the injection port 131 and the blocking member 2, the diverter member 3 is connected to the first plate 11, and the diverter member 3 is spaced apart from the second plate 12, and the diverter member 3 is used to guide the foaming material entering from the injection port 131 and flowing to the blocking member 2 to flow to the side of the blocking member 2. The thermal insulation board 20 provided in the present embodiment is provided with a sealing member 2 for forming a ventilation hole 21 at the opening 16, and a diverter member 3 is arranged between the sealing member 2 and the injection port 131 to guide the foaming material to flow to the side of the sealing member 2 to prevent the sealing member 2 from blocking the flow of the foaming material; at the same time, part of the foaming material can flow into the space between the sealing member 2 and the diverter member 3 from the gap between the diverter member 3 and the second plate 12, which can ensure that the foaming material is evenly distributed in the entire foaming space 15 and avoid the problem of cavity. Therefore, the thermal insulation board 20 has better manufacturability.

[0058] Optionally, see Figure 4 In this embodiment, along the second direction (such as Figure 1 and Figure 4 The injection port 131 is opposite to the diverter 3, and the diverter 3 is opposite to the blocking member 2. The length of the blocking member 2 is along the third direction (as shown by the arrow cd). Figure 1 and Figure 4The diverter member 3 comprises a first diverter plate 31 and a second diverter plate 32, and the first end of the first diverter plate 31 and the first end of the second diverter plate 32 are connected at an angle, the second end of the first diverter plate 31 and the second end of the second diverter plate 32 extend to both ends of the length direction of the blocking member 2 respectively, and the first direction, the second direction and the third direction are arranged at an angle to each other. With such arrangement, the foaming material injected from the injection port 131 partially flows toward the diverter 3 under the action of pressure, and when the foaming material contacts the first diverter plate 31 and the second diverter plate 32, it can be divided into three parts by the diverter 3: the first part flows along the first diverter plate 31 and flows toward one side of the blocking member 2, and diffuses to the side of the blocking member 2 away from the injection port 131 after crossing the blocking member 2; the second part flows along the second diverter plate 32 and flows to the other side of the blocking member 2, and diffuses to the side of the blocking member 2 away from the injection port 131 after crossing the blocking member 2, and merges with the foaming material of the first part to jointly fill the space on the side of the blocking member 2 away from the injection port 131; the third part passes through the gap between the first diverter plate 31, the second diverter plate 32 and the second plate 12 to fill the area between the diverter 3 and the blocking member 2, so that the insulation board 20 provided in this embodiment is more uniform when foaming. Preferably, the first direction, the second direction and the third direction are perpendicular to each other. Further preferably, the center point of the injection port 131, the connection point between the first diverter plate 31 and the second diverter plate 32, and the length center point of the plugging member 2 are aligned along the second direction. In this way, the injection port 131 and the diverter plate 3 are directly opposite to each other along the second direction, so that when the foaming material enters the foaming space 15 from the injection port 131, it can be aligned with the intersection of the first end of the first diverter plate 31 and the first end of the second diverter plate 32, which is conducive to the foaming material flowing evenly to the two sides of the plugging member 2 through the diverter plate 3, further ensuring uniform foaming.

[0059] Optionally, the projections of the first and second diverter plates 31 and 32 along the second direction can cover the blocking member 2 in the third direction. This arrangement ensures that the foaming material will not contact the blocking member 2 when flowing along the first and second diverter plates 31 and 32, and moves more smoothly.

[0060] Optionally, see Figure 4 and Figure 5 The insulation board 20 further includes at least one support member 4, which is connected between the first board 11 and the second board 12 to support the first board 11 and the second board 12 to ensure the spacing therebetween. Preferably, the length of the blocking member 2 extends along the third direction, and along the third direction, the length of the support member 4 is much smaller than the length of the blocking member 2, so the support member 4 has little effect on the flow of the foaming material in the foaming space 15.

[0061] Optionally, see Figure 6 , Figure 8 and Fig. 9 , the flow divider 3 also includes a first connecting plate 33 and a second connecting plate 34, both of which are fixedly connected to the first plate 11. The first connecting plate 33 is connected to the first flow divider 31 at an angle, and the end of the first flow divider 31 away from the first connecting plate 33 is spaced from the second plate 12; the second connecting plate 34 is connected to the second flow divider 32 at an angle, and the end of the second flow divider 32 away from the second connecting plate 34 is spaced from the second plate 12. In this way, the flow divider 3 is connected to the first plate 11 through the first connecting plate 33 and the second connecting plate 34, which can ensure the connection stability of the flow divider 3 and the first plate 11; in addition, the first connecting plate 33 and the first flow divider 31 connected at an angle, and the second connecting plate 34 and the second flow divider 32 connected at an angle can significantly enhance the structural strength of the flow divider 3 itself, thereby ensuring that the flow divider 3 can withstand the impact of the foaming material and remain stable during foaming. Among them, the first connecting plate 33 and the second connecting plate 34 can be connected to the first plate 11 by riveting, bolting or welding. Specifically, in this embodiment, the first connecting plate 33 and the second connecting plate 34 are both provided with fixing holes 36, and the screws pass through the fixing holes 36 and are threadedly connected to the first plate 11. Preferably, the first connecting plate 33 is vertically connected to the first diverter plate 31, and the second connecting plate 34 is vertically connected to the second diverter plate 32.

[0062] As an alternative, see Figure 5 , the diverter 3 includes an arc-shaped plate 35, and the two ends of the arc-shaped plate 35 extend to the two ends of the length direction of the blocking member 2 respectively. With such a configuration, the foaming material injected by the injection port 131 partially flows to the diverter 3 under the action of pressure, and this part of the foaming material contacts the arc surface of the arc-shaped plate 35, and flows to the two sides of the blocking member 2 along the arc surface respectively. The contact resistance between the foaming material and the arc surface is small, which can significantly improve the diversion effect. Preferably, the center point of the injection port 131, the highest point of the arc-shaped plate 35 and the length center point of the blocking member 2 are aligned along the second direction. With such a configuration, the foaming material is first aligned with the highest point of the arc-shaped plate 35, which is conducive to the foaming material flowing evenly to the two sides of the blocking member 2 through the diverter 3.

[0063] As an alternative solution, the flow divider 3 includes a flow divider plate (not shown in the drawings) and a connecting plate (not shown in the drawings) connected to the flow divider plate at an angle, the flow divider plate is used to guide the foaming material entering from the injection port 131 and flowing toward the plugging member 2 to flow to the side of the plugging member 2, and the end of the flow divider plate away from the connecting plate is spaced apart from the second plate 12, and the connecting plate is connected to the first plate 11 in an adjustable position along the second direction, and the second direction is set at an angle to the first direction. Such a configuration makes it easy to adjust the relative position between the flow divider plate and the plugging member 2, thereby adjusting the foaming effect. Specifically, in this embodiment, the connecting plate is provided with a long hole extending along the second direction, and is fixedly connected to the first plate 11 by a fastener passing through the long hole. When the fastener is in a loose state, the diverter 3 can be moved along the length direction of the long hole, thereby adjusting the relative position between the diverter 3 and the blocking member 2. When the diverter 3 is in a position where the foaming material can fill the space between the diverter 3 and the blocking member 2 while also filling other foaming spaces 15, it can ensure that the foaming is more uniform; when the fastener is in a fastened state, the relative position of the diverter 3 and the first plate 11 can be locked, thereby locking the relative position between the diverter 3 and the blocking member 2.

[0064] Optionally, the diverter 3 is plugged into the first plate 11, and the diverter 3 can move relative to the first plate 11 along the first direction to adjust the gap between the diverter 3 and the second plate 12. In this way, the gap between the diverter 3 and the second plate 12 can be adjusted, and when the diverter 3 is located in a position that allows the foaming material to fill the space between the diverter 3 and the blocking member 2 while also filling other foaming spaces 15, it can ensure more uniform foaming.

[0065] Optionally, see Figure 4 , Figure 5 , Figure 7 and Figure 8 The board body 1 further includes a third board 13, which is arranged perpendicular to the first board 11, and a material injection port 131 is arranged on the third board 13, and along the first direction, the material injection port 131 is located between the first board 11 and the second board 12. In this way, the foaming material entering from the material injection port 131 flows directly along the first board 11 and the second board 12, which is more conducive to reducing the flow resistance of the foaming material, so that the foaming is more uniform. Preferably, the third board 13 is connected between the first board 11 and the second board 12, and further preferably, the first board 11 and the second board 12 are both rectangular, and the third board 13 is connected between one of the four sides of the first board 11 and the second board 12, and the board body 1 further includes a fourth board 14, a fifth board 17, and a sixth board 18, and the fourth board 14, the fifth board 17, and the sixth board 18 are respectively connected between the other three sides of the four sides of the first board 11 and the second board 12, so that the board body 1 is a rectangular plate structure as a whole.

[0066] Optionally, see Figure 8 and Fig. 9 The insulation board 20 further includes an elastic sheet 5, the first end of which is connected to the inner wall of the third plate 13, and the second end of which always has a tendency to approach the third plate 13 so that the elastic sheet 5 covers the injection port 131.
